You notice battery cells become sulphated when the battery voltage can be driven high and battery receives no current. Typically a healthy and slightly discharged 12V 70Ah battery drops to 15-20 Amps after a few minutes at 14.4V chharging. When sulphated You can apply 15-30V and barely no current flows at all. Then you are in trouble.
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.
