SECTION 1 General Information
6400 Hand-Held Computer User’s Guide 1-21
A fully charged battery pack, left outside of a charger or
your computer, self discharges in about 20 days. It is best to
take batteries directly from the charging device and install
them into your computer.
Your battery packs are rated for 500 full charge/discharge
cycles after which they have 50% of their original capacity.
The main and backup batteries will not charge below 32_F
(0_C) and above 104_F(40_C). The battery life of the cells is
reduced when running in cold temperatures.
EXAMPLE: Your computer should be used only two shifts a day in a below 0_C
environment to allow eight hours for the internal backup battery to
recharge in room temperature.
It is always a good idea to check the capacity of your bat-
tery pack before inserting it into your computer, and charge
accordingly. Refer to Measuring Battery Pack Charge
Level on page 2-7 for instructions.
