nOTE: CHARGInG RATES VARY
AnD DEpEnD On THE:
The battery capacity rating (in minutes):
The higher the rate... the longer the charging
time required.
The degree of discharge:
A fully discharged battery requires 2 x’s as
much charging as 1/2 charged battery.
The battery condition and age:
An old battery and/or one in poor condition
requires more charging time.
The electrolytic temperature:
The colder the temperature...the longer the
charging time required.
CAuTIOn: Exceeding recommended
charging rates can damage battery plates
and generate potentially explosive gases.
