Question about the relationship between lead-acid battery
In my textbook there is a typical discharge curve for a lead-acid battery of 100 Ah at C_10. According to this curve, if you discharge the battery at 10 A, the battery has a capacity of 100 Ah. If, however, you discharge the battery at 17.5 A, the battery only has a capacity of 90 Ah. If you discharge it at 5 A, the capacity is roughly 111 Ah.
6 FAQs about [Lead-acid battery charge and discharge conversion relationship]
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 does a lead-acid battery work?
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).

Do lead acid batteries lose water?
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. Other components of a battery system do not require maintenance as regularly, so water loss can be a significant problem. If the system is in a remote location, checking water loss can add to costs.
