Figure 4 : Chemical Action During Discharge 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 reduces the amount of acid in the electrolyte.
The batteries should be charged in a well-ventilated place so that gases and acid fumes are blown away. The lead-acid battery should never be left idle for a long time in discharged condition because the lead sulfate coating on both the positive and negative plates will form into hard crystals that will be difficult to break up on recharging.
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.
As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4). The return of acid to the electrolyte will reduce the sulphate in the plates and increase the specific gravity.
Over-discharging a lead-acid cell, like over-charging, can severely shorten the service life of the cell. The circuit moni-tors the discharging of the battery and disconnects all load from the battery when its voltage reaches a specified cutoff point.
The following are the indications which show whether the given lead-acid battery is fully charged or not. Voltage : During charging, the terminal voltage of a lead-acid cell When the terminal voltage of lead-acid battery rises to 2.5 V per cell, the battery is considered to be fully charged.

Freshening Charge – Lead-acid batteries will self-discharge from the day they are manufactured until they are put into service. As it is often several months before the battery is installed, it is important that a "freshening" charge be given before the battery exceeds its storage shelf life. For lead-antimony or selenium, this is usually 3 months, and for lead-calcium, 6 months. Some ...
