4. While charging, the display message will alternate
between “Charging” and “Bat=x.xV” (x.x is the present
battery voltage). The LED should be red in color when
charging.
5. When the battery is fully charged, the LED will change
from red to green and the message “Fully charged” will
appear on the display. After the battery is fully charged,
the unit will enter the “trickle charge” mode. In which,
the red LED will turn on for several seconds every
minute, to maintain the full charge.
A completely discharged MiniRAE 2000 monitor will be
charged to full capacity within 10 hours. The battery will
be drained slowly even if the monitor is turned off. If the
monitor has not been charged for 7-10 days, the battery
voltage will be low.
The factory-supplied battery is designed to last for 10
hours of normal operation (no alarm, no back light
condition), for a new battery under the best condition. As
the battery becomes older or is subject to adverse
conditions (such as cold ambient temperature), the battery
capacity will be reduced significantly.
