What is a Lead-Acid Battery? Construction, Operation, and …
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.
And, everyone forgot to mention leakage. All energy storage devices (battery, capacitor, angry wife, whatever) leak the energy that is initially stored. Some faster leakage (angry wife), some slower leakage (battery). A lead acid battery can be expected to hold a charge WITH NO DRAW AT ALL for several weeks or months in the best cases.
