12V Battery Charger Information
It is recommend to charge batteries at about
10% of their amp hour capacity. For example, an 80Ah deep
cycle battery should be changed at a rate of about 8A.
SLA, AGM and Gel batteries are traditionally charged at a
lower voltage than Flooded Lead acid batteries.
Different types of batteries require different
charging regimes. SLA, AGM
and Gel batteries are traditionally charged
at a lower voltage than Flooded Lead acid batteries.
Multi-stage chargers are recommended because
they adjust current and voltage according to the battery's
Multistage charging ensures batteries receive
optimum charging, but with minimal wear and tear, regulating
the voltage and current delivered to the batteries in three
automatic stages -
Bulk, Absorption, and Float:
1. Bulk - Replaces 70-80% of the battery’s state of
charge at the fastest possible rate.
2. Absorption - Replenishes the remaining 20-30% of charge,
bringing the battery to a full charge at a slow, safe rate.
3. Float - Voltage is reduced and held constant in order to
prevent damage and keep batteries at a full charge.
