Equal charge and discharge of lead-acid batteries

Characteristics of Lead Acid Batteries

Constant current discharge curves for a 550 Ah lead acid battery at different discharge rates, with a limiting voltage of 1.85V per cell (Mack, 1979). Longer discharge times give higher battery capacities. Maintenance Requirements. 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.

6 FAQs about [Equal charge and discharge of lead-acid batteries]

What happens when a lead-acid battery is discharged?

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.

What happens when a lead-acid battery is charged in the reverse direction?

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.

How to charge a lead-acid battery?

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.

What is the chemical state of a fully charged battery?

The chemical state of a fully charged battery is depicted below. The primary components are: a positive plate comprised of lead dioxide (PbO2), a negative plate comprised of lead (Pb), and an aqueous solution comprised of sulphuric acid (H2SO4) and water (H2O).

How do you know if a lead-acid battery is fully charged?

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.

How does a lead-acid battery work?

Sulphuric acid is consumed and water is formed which reduces the specific gravity of electrolyte from 1.28 to 1.18. The terminal voltage of each battery cell falls to 1.8V. Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged.
