Charging Lead-Acid Batteries: Best Practices and Techniques

Store Fully Charged: Always store lead-acid batteries fully charged. If a battery is stored in a partially discharged state, sulfation can occur, which will permanently reduce the battery''s capacity.

Characteristics of Lead Acid Batteries

Longer discharge times give higher battery capacities. The production and escape of hydrogen and oxygen gas from a battery cause water loss and water must be regularly replaced in lead acid batteries. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem.

Best Practices for Charging and Discharging Sealed Lead-Acid Batteries

There are two main charging techniques for sealed lead-acid batteries: float charging and fast charging. Float charging is a low-level continuous charge that keeps the battery at full capacity.

How to Calculate the time of Charging and Discharging of battery?

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 chemistry and the charge current. For NiMh, for example, this would typically be 10% of the Ah rating for 10 hours.
