MAINTENANCE FOR AREARAE
6-2
6.1 Battery Replacement
When the display shows a flashing message “Bat,” the battery
requires recharging. The battery may be replaced in the field
(in area known to be non-hazardous) if required. It is
recommended to recharge the AreaRAE or AreaRAE Gamma
monitor upon returning from fieldwork. A fully charged battery
powers an AreaRAE for up to 24 hours of continuous
operation. The charging time is less than 10 hours for a fully
discharged battery. The built-in charging circuit is controlled by
two-step constant voltage/constant current charging to prevent
overcharging.
WARNING
To reduce the risk of ignition of hazardous atmospheres,
recharge battery only in area known to be non-hazardous.
Remove and replace battery only in area’s known to be non-
hazardous.
