The Battery Module
The battery module contains nickel-metal-hydride cells and has a built-in battery-
management system that controls charging and monitors discharge. This
provides a high capacity, low-weight battery system, which can be recharged at
any time. It is not possible for the user to over-charge or over discharge the
battery. For your own convenience it is best to charge it regularly to keep it
topped up, but leaving it in a discharged state will do no harm.
On the front of the battery module are two buttons and a 10-segment LED
display. To find the amount of charge in your battery module, whether
connected to your BITE 3 or separate, press the
Battery Condition
button.

The Battery State Indicator will light between 1 and 10 segments signifying between
10% and 100% charge respectively. After a few seconds this display will
automatically go out.
NOTE: The batteries are nickel-metal-hydride and if these are changed the
disposal of cells should be in accordance with local regulations.
Battery Charging
Please note - The battery should only be charged within the temperature range
32°F – 115°F (0°C to 45°C). Fast charging will not be allowed if the temperature
is below 10°C. Fast charging causes the temperature of the battery to rise. If the
temperature exceeds 115°F (45°C) the charging rate will be reduced
automatically.
To charge the battery, your battery module must be removed from the
instrument. Remove the module by pressing on the raised circular area of the
retaining clips and pull the top of the clip away from the instrument body. The
module now unplugs from the base of the instrument. Plug in the charger (J4) or
connect the optional 12 volt vehicle-type battery using the ‘cigarette lighter’ lead.
The LED "Battery State" indicator will light and show movement when the
battery is charging. The battery may be recharged before it has been fully
