  • Safety Timer - Charging stops at 5 hrs if complete charge has not been detected.
  • Delta V Cut Off - Detects when a Ni-MH battery has reached full charge.
  • Reverse Polarity and Short Circuit Protection - Physical reverse polarity protection.
  • Bad Battery Detection - Batteries that have been damaged during use or have reached end of life.
  • Ni-MH Compatibility - Will charge both 7.2V and 8.4V Ni-MH 9V batteries.
  • World Wide Power Compatibility - 100V - 240V AC input accepted.

Operation Instructions:

  • 1) Insert 1 or 2 Ni-MH 9V battery(ies) into the charger - ensure batteries are inserted in the correct direction for polarity.
  • 2) Plug the charger into a household electrical outlet. The LED(s) will light up in red to beginning of operation.
  • 3) Monitor the batteries, remove a battery when the LED for that bay is flashing red or is constant green.

LED Indications:

  • Off - Charger not plugged in or no battery in the bay.
  • Red, Constant - Battery in that bay is charging.
  • Green, Constant - Battery in that bay has completed charge (either by Delta V detection or 5 hr timer).
  • Red, Flashing - Battery in that bay has an issue, unplug the charger and remove the battery.
  • Possible Issues:
  • - Short Circuit : Check the bay and battery for debris connecting the terminal points. Check the battery for damage.
  • - Reverse Polarity : Check that the terminal points of the battery are connected to the terminal points in the charger correctly. The narrow terminal goes inside the wider terminal of the other component.
  • - Faulty Battery : The battery may have been over-discharged or other wise internally damaged from use. The battery may have also reached end of life (usually over 300 cycles, potentially up to 1000 cycles).
