Maha Powerex MHR84VP 9V Ni-MH Battery

The Maha Powerex MHR84VP is a single 9V nickel-metal hydride rechargeable cell rated at 300 mAh with a minimum capacity of 270 mAh. It arrives pre-charged and ready for immediate use in devices that require a 9V format. The 8.4 V nominal voltage suits compatible electronics such as wireless microphones, medical instruments or test equipment. Users who need a replaceable power source for occasional or regular duty can rely on this chemistry.

Replacing disposable 9V alkaline cells

This rechargeable battery replaces single-use 9V alkaline cells in the same form factor. The jump is worth it when the device is used frequently enough to benefit from hundreds of recharge cycles and the low self-discharge characteristic that retains up to 85 % of charge after one year of storage. It is not for buyers who need a higher capacity than 300 mAh or a different voltage platform for their application.

Check device voltage and charger compatibility

Before ordering, verify that the equipment operates correctly at the 8.4 V nominal voltage of a Ni-MH 9V cell. Confirm that you have a charger designed for 9V nickel-metal hydride chemistry to achieve the stated cycle life. The battery is supplied as a 1-pack, so plan for the quantity your setup requires.

Questions about this item

What device compartment fits the 9V Ni-MH form factor of the MHR84VP?

The MHR84VP uses the standard 9V rectangular size, so it fits any device compartment designed for a 9V battery such as smoke alarms, wireless microphones or multimeters.

How do I charge the pre-charged 300mAh cell for the first time, and what step is often missed?

Insert the battery into a compatible Ni-MH charger observing the 8.4V polarity markings; the step users miss is selecting the Ni-MH charge mode instead of a generic or lithium setting.

When will the 300mAh capacity drop below the 270mAh minimum after repeated recharging?

The cell is rated for hundreds of recharge cycles; capacity typically stays above the 270mAh minimum for several hundred cycles before gradual decline requires replacement.
