Works ONLY for products that operate on four, 1.25 Volt Rechargeable Batteries (Nickel Metal Hydride NiMH or Nickel Cadmium NiCad). May not work in devices that are designed only for Alkaline batteries as they are a slightly higher voltage (1.5 Volts each x 4 = 6 Volts). Not compatible with high current devices like photo flashes or devices with motors and solenoids.

Our AA Battery Eliminators fit into the battery compartment of your device the same way as a standard AA sized battery. Our AA Active Cell receives power from a thin flat cable that is run under your battery compartment cover. You may have to file a small slot in the battery cover for a perfect fit using a file (included). Our AA Dummy Cells fit into the remaining battery spaces in your battery compartment and complete the circuit which powers your device. The appropriate voltage for the number of cells being replaced is provided by our power unit. Please purchase a Battery Eliminator that matches the total number of cells in your device to ensure the proper voltage is delivered. Choose an AC Source model for use with either US/Canada (120VAC) or International (100-240VAC 50/60Hz) wall current. Choose a DC Source model for use in a vehicle or other 12VDC - 28VDC portable power source. Choose a USB power source (~5VDC up to 500 mA) for use with a USB port on a phone charger, computer, portable battery pack, or any other USB port device.
