2A AND 10A BATTERY CHARGERS
There are two types of battery chargers. A 2 Amp bat-
tery charger and a 10 Amp battery charger.
The 2 Amp battery charger is a "float" type charger. A
"float" type charger will charge the battery at its maxi-
mum output current rating until the battery voltage
reaches a "float" voltage and then the charge current
will decrease to maintain the battery at that "float"
voltage.
The 10 Amp battery charger is an "equalize" type
charger. An "equalize" type charger will charge the
battery at its maximum output current rating until
the battery voltage reaches an "equalize" voltage and
then the charge current will decrease to maintain the
battery at a lower "float" voltage.
