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. For
a nickel metal hydride battery, it’s 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, it will deteriorate and 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.
