Starting, Lighting, & Ignition (SLI) Batteries
Yes. Even if the automatic start-stop system has been switched off temporarily or permanently, a start-stop battery (EFB or AGM, matching the original OE specification) is still required. Here's why:
Never install a conventional starter battery in a vehicle that was originally fitted with an EFB or AGM battery, not even if the start-stop function is disabled. Modern vehicles place enormous cyclic demands on the battery through their additional electrical and electronic consumers alone. Without the alternator running during stop phases, a conventional starter battery will be driven flat within a few months. Add to that the fact that these vehicles routinely operate the battery at a partial state of charge (around 70% SoC), and a conventional battery is essentially guaranteed to fail prematurely, start-stop active or not.
SLI stands for Starting, Lighting, and Ignition. These batteries are engineered to deliver a large burst of current to crank an engine, then immediately accept a recharge from the alternator. They are optimized for shallow cycling — discharging only a small percentage of their capacity on each use — not for sustained deep discharge.
Discover's MIXTECH SLI batteries serve automotive, marine, RV, commercial truck, and work vehicle applications across multiple variants: EMX (standard starting), EFB (Enhanced Flooded Battery for start-stop systems), and EGM (for anti-idle and high-cycling demands).
Discover's patented MIXTECH technology incorporates a unique electrolyte mixing system built into the battery. During charging, the system actively circulates the electrolyte, preventing acid stratification — a primary cause of premature battery failure in flooded batteries. This results in more uniform plate utilization, higher CCA consistency, and longer service life compared to conventional flooded SLI batteries.
The EFB (Enhanced Flooded Battery) variant further adds carbon-enhanced negative plates for superior charge acceptance in start-stop vehicle applications, where the battery must rapidly recharge between engine restarts.
A standard aftermarket EFB outperforms a conventional flooded battery, but it still suffers from acid stratification over time, which degrades dynamic charge acceptance and shortens service life. Discover MIXTECH EFB is engineered to outperform both.
Versus a conventional flooded battery, MIXTECH EFB delivers more than 3x the micro-cycle life, tested to OEM standards. Where a conventional battery supports roughly 30,000 engine starts before replacement is needed, a MIXTECH EFB can sustain approximately 85,000 starts under comparable conditions.
Versus a standard replacement-market EFB, MIXTECH EFB delivers more than 2x the micro-cycle life under the same test standard. The carbon additives in the negative plates improve dynamic charge acceptance by up to 1.5x on their own. When combined with MIXTECH acid mixing, original charge acceptance is maintained at 3.5x greater than conventional or standard EFB batteries at the 6-month mark, the period when most batteries begin showing measurable stratification-related decline.
In practice, this means the start-stop system remains active and functional for longer over the battery's life, and the battery itself lasts significantly longer before needing replacement, reducing total cost of ownership despite a higher upfront price versus a conventional battery.
EFB stands for Enhanced Flooded Battery. It's an advanced flooded lead acid battery engineered specifically to meet the cycling, charge acceptance, and partial state of charge demands of modern start-stop vehicles. Conventional SLI batteries typically cannot handle these demands.
In a standard vehicle, the battery starts the engine once per trip and is then recharged continuously by the alternator for the rest of the drive. In a start-stop vehicle, the engine and the alternator shut off every time the vehicle comes to a stop. During that stop phase, the battery alone powers all vehicle electronics, climate control, entertainment, lighting, and safety systems. The moment the driver lifts off the brake or engages the clutch, the battery must crank the engine again, often from a partial state of charge, with only seconds before the next stop.
A conventional flooded battery fails rapidly under these conditions. Its plates and separators are not built for micro-cycling, and acid stratification accelerates sharply under repeated partial state of charge operation.
EFB batteries address this with enhanced plate alloys, carbon additives, and improved separator designs that sustain high dynamic charge acceptance and cycle durability. Discover MIXTECH EFB builds further on those advances with patented acid mixing technology that eliminates stratification entirely, maintaining original dynamic charge acceptance at a level 3.5x greater than conventional or standard EFB batteries after 6 months of real-world use.
Anti-idle batteries are required in applications, such as commercial trucks that are parked at loading docks or overnight, where drivers run cab accessories (HVAC, lighting, entertainment, refrigeration) with the engine off. This discharges the battery significantly before the engine is restarted.
Discover's MIXTECH EGM anti-idle batteries feature Enhanced Glass Mat (EGM) technology that bridges the performance gap between standard flooded and AGM batteries. They offer greatly improved cycling capability over standard SLI batteries, making them ideal for vehicles facing heavy accessory loads without continuous engine operation.
Yes. Discover's commercial MIXTECH lineup covers a wide range of heavy-duty applications including Class 6–8 trucks, transit buses, and work vehicles. The range includes:
- MIXTECH EMX Commercial Starting — Group 31 format for standard starting duty
- MIXTECH EFB Commercial High Power — For high electrical demand vehicles
- MIXTECH EGM Commercial Anti-Idle — For trucks with significant accessory loads at rest
- MIXTECH EMX Commercial Extended Cycle Life — High-CCA batteries for maximum starting reliability
Yes. Discover offers two dedicated marine and RV SLI variants within the MIXTECH family:
- MIXTECH EMX Marine RV Starting — A high-CCA starting battery purpose-built for marine engines and RV chassis. Incorporates MIXTECH electrolyte circulation for longer life and consistent starting performance.
- MIXTECH EFB Marine RV Dual Purpose — An Enhanced Flooded Battery designed to handle both engine starting and moderate house battery cycling. Ideal for smaller boats or RVs where a single battery must cover both roles.
These batteries are engineered to tolerate the vibration, humidity, and irregular charging patterns common in marine and RV environments — conditions that quickly shorten the life of automotive-spec starting batteries.
AGM/Gel Batteries
Yes, and using the wrong charging profile is one of the most common causes of premature AGM and Gel battery failure.
AGM batteries should be charged using a dedicated AGM profile, with a typical bulk/absorption voltage of 14.4–14.7 V and a float voltage of 13.5–13.8 V. Gel batteries require a lower charge voltage — typically 14.1 V maximum during absorption and 13.8 V float. Applying a standard flooded or AGM profile to a Gel battery will overcharge it, cause irreversible damage to the gel matrix, and significantly shorten service life. Never use a flooded battery setting for either chemistry.
Both AGM and Gel benefit from a multi-stage smart charger that progresses through bulk, absorption, and float stages automatically. Avoid chargers that apply a fixed voltage without a float stage, as continuous overcharging — even at a slightly elevated voltage — will gas a sealed VRLA battery and dry it out over time. Equalization mode must also be disabled for both AGM and Gel; unlike flooded batteries, VRLA batteries cannot vent excess gas and will be permanently damaged by equalization charging.
If you are unsure whether your charger is compatible, verify the output voltage at the battery terminals with a voltmeter rather than relying solely on the charger's display.
Both DRY CELL AGM and GEL batteries are sealed and do not require watering. The key difference is how they immobilize the electrolyte:
- AGM: The electrolyte is absorbed into a fiberglass mat separator, allowing for faster charge and discharge rates and superior cranking performance. Best suited for high-rate cycling applications.
- GEL: The electrolyte is mixed with silica to form a gel. Gel batteries tolerate deeper discharge cycles better than AGM and perform more consistently in high-temperature environments. They require a lower, more precise charge voltage.
Discover offers both as DRY CELL AGM (Traction and Dual Purpose) and GEL CELL (Traction) product lines
Yes. Because Discover DRY CELL AGM batteries are sealed and recombine gases internally during normal operation, they do not emit hydrogen under ordinary charging conditions. This makes them safe for installation in sealed or enclosed battery compartments — a significant advantage over flooded batteries in RV, marine, and motive power applications.
Under extreme overcharge conditions, the safety pressure valves will vent small amounts of gas, so ensure the installation location is not completely airtight.
Because AGM and GEL batteries are sealed, excess gas produced by overcharging cannot escape — it builds up pressure and, if severe enough, causes the battery case to bulge, warp, or rupture. Even moderate chronic overcharging causes water loss from the electrolyte that cannot be replaced, permanently reducing capacity and life.
Similarly, undercharging causes sulfation on the plates, which reduces capacity over time. Both AGM and GEL batteries require a charger with a controlled, regulated voltage output. Always use a charger explicitly rated as AGM or GEL compatible, and never use an unregulated trickle charger.
Note: GEL batteries require a lower maximum charge voltage than AGM batteries. Using an AGM charger profile on a GEL battery can damage it. Always match the charger profile to the battery type.
Not all AGM batteries are created equal. General-purpose or automotive AGM batteries are designed primarily for standby or shallow-cycle use — their plates are optimized for low-rate discharge and high CCA, not repeated deep cycling.
Discover's DRY CELL AGM Traction and GEL CELL Traction batteries are semi-traction / deep-cycle designs. They use thicker, denser positive plates with more active material, higher acid density, and plate alloys specifically chosen for resistance to corrosion under repeated deep discharge. This construction results in dramatically more usable cycles before capacity degrades — making them the appropriate choice for scissor lifts, floor scrubbers, forklifts, pallet jacks, AGVs, and other motive power equipment that cycles deeply every shift.
Discover DRY CELL AGM Traction batteries are a direct drop-in replacement for the flooded batteries commonly found in scissor lifts, boom lifts, and other mobile elevating work platforms (MEWPs). The advantages in this setting are significant:
- No watering or equalizing — eliminating the primary maintenance burden of flooded batteries on job sites
- No acid spill risk — critical in indoor environments where acid damage to floors or equipment is a concern
- Compatible with OEM onboard chargers — Discover's DRY CELL batteries are designed to work with the charging systems already installed in major MEWP brands
- Longer service life per cycle — reducing total cost of ownership versus flooded alternatives over the equipment's lifetime
Discover publishes a TCO calculator specifically for this switch at discoverbattery.com, and has OEM partnerships with major MEWP manufacturers including JLG, Skyjack, and Sinoboom.
Lithium Batteries
Discover's lithium batteries use Lithium Iron Phosphate (LiFePO₄) chemistry, which is widely regarded as the safest lithium chemistry available. LiFePO₄ cells are thermally stable and do not exhibit the thermal runaway risk associated with other lithium-ion chemistries.
Yes. Lithium BLUE was purpose-built for drop-in replacement of 12V, 24V, and 36V groupings of lead-acid batteries. It comes in two standard sizes — G24 and GC12 — with footprints the same or smaller than most deep-cycle lead-acid batteries used in RVs, caravans, and boats.
No special tools are required for the swap. If you can install a deep-cycle lead-acid battery, you can install Lithium BLUE.
Lithium BLUE requires a charger with a dedicated LiFePO₄ algorithm, or at minimum, one that can be programmed to match the charge voltages specified in the owner's manual. A charger set to a standard flooded or AGM profile will not charge Lithium BLUE correctly and may shorten its service life.
It depends on which Lithium battery you have:
Lithium BLUE (DLB): Lithium BLUE batteries include built-in Bluetooth connectivity. Download the Discover BLUE app from the App Store or Google Play to monitor real-time state of charge, voltage, current, temperature, status, and diagnostic reports directly from your mobile device.
Lithium PROFESSIONAL (DLP): Lithium PROFESSIONAL batteries are monitored via the BDI. The BDI connects to the battery's communication port and integrates with the LYNK ACCESS platform — compatible with the LYNK LITE or LYNK II gateways — to monitor real-time data, configure system settings, and download diagnostic logs.
Lithium MOBILE (DLM): Lithium MOBILE batteries use a dedicated Battery Monitor for state-of-charge display and system status. For expanded monitoring and diagnostic capability, the LYNK ACCESS platform is available via the LYNK LITE or LYNK II gateways.
LYNK ACCESS is Discover's proprietary PC-based software platform for configuring, monitoring, and troubleshooting Discover Lithium battery systems. It is aimed at installers, service technicians, and OEM engineers rather than everyday consumers. Key capabilities include:
- Real-time monitoring of state-of-charge, current, voltage, temperature, and active faults
- Configuration of CAN bus communication protocols (CANopen, Victron, SMA, Schneider Electric, Sol-Ark, RV-C, and others)
- Downloading diagnostic reports and battery log files
- Virtual battery simulation — allowing engineers to validate other devices against a digital battery signal without needing a physical battery present
- Firmware updates (on LITHIUM PROFESSIONAL batteries)
LYNK ACCESS requires a LYNK LITE or LYNK II communication gateway and runs on 64-bit Windows 10. It is compatible with Rackmount, Lithium MOTIVE, and LITHIUM PROFESSIONAL battery families.
Discover's lithium lineup covers three distinct use cases:
- LITHIUM BLUE — A consumer-oriented drop-in deep-cycle replacement for marine, RV, and caravan applications. Features built-in Bluetooth for monitoring via the Lithium BLUE app, a suitcase-style carry handle, field-serviceable fuse, and IP67 weatherproofing. Available in G24 and GC12 footprints at 12V, 24V, and 36V.
- LITHIUM PROFESSIONAL (DLP) — An advanced lithium system for professional motive power applications. Supports closed-loop communication via LYNK gateways, firmware updates, and CAN bus integration with chargers and inverters. Available in GC2 format at 12V through 48V.
- LITHIUM MOBILE — Targeted at industrial mobile power applications. Designed for integration into machine battery compartments where communication with onboard chargers and fleet management systems is required.
If you are unsure which fits your application, contact your local Discover distributor or the Discover sales team.
Yes. Discover offers heated variants of LITHIUM BLUE (model suffix "-H"), specifically the AES-B-GC12-12V-H and AES-B-G24-12V-H. These batteries include an integrated self-heating element that activates when the internal temperature drops near the charge cutoff threshold.
This matters because all LiFePO₄ batteries — regardless of brand — must not be charged when their internal temperature is below 0°C (32°F), as charging below freezing causes irreversible lithium plating on the anode. In cold climates or winter storage situations, the heated variant removes the need for the user to manually warm the battery before charging, making it a safer and more practical option for marine and RV users in northern regions.
Direct alternator charging of Discover lithium batteries is not recommended without additional hardware. Because LiFePO₄ batteries accept charge so efficiently, an alternator may run at or near peak output for extended periods — causing premature alternator failure. Additionally, if the BMS disconnects the battery to protect against overvoltage, the resulting voltage spike can damage the alternator and connected electronics.
The required solution is a lithium-compatible DC-to-DC converter installed between the alternator output and the lithium battery, which regulates both voltage and current. OEM integrators using Discover LITHIUM PROFESSIONAL batteries can leverage the LYNK II gateway to enable closed-loop communication between the BMS and a compatible charger or inverter-charger, dynamically optimizing charge rates. Refer to Discover's application note: Installing and Charging LITHIUM BLUE with an Alternator, available in the Resource Library.
Operation
The correct charger depends on your battery chemistry:
- Starting, Lighting, Ignition (SLI): Use a standard automotive charger set to a flooded or AGM profile to match your specific battery. Avoid overcharging.
- AGM/Gel: Use a charger with a dedicated AGM or Gel profile. AGM typically charges at 14.4–14.7 V; Gel at a slightly lower voltage (13.8–14.1 V). Never use a standard flooded setting as it will damage Gel cells.
- Lithium (LiFePO₄): Use a charger with a dedicated LiFePO₄ algorithm for best performance and cycle life. If using a lead-acid charger, confirm that the bulk and absorption voltages do not exceed those specified in your battery's owner's manual. A Gel profile is typically the closest lead-acid setting. Do not use a standard flooded algorithm.
- Flooded Deep Cycle: Use a multi-stage charger with bulk, absorption, and float stages. Equalization charging is periodically required to prevent sulphation. Consult your owner's manual for recommended frequency and voltage.
All battery chemistries are affected by temperature, but in different ways:
- SLI / Flooded: Cold temperatures reduce cranking capacity. Batteries rated at 0°C (32°F) may lose 20–30% CCA at -18°C (0°F). Heat accelerates water loss and plate corrosion. Keep batteries topped up with distilled water and fully charged in winter.
- AGM/Gel: Perform well across a broad range, but should not be charged below 0°C without appropriate low-temperature charging algorithms. Heat shortens service life more significantly than with flooded batteries.
- Lithium (LiFePO₄): Discharge is permitted down to -20°C (-4°F). Charging must only occur when the battery temperature is 0°C (32°F) or higher. Charging below freezing causes irreversible lithium plating. Discover Lithium batteries include a built-in BMS that protects against low-temperature charging.
Always refer to the operating temperature specifications in your product's owner's manual before use in extreme environments
No. Discover Lithium BLUE, Lithium MOBILE, and Lithium PROFESSIONAL batteries are designed for deep-cycle energy storage and are not rated for the high-current cranking loads required to start an engine. Using a lithium deep-cycle battery for engine starting will cause irreversible damage and will void your warranty.
For engine starting, use a Discover MIXTECH SLI starting battery appropriate for your vehicle type.
- SLI / Flooded: Signs include slow or failed cranking, a battery that no longer holds a full charge, low specific gravity readings even after a full charge cycle, or swollen/cracked case. Most automotive flooded batteries have a service life of 3–5 years under normal conditions. Discover MIXTECH batteries are designed for extended service life.
- AGM/Gel: Capacity loss exceeding 20% of rated capacity, repeated deep discharges below the minimum voltage, or a battery that fails a load test indicate replacement is needed. AGM deep-cycle batteries in high-cycle applications typically last 3–6 years depending on depth of discharge and temperature.
- Lithium (LiFePO₄): Discover Lithium batteries are rated for 2,000–4,000+ charge cycles depending on model and depth of discharge. When usable capacity drops below 80% of the rated capacity, the battery has reached end of useful life. The Discover BLUE app and LYNK ACCESS tool provide lifetime energy throughput data to help track battery health.
- Flooded Deep Cycle: Signs include inability to accept a charge, excessive water loss, sulphation (white deposits on plates), or a battery that cannot sustain load under normal conditions.
Storing My Battery
SLI:
Yes, provided the battery is fully charged before storage. A fully charged SLI flooded battery has a freezing point well below -60°C (-76°F), making cold storage safe. The danger is storing a discharged or partially charged battery. As the state of charge drops, the electrolyte becomes increasingly water-like and the freezing point rises sharply, reaching as high as -7°C (20°F) in a fully discharged battery. A frozen flooded battery will almost certainly not recover. Store SLI batteries fully charged, check the voltage every one to three months, and top up with a maintenance charge before the voltage drops below 12.4 V. If the battery does freeze, do not attempt to charge or jump it until it has fully thawed and returned to room temperature.
AGM:
Fully charged AGM and GEL VRLA batteries can be stored in colder temperatures than SLI batteries. Because the electrolyte is immobilized in glass mat separators rather than free liquid, AGM batteries are more resistant to cold-weather damage than flooded batteries — there is no free electrolyte to expand and crack the case. However, a discharged or partially charged AGM battery faces the same freezing risk as a flooded battery: as charge decreases, the electrolyte becomes more water-like and the freezing point rises. The self-discharge rate of a fully charged AGM battery is very low in cold storage conditions, meaning it will typically hold its charge for many months without needing a top-up. Do not attempt to charge an AGM battery that has frozen until its internal temperature has fully returned to room temperature.
Gel:
Fully charged Gel batteries can also be stored in sub-freezing temperatures, matching AGM in cold storage tolerance. Like AGM, Gel batteries must be fully charged before going into cold storage — a discharged Gel battery is vulnerable to freezing and will most likely not recover if it does freeze. Gel batteries are more temperature-sensitive than AGM when it comes to charging: do not charge a cold Gel battery until it has returned to room temperature, and be aware that Gel batteries require a lower maximum charge voltage than AGM — applying incorrect charge voltages at any temperature will permanently damage the gel matrix. As with AGM, cold temperatures slow Gel's already low self-discharge rate, so a fully charged Gel battery stored in the cold will typically require no maintenance charge for several months.
In all cases: charge fully before storage, do not charge while frozen, and bring the battery to room temperature before returning it to service.

The charger might have settings that prevent it from charging if certain thresholds have been exceeded or have not been met. We recommend using an external source to "jumpstart the battery" to bring it above the minimum threshold.
Some chargers draw energy from the already low battery before it can initiate a charge. This activity draws your battery even lower. We recommend using an external source to "jumpstart the battery" to bring it above the minimum threshold.
