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 sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation. 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).
High precision, integrated battery charge / discharge cycle test systems designed for lithium ion and other chemistries. Advanced features include regenerative discharge systems that recycles energy from the battery back into the channels in the system or to the grid.
Charging test and discharge test can be performed for lead-acid batteries, lithium batteries and other types of batteries. The maximum charge & discharge cycle index is 16 times, which can also be used as the aging equipment in battery production.
It is most important to measure the cells at the end of the discharge test in order to find the weak cells. It is also very important that the time OR the current during a discharge test is adjusted for the temperature of the battery. A cold battery will give less Ah than a warm one.
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.
