FAQs about Lead-acid battery discharge balance

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.

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

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).

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 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.

What happens if a lead-acid battery fails?

In all the examples, two or more lead-acid batteries are connected in series. When a single lead-acid battery in the stack fails, all the lead-acid batteries in the series stack need to be replaced to maintain battery stack performance. This is a considerable expense.

What is the difference between a concentrating and a non-concentration solar collector?

In non-concentration collectors, the collector area and absorber area are the same. These collectors intercept solar radiation and absorb it without concentrating it. Concentrating collectors, however, have a larger area for intercepting solar radiation compared to the absorber area.

What are the different types of solar energy technologies?

Solar energy technologies are classified into two major categories, namely solar thermal and solar photovoltaic (PV) technologies.
