How long can I discharge my Discover battery?

How long your Discover battery can be discharged depends upon its capacity and the amount of power consumed by the equipment connected to it. Generally, the faster you discharge the battery, the less power it will deliver due to the Peukert Effect. Conversely, the slower you discharge it, the more power it will deliver. A 100-amp hour battery supplies a current of 5 amps for 20 hours, during which time the battery's voltage remains above 1.75 volts per cell (10.5 volts for a 12-volt battery). If the same battery is discharged at 100 amps, the battery will only run for approximately 45 minutes before the voltage drops to 1.75 volts per cell, delivering only 75-amp hours of total power. Connecting a load of only 1.2 amps to the same battery until it reaches a cell voltage of 1.75 will result in the battery delivering 120 amps of usable power. This is all the result of the Peukert effect. Discover Industrial Semi-traction deep cycle Dry Cell AGM and GELL batteries are electrochemically designed to deliver 80% of published AH capacity above 1.9 volts per cell, thereby ensuring that a 100 amp hour Discover Semi-traction Dry Cell AGM or GELL battery will deliver a higher % of the 100AH available than general purpose Deep Cycle batteries when discharged at higher rates resulting in an improved Peukert coefficient.
