Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery might be employed to supply 25 A. If the battery rating is reduced to 100 Ah when supplying large currents, calculate how long it could be expected to supply 250 A. Under very cold conditions, the battery supplies only 60% of its normal rating.
