Discover® Marine RV batteries outperform traditional Flooded, AGM, and GEL deep cycle batteries with exceptional dual purpose, starting and deep cycle performance. DRY CELL Marine RV batteries are tolerant of a wide ambient temperature range, vibration and Partial State of Charge (PSOC) operation. DRY CELL Marine RV batteries are safe, Non-spillable, maintenance-free, and are trusted by boat builders and recreational vehicle manufacturers.


Designed for Excellence

DRY CELL Marine/RV batteries are resilient, OEM proven, maintenance-free deep-cycle batteries, tolerant of Partial State of Charge operation and extreme ambient temperatures.

Product Features

Hydro Polymer

  • Organic capillary separator technology saturated with Hydro Polymer electrolytes delivers extra electrolyte volume
  • Resists dry-out and prevents thermal runaway
  • Maintains performance characteristics over operational life
  • Absorbed Glass Mat DRY CELL Technology. No free-flowing electrolyte

Enhanced Alloys

  • Thick plate construction with graphite enhanced plate alloys deliver maximum runtime over operational life.

Carbon Boost

  • Carbon additives increase duty cycle performance, battery charge acceptance and Partial State of Charge operation

Automatic Through-The-Partition Weld

  • Key industry models have improved product consistency and quality. Less wasted lead than manual welding process
  • Supports high current loads and lowers internal resistance

Polypropylene Case

  • Key industry models. Support high heat resistance and durability
  • Pressure relief valves with low open / close tolerance reduce water loss and extend cycle life
  • Integrated flame arrestors prevent fire and explosion
