Lead Acid

The Lead Acid Battery is a battery with electrodes of lead oxide and metallic lead that are separated by an electrolyte of sulphuric acid. Energy density 40-60 Wh/kg.

AGM (absorbent glass mat) Battery – the separators between the plates are replaced by a glass fibre mat soaked in electrolyte.

Cold cranking amps (CCA) – rating that measures a battery’s cranking power. It refers to the number of amps a 12-volt battery can deliver at 0°F for 30 seconds while maintaining a voltage of at least 7.2 volts.

Deep Cycle Battery – these batteries can be discharged to zero level and can still be recharged from that zero level back to 100% without any negative effect on the battery cells.

Gel Battery – great for extreme temperature, vibration, shock and over discharging better than any other Lead Acid battery

SLA (Sealed Lead Acid) Battery – sealed lead acid batteries are safer as they minimise electrolyte leakage.

VRLA (Valve Regulated Lead Acid) – safer as the hydrogen and oxygen produced in the cells largely recombine into water with minimal leakage.
