Important note about the voltage of this battery:
Rechargeable batteries, like this 9V-size Lithium Ion battery, are rated at a lower voltage than their Alkaline-based alternatives. If your application absolutely requires a full 9 volts to operate, rechargeable batteries may not work for you. Please view the datasheet or give us a call at 1-800-405-2121 for further information.
If your device has a charge indicator, this battery will most likely not show a "full" charge when installed. These indicators are calibrated for alkaline 9 volt batteries, which, by design, have a higher initial voltage level than a fully charged rechargeable battery. The battery will work, but the indicator will display inaccurate results.
