which automatically detects
the voltage and charges the

This will happen if the battery
did not reach full charge

more power than the charger
can deliver in 24 hours. The

battery may also be faulty.
The charger has a relay that
turns the current on and off to
the battery.
The charger reached the
maximum voltage and is
reducing the current.
The charger detected an
over-temperature condition
and has reduced the current
to allow the unit to cool.

high from a partial charge.
