Lead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions.

Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery might be employed to supply 25 A. If the battery rating is reduced to 100 Ah when supplying large currents, calculate how long it could be expected to supply 250 A. Under very cold conditions, the battery supplies only 60% of its normal rating.

A SLA (Sealed Lead Acid) battery can generally sit on a shelf at room temperature with no charging for up to a year when at full capacity, but is not recommended. Sealed Lead Acid batteries should be charged at least every 6 – 9 months. A sealed lead acid battery generally discharges 3% every month. Sulfation of SLA Batteries
Red lead (Pb 3 O 4), also known as minimum, trileadtetroxide or lead orthoplumbate, is normally a fine, dry, brilliant red colored solid usually used in the form of a powder can also be wetted and agglomerated into pellets. In contrast to other lead oxides, the lead atoms in red lead occur in two different oxidation states, i.e. Pb(II) and Pb(IV).
