How Long Will A 12v Battery Last Calculator. How long does a deep cycle battery last. 12 volt deep-cycle lead-acid available capacity 100Ah x 50 50Ah.
This is the total energy storage the battery can hold in amp-hours. If you intend to power the power inverters using AGM or Gel-Cell lead-acid batteries for at least 30 minutes rule of thumb is to use 12V batteries with the capacity in Amp-hours 10x lesser than the power of the inverter given in watts. If you open the advanced mode of this battery capacity calculator you will be able to compute three other parameters of a battery.
The following is an example of how to calculate a total battery run time.
Battery capacity in milliampere-hours divided by load current in milliamperes. Battery capacity calculator. The most common formula used to determine battery life is. Run-time 06 hours x 95 o57 hours 342 minutes.
