range.' If after 5 to 10 minutes of charging, the needle has not
startedto move toward lower amperages, unplug the charger and
discontinuecharging. If available, use a voltmeter and read the
voltage of the battery, if the voltage is under 12.0 volts for a 12
volt battery,or 6.0 volts for a 6 volt battery, plug the charger back
in and resume charging. If after another 15 to 20 minutes, the
ammeter has failed to move toward lower amperages, repeat the
voltmeter test. If the voltage has not increased, the battery needs
to be serviced or replaced.
