Battery Charging Output: 11.4V @ 100mA (each bay)
* Charging levels not actually specified, likely adapted based on battery chemistry and size.

Length: 6.0 cm
Width: 8.0 cm
Height: 2.3 cm
Weight w/o Batteries: 60g

Operating Temperature: 0°C ~ 40°C
Operating Humidity: 10% ~ 90%
Storage Conditions: 20°C ~ 80°C
Storage Humidity: < 85%

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).

Sample Charging Times:
160mAh - 1.8 hrs
180mAh - 2 hrs
200mAh - 2.2 hrs
220mAh - 2.5 hrs
