2.3 Battery charging
The external battery can be unclipped from the scanner and charged in the standalone charger.
The battery LED will flash slowly while charging with the colour indicating the current state of charge
(Red = less than 25%, Amber = 25% – 75%, Green = more than 75%. Once fully charged the LED will
either show continuous green or a rapid flashing green.
All batteries will be charged within five hours, but will not be damaged by continued charging.
The NiMH batteries in the battery pack are paired with charge management circuits to give several
hundred recharge cycles. While the battery is in a good condition and is fully charged, the scanner will
run for the duration below. This time will vary depending on the display option used.

Electrical connection to the power pack is through the gold pads on battery and scanner. Power pack
output is protected with a resetting fuse but care should be taken to prevent short circuiting the gold
connector pins and pads. Battery metering relies on internal calculation. Repeated cycling without
complete discharge or charge completion will result in increasingly inaccurate battery level indication.
For peak performance, and for most accurate battery meter indication, batteries should occasionally
be run flat followed by a complete charge cycle.
Occasionally (every ten cycles, or once a fortnight) discharge until the scanner automatically switches
off, followed by a complete charge in one go (preferably from the mains supply).
