OPERATION OF CHARGING STATION
3 - 4
The battery of the ToxiRAE unit will be drained slowly
even if the unit is turned off. If the unit has not been
charged for 4-5 days, the battery voltage will be low. The
charging circuit is designed to prevent over charging.
Therefore, it is good practice to always leave the unit in the
charger when it is not in use so that it is fully charged and
ready for immediate use.
The factory-supplied battery is designed to last for 12
hours of normal operation for a new battery under the best
condition. As the battery becomes older or is subject to
adverse conditions, the battery capacity will be reduced
significantly.
Charger Time Out
The battery charger has a built-in time out timer. After the
battery has been charged for 4 hours, it will automatically
switch to trickle charge mode and turn on the green LED to
prevent over charging the battery. It will not switch back
to charging mode unless the unit is lifted from the charger
and set down again to reset the timer. Since the charger
reverts to trickle mode, the ToxiRAE will not operate
indefinitely if left turned on in the charger, but should
operate 30-40% longer than when the battery is fully
charged.
