5. Make sure that the battery pack is fully recharged
To avoid an interruption of your operation due to power failure, check the battery voltage when
you start to use your PC in the field. See “Checking the battery level” (see Page 76) to check the
battery voltage level.
¡ Make sure that the battery pack is fully recharged

Approximate recharging times (when the PC’s power is off) :
80% recharging time 100% recharging time
Built-in battery pack Approximately 50 minutes Approximately 90 minutes
Both built-in battery pack and BN-LS12E standard battery pack Approximately 70 minutes Approximately 140 minutes
Both built-in battery pack and BN-LL22E large capacity battery pack Approximately 120 minutes Approximately 200 minutes
Cautions
•If the battery pack is discharged quickly even after its recharging, the battery service life has
expired. Replace it with a new one. (The built-in battery pack and CMOS backup cells are
service parts.)
•The standard recharging times listed above are typical values in an ambient temperature of
20°C to 25°C.
•It may take up to 1.5 times longer to recharge the battery pack if the PC is being used.
