What is colloidal lead-acid battery?
Colloidal lead-acid battery is an improvement of common lead-acid battery with liquid electrolyte. It uses colloidal electrolyte to replace sulphuric acid electrolyte, which is better than ordinary battery in safety, charge storage, discharge performance and service life.
When should a lead acid battery be fully charged?
Periodically fully charging a lead–acid battery is essential to maintain capacity and usability. In traditional UPS or cyclic use, full recharge normally occurs following any discharge. This is in contrast to partial-state-of-charge use. In this use case, multiple shallow cycles of less than 50% of the battery capacity occur before a full charge.
How fast can a lead-acid battery charge?
Experiments on a 12 V 50 Ah Valve Regulated Lead Acid (VRLA) battery indicated the possibility of 100 % charge in about 6 h, however, with high gas evolution. As a result, the feasibility of multi-step constant current charging with rest time was established as a method for fast charging in lead-acid batteries.
What happens when a lead acid cell is charged?
Charging of lead–acid cell Discharging of a lead–acid cell The chemical reaction takes place at the electrodes during charging. On charge, the reactions are reversible. When cells reach the necessary charge and the electrodes are reconverted back to PbO 2 and Pb, the electrolyte's specific gravity rises as the sulfur concentration is enhanced.
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.
