Refresh Charging the Nickel Metal Hydride Battery (JWB2)
A refresh charging is required on a nickel metal hydride battery to eliminate the memory effect.
When the battery is inserted to the charger, if the refresh lamp (orange) on the charger flashes, press the
refresh switch to perform a refresh charge cycle. (The refresh lamp flashes after every 20 to 30 charge cy-
cles. If the refresh lamp does not flash, it is not necessary to perform a refresh charge cycle.)
(1)
While the refresh lamp (orange) is flashing, press the refresh switch.
* The refresh lamp (orange) flashes only when re-
fresh charging is needed.
(2)
The refresh lamp (orange) changes from a flashing
to an "on" state, and the refresh charging starts.
In a refresh charging process, after all remaining electric-
ity has been discharged, the refresh lamp (orange) turns
off. The charge lamp (green) comes on and a normal charging process begins. The time it takes from the
start of refresh charging to the completion of normal charging is 3 – 19 hours.
• If the temperature of the battery rises during a refresh charge, the charge lamp (green) may flash and
the charging process may pause.
When the battery reaches an appropriate temperature, the charge lamp will change from a flashing to
an "on" state and charging will start automatically.
• If you perform a refresh recharge when the internal temperature of the battery is under 0°C or over
40°C, it may enter a standby mode as it goes into normal charging after discharging the remaining
electricity.
• Even if you fail to press the refresh switch, you can retry by momentarily removing the battery from the
charger, and then reinserting the battery to see the refresh charging alert.
• If you do not press the refresh switch while the refresh lamp (orange) is flashing, the flashing refresh
lamp will turn off after 1 minute. Then the charge lamp comes on and a normal charging process begins.
In this case, the refresh lamp flashes again the next time you charge the battery.
