CHARGING INSTRUCTIONS
•
Plug charger power supply in to 110 VAC 60 Hz power source. The charger will have about 14
VDC across its + and H terminals with no battery in it. The plus terminal is labeled “+” and
negative terminal is labeled “H”.
•
Slide battery in to charger until the battery latches.
•
The single red LED will come on, when a battery pack is inserted in the charger and the charger
detects a good battery.
•
There are three charging levels: High rate: 500 mA, Top off: 40 mA and Trickle: 13 mA.
•
The charger automatically switches from “High rate” to “Top off” then “Trickle” charge by
measuring rate of change of temperature and time of charging.
•
If a discharged battery pack is too cold the LED will come on and it will trickle charge until the
pack warms up and then switch to high rate charge.
