Lead-acid battery desulfator

Sulphation is a common problem in lead-acid batteries which usually happens when the battery remains idle for a long period. The sulphuric acid inside the battery react with the electrodes to form sulphate crystals that eventually deposit on the electrodes resulting into sufficient reduction in the efficiency. It has been found from research that the deposited layer of sulphate crystals may be broken down by applying high current pulses to the terminals of the battery. This instructabledescribes a desulfator circuit using 555 timer IC to reverse this process and rejuvenate the battery to like new condition.
