Self-Discharge

Rechargeable batteries discharge when left on the shelf (whether in a com-
puter or not). Thus, rechargeable batteries stored for as little as a month
need to be recharged before using. If an external charger cannot be used
and the battery must be installed in a computer, allow an extra three hours of
charging before using the computer without an attached charge source.
Sometimes it takes two or more charge-and-discharge cycles to bring a
stored battery back to normal capacity.

Temperature Extremes

If the computer is kept at room temperature, a dead battery charges in as
little as three hours. If the computer is kept at extreme temperatures, such
as above 104
computer continues to operate from the charge source as long as it is avail-
able.
If this becomes a problem, an external battery pack charger may have to be
purchased to keep spare batteries charged. Contact Norand Customer Sup-
port Center for more information.

Computer Beeps

"Beeps" are usually referring to the memory power-on self-test after the
reset switch is pressed. Listen for beeps when pressing the [ON] key to
wake up the computer. One or three beeps indicate a low main battery. If
the computer beeps but does not power up, place the computer on charge. A
good computer, with a low main battery, powers up when placed on charge.
Allow this computer to remain on charge for a few minutes. The main bat-
tery pack fully charges with a fast charge of 2 1/2 hours; or a trickle charge
of 10- -14 hours. The computer will determine whether to do a fast charge or
a trickle charge.

NOTE: Do not disconnect the backup battery until the computer powers up from the main
battery or from the charge; or unless the computer data is not critical.
