BATTERIES DO NOT FULLY CHARGE
If the batteries are charged overnight, make sure the AC supply is not being switched-
off at night with other building items.
NEW BATTERIES
If batteries are new they sometimes need 20 to 30 charge/discharge cycles before they
charge normally due to a process called plate formation. With new batteries the 100%
LED may not light after a normal overnight charge. The batteries and charger are fine –
the machine should be used and charged each night. Within a few days to a week the
100% LED will go on during a normal overnight charge.
Brand new batteries are more easily damaged by heavy discharge than batteries that
are older. Try to avoid heavy discharge when new batteries are installed for at least the
first 20 charge cycles.
OLD BATTERIES
If batteries are old, check the battery condition following the battery supplier’s
instructions. Check for dead cells or Weak cells. If the charger case gets warm after
several hours of charging, the charger is probably good and the batteries bad.
Uninstalling the Charger
WARNING:
Disconnect from AC voltage before doing any service. When
plugged-in the AC wiring is an electric shock hazard. Disconnecting the DC
output connector near the batteries when the charger is ON may cause arcing and the
batteries to explode resulting in serious injury or death.
WARNING:
Risk of an electric shock causing serious injury or death. Do not
touch un-insulated parts of the charger wires, battery connector or battery
terminals. Be careful with tools as shock or arcing from shorting of electrical parts can
cause serious injury or death. Remove rings, watches, and jewelry to avoid arcing and
electric shock.
WARNING:
Do not disassemble the charger. Take it to a factory-authorized
service agent when service or repair is required. High voltages inside the charger
are an electric shock hazard and can result in serious injury or death.
