Introduction
Ordinary alkaline batteries can be charged with a current pulsed at a rate of 40 to 200 pulses per second, with an 80% duty cycle. Pulsed charging appears to reduce the risk of electrolyte — usually potassium hydroxide (KOH) — leakage. The charging current is usually very low to avoid rapid production of gasses that can rupture the cell. Cells that have leaked electrolyte are a safety hazard and unsuitable for reuse.
