Nickel Metal Hydride Batteries (NiMH)

These small, powerful and lightweight batteries can power some of our smaller products for an extended duration. These batteries are rechargeable for up to hundreds of cycles if used properly. See explaination below to learn how to get the longest life and greatest power delivery from your NiMH battery.

 Battery Life

Nickel Metal Hydride (NiMH) batteries are rechargeable and can be recharged for hundreds of cycles. Your battery life will depend on how you properly care for your battery. Gerbing's does not offer any warranty on the lifespan of your NiMH battery.

To break in a new battery properly, we recommend charging and discharging the battery fully 4 to 6 times to enable the battery to reach its full rated capacity.

NiMH batteries have no memory effect, but the memory is held in the charger. Over a series of charges, the charger remembers the charge capacity required to bring the battery to a full charge. If you run your battery for only 1 hour, then recharge, the memory will adjust to provide 1 hour of charge to recharge. This is not enough! To prevent this, condition your battery and charger by charging the battery for 10 hours and then draining the battery until your heated product no longer is providing heat. Be sure to always disconnect the battery from your product when it stops providing heat.

To increase the longevity of your batteries, don't leave them dormant for extended periods of time. We recommend that you completely charge and discharge at least every 2 to 3 weeks. Batteries left idle for extended periods of time self-discharge at a rate of 2% per day. Just remember to charge your batteries again before use.

Our NiMH charger charges overnight and includes built-in overcharge protection. The charger also has an indicator light so you know when the battery is completely charged.

You can also attach your NiMH battery to our battery belt. Wear your lightweight battery hands-free where ever you go!
