The hazards of cadmium in lead-acid batteries
Lead-acid batteries have a relatively low energy density compared to modern rechargeable batteries. Despite this, their ability to supply high currents means that the cells have a relatively large power-to-weight ratio. Lead-acid battery capacity is 2V to 24V and is commonly seen as 2V, 6V, 12V, and 24V batteries. Its power density is 7 Wh/kg.

Lead-Acid Versus Nickel-Cadmium Batteries
Lining up lead-acid and nickel-cadmium we discover the following according to Technopedia: Nickel-cadmium batteries have great energy density, are more compact, and recycle longer. Both nickel-cadmium and deep-cycle lead-acid batteries can tolerate deep discharges. But lead-acid self-discharges at a rate of 6% per month, compared to NiCad''s 20%.
Tech Note | Battery Room Ventilation Requirements
Lead-Acid (LA) and Nickel Cadmium (NiCd) batteries vent hydrogen and oxygen when they are being charged. In the case of Valve-Regulated designs, the hydrogen is recombined with the oxygen within the battery back into water unless the gassing volume/pressure exceeds the opening setting of the pressure relief valve. Hence the name Valve-Regulated.
