**==> picture [37 x 42] intentionally omitted <==**

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**_ 

**MH-C1090F Ten Bank Intelligent 2-Hour Charger for 9V NiMH Batteries** 

_**Thank you for purchasing the PowerEX battery charger. Read these instructions carefully and thoroughly before operating this unit. IMPORTANT SAFETY INSTRUCTIONS. READ AND SAVE THESE INSTRUCTIONS.**_ 

## **GENERAL PRECAUTIONS** 

- 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. 

## **FEATURES & SPECIFICATIONS** 

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 connectorend 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. 

## **WARNING: NEVER USE ALKALINE OR RECHARGEABLE ALKALINE BATTERIES.**
