If refresh charging is necessary, the microcomputer
in the battery sends the information to the charger
and the refresh lamp on the charger flashes.
When recharging, if the refresh lamp on the char-
ger flashes, press the refresh switch to perform a
refresh charge cycle.
Refresh charging takes longer than normal charging.

(3) Battery's deterioration characteristics
All batteries are consumables. A battery gradually deteriorates and its capacity decreases
over time and with use.
The extent to which the capacity decreases by deterioration depends on the use conditions.
TIP
For a nickel metal hydride battery, its capacity will decrease to approximately 60%
of that of a new battery after 300 charge/discharge cycles, under normal use.
Even if a battery is not used, when it is stored over a long period of time, its capacity will
decrease.
When you are using multiple batteries, alternate between the batteries.
The extent of the deterioration of a nickel metal hydride battery can be checked after
charging is done, by pushing the indicator switch.
