Battery storage
BatteryBatterySelf-discharge,batteryChargingcapacity,ba ttery
Keep the battery pack betwee n 0°C and +30°C. The lower th e temperature at which
the batteries are stored, the lower the rate of s elf-discharge.
If you will be storing batteries for a longer period (longer than two mon ths),
the battery charge level s hould be ap prox. 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 c ompletely discharged and then fully recharged.
If you do not use the batteries for long periods, remove them from the
Tablet PC. Never store the batteries in the device.
