Discharge and Charging of Lead-Acid Battery
When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby …
How to Calculate the time of Charging and Discharging …
Discharge time is basically the Ah or mAh rating divided by the current. So for a 2200mAh battery with a load that draws 300mA you have: $frac{2.2}{0.3} = 7.3 hours$ * The charge time depends on the battery …
How do I calculate the self discharge rate of a lead …
Standard lead-acid cells have a low self-discharge, about 5% per month, so continuously monitoring makes little sense. To measure this I would take a reading with a DMM every few days, and you may need to take readings over …
Discharge and Charging of Lead-Acid Battery
