Car battery capacity chart.

I put together the following battery state of charge chart which indicates the state of charge percent as it relates to battery voltage or specific gravity. A 12 volt battery is capable of outputting 2 volts for each of the six cells. It is the energy a battery can deliver continuously for 20 hours at 80 f without falling below 10 5 volts. Amp hour and c20 battery capacity.

Automotive battery reserve capacity is a rating to give you an idea of how long the battery can be discharged at a rate of 25 amps while still maintaining at least 1 75 volts per cell or 10 5 total volts. With the ah chart you can see how much of a battery s capacity it retains after a given amount of time.
