Owner’s Manual

Thank  you  for  purchasing  the  NoMEM  PRO  Battery  System.  Please  read  this  manual  carefully.  It 
contains important operating instructions for your NoMEM PRO Rechargeable Battery System. This 
PRO66 charger will quickly and efficiently charge all AA or AAA Nickel Metal-Hydride (NiMH) batteries. 
Some of the charger’s features are:

• Recharge 1 to 4 high capacity cells, up to 2300mAh, in approximately 1-hour. 
• Controlled by an intelligent microprocessor to supply the optimal charge current for prolonged battery 
   life and accelerated charging speed. 
• High speed charge and “trickle charge” modes 
• Automatic selection of the proper charge current for AA and AAA batteries
• Flexible power input allows you to use the PRO66 from home or overseas with its 100V-240V AC 
  Universal Power Supply, or on the road using the included 12V DC Cigarette Lighter Adapter. 
• LED indicators show each cell’s charging status
• Multiple built-in safety features

Charging Instructions

1. Remove & discard protection strip between batteries & contact before first use. 

* Specifications subject to change

2. Select the AC adapter or DC/Auto Cord adapter, depending on whether you are using the charger at 
home or in the car. Be aware that when using the DC/Auto cord, many cars do not supply power to the 
cigarette lighter while the key is in the off position. Plug the selected power adapter into the power 
source available, and plug the connector, at the end of the adapter cord, into the power input jack on 
the top of the charger unit. The red “Charge” indicator LED’s will begin flashing Red to show charging 
is taking place.

3.  When  the  LED’s  stop  flashing  and  are  on  continuously,  the  batteries  are  fully  charged,  and  the 
charger  is  in  “trickle  charge”  mode  to  maintain  the  batteries  at  full.  You  may  continue  to  leave  the 
batteries in the charger for several hours or even a day or two, but leaving the batteries in the charger 
continuously is not recommended. It is best to remove the battery as soon as it is practical after charge 
is complete. 

Note: 

The LED will be OFF for the following reasons:  No battery installed in that position. Battery is 

defective. Batteries are installed in reverse. Incompatible battery types are installed.

4. After removing the batteries from the charger, disconnect the DC power connector plug. Repeat the 
process from step 1 if you want to charge more batteries.

Note: This charger is designed to be operated at room temperature

Caution:

• Batteries are not charged as shipped. Must be charged prior to first use
• This charger is designed for indoor use only. Do not get damp or expose to rain
• This charger is intended to charge AA/AAA Nickel-metal-hydride rechargeable batteries only. 
   Attempting to charge any other types of batteries may cause personal injury and damage
• Do not mix AA/AAA, or Alkaline/NiMH, or batteries with different capacities
• Use only NoMEM PRO or other proper NiMH compatible charger to recharge NoMEM PRO batteries  
• Batteries may leak or explode causing personal injury if inserted improperly, disposed of in fire, mixed 
   with other battery types, or short circuited
• Remove the AC adaptor from AC mains when not in use
• Do not operate the charger if it has been subjected to shock or damage. Take it to a qualified service-
   man for repair. Not recommended for use by children
