Battery storage
BatteryBatterySelf-discharge,batteryChargingcapacity,ba ttery
Keep the battery pack between0°C / 32°F und 30°C / 86°F. The lower the temperature at
which the batteries are stored, the lower the rate o f self-discharge.
If you will be storing batteries for a longer period (longer than two months),
the battery charge level should be approx. 30 %. To prevent exhaustive
discharge which would permanently damage the battery, check the level
of charge of the battery at 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 the
notebook. N ever store the batteries in the device.
