Battery storage
BatteryBatterySelf-discharge,batteryChargingcapacity,ba ttery
Keep the battery pack between 0°C and +30°C. The lower the temperature at which
the batterie s are stored, the lower th e rate of self-discharge.
If you will be storing batteries for a lon ger period (longer than two months),
the b attery charge level should be approx. 30 %. To prevent exhaust ive
discharge which would permanently damage the battery, check the level
of charge of the battery a t regular intervals.
To be able to make use of the optimal charging capacity of the batteries, the battery
should be completely discharged and then fully recharged.
If you do not use the batteries for long periods, remove them from th e
notebook. N ever store the batteries in the device.
