If depleted to 50% as recommended, a 100Ah 12 volt deep-cycle lead-acid battery can operate a 100W continuous DC load for 6 hours. With a 50 percent Depth of Discharge, a 100Ah 12 volt lead-acid deep-cycle battery could power a 100W rated AC food mixer for 7 hours.

## How long will a 100Ah battery run a 1000w inverter?

A fully charged 1000 watt inverter would operate for 34 minutes on a 12 volt 100Ah deep-cycle battery with a typical depth of drain of 50%. The average pure sine wave inverter efficiency is 95 percent in this estimate.

## How long will a 100Ah deep-cycle battery last?

The reserve capacity of 12V 100Ah general-purpose lead-acid batteries is normally approximately 170-190 minutes, whereas premium lead-acid batteries have a reserve capacity of 190-220 minutes. The 12V 100Ah deep-cycle lithium batteries’ reserve capacity is generally approximately 240 minutes; these batteries can produce 25 amps for 4 hours.
