Need the highest capacity 9 volt rechargeable on the market today? The ultra-high capacity HiTech Li-Poly battery features double the power of regular alkalines and devastates the "never quite long enough" run-time found in typical NiCd and NiM rechargeable 9 Volt batteries. Boasting a capacity of 720 mAh, these batteries offer power to keep your devices running twice as long.
We highly recommend these batteries for wireless microphones, TENS units, guitar effect pedals, wireless guitar and bass systems, in-ear monitors and other devices that call for a 9-volt sized battery.
Given the technology behind these batteries, a standard NiMH/NiCd charger will NOT charge this battery. The only charger that will charge this battery is our 2 Bank 9 Volt Battery Charger.
Charging this in any other charger will cause fire or explosion. If this battery is charged in any other charger than the 2 Bank 9 Volt Battery Charger will void your warranty.
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.
