These procedures vary depending on the type of battery cells, such as lead-antimony and lead-calcium batteries. Let’s delve into the details of these initial charging processes: Wet Cells and Periodic Monitoring

How to check the state of charge of a battery?

It is essential to periodically monitor the state-of-charge of wet cells by measuring the specific gravity. If there is a 25 point (0.025) decrease in specific gravity, a freshening charge should be applied to maintain the battery’s performance.

How do you charge a lead-calcium battery?

The initial charge for lead-calcium batteries should be performed using an initial charge voltage per cell (VPC) corresponding to the nominal specific gravity of the battery. The duration of the initial charge is not fixed and continues until the lowest individual cell voltage ceases to rise.

Do I need a supplementary charge before installing a battery?

Measure the battery open circuit terminal voltage which should be > 2.1 volts/cell (12.6 volts for a 6 cell battery).
