something went wrong during the charging
process.
2. AC power to charger, but no battery
connected. Charger output leads are
unconnected, but charger is plugged into
the AC receptacle.
3. Battery voltage is below 3 Volts; the
charger does not recognize the battery
and will therefore not charge.
4. Reverse battery condition; output leads
are connected backward on the battery.
5. Overcurrent condition; Something is being
powered by the battery while it is charging.
