Thank you for purchasing the Powerex MH-C1090F Pro 10-Bank Rapid Charger.
Read these instructions carefully and thoroughly before operating this unit. IMPORTANT SAFETY INSTRUCTIONS. READ AND SAVE THESE INSTRUCTIONS.


  • Do not charge battery chemistry other than NiMH.
  • When not using with Maha 9V batteries, verify batteries can accept 90mA quick charge. Batteries incapable of accepting a rapid charge may explode and result in fire.
  • Always insert the batteries so that the positive end faces up (see illustration under “Charging Instruction”).
  • Do not expose the unit to rain or moisture due to risk of fire.
  • For indoor use only.
  • Do not operate the charger if it appears damaged in any way.
  • Always use the supplied AC adapter.
  • Do not allow the battery terminals to become shorted.
  • To reduce the risk of damage to the AC power adapter, always pull by connector


  • Rapid charge one to ten 9V NiMH batteries in around two hours.
  • FLEX pulse charging conditions and enhances battery performance during charging.
  • Microprocessor controlled rapid charge with automatic trickle charge.
  • Compatible with 7.2V, 8.4V and 9.6V batteries.

Rapid Charge Current:  70-90mA

Trickle Charge Current:  10mA

Charging Cell Configuration:  One to Ten 9V batteries (7.2V, 8.4V or 9.6V)

Microprocessor:  Ten independent circuit, capable of charging batteries simultaneously. – deltaV based.

Microprocessor:  120-160 minutes*

Input Voltage:  13.5VDC 1000mA

* Charge time will vary depending upon the brand, capacity, and condition of batteries being charged.


For new NiMH batteries, it is necessary to cycle them three to five times before they reach peak performance. Battery cycling can be achieved by using the batteries completely and recharging them.

When using at home / office
1. Plug in the supplied AC power adapter into an outlet matching the input requirement indicated on the label,without the charger attached.

2. Connect the charger (without batteries installed) to the connector-end of the AC power adapter.

3. Place the batteries into the charger. You may put 1 to 10 batteries in the charger. Use only 7.2V, 8.4V or 9.6V NiMH batteries. You may mix different voltage of batteries in the charger. See illustration below for proper polarity and insertion instruction.

It is possible for certain batteries to be charged slightly slower than others. It is normal for certain banks to finish faster or slower than others.

The following are the meanings for each color indicator condition:

RED:  Rapid Charging

GREEN:  Charge Completed

FLASHING RED:  Bad Battery

4. When the lights turn green, the batteries are ready to be used.
