Information Article about 9 Volt NiMH (Nickel Metal Hydride) Rechargeable Batteries

This page offers fundamental information about 9 Volt NiMH (Nickel Metal Hydride) rechargeable batteries. As a public safety concern, the first declaration we make is:

Never use 9 volt NiMh rechargeable batteries in smoke detectors! Never use any type of rechargeable battery in a smoke detector. Because of the important role smoke detectors have in our lives, they require 9 volt batteries that are NOT rechargeable, and here's the reason: Standard 9 volt NiMh rechargeable batteries fully SELF-DISCHARGE after about two months, meaning there will be no more power in them to power the smoke detector should the need arise-the need being, a fire!

A smoke detector is not something you need, until you really need it and therefore you cannot take the chance that it will be rendered powerless because it has self-discharged. You want the peace of mind that comes from knowing your smoke detector battery ALWAYS has power to signal you in case of smoke or fire.

For smoke detectors, always use either 9 volt Lithium batteries or 9 volt Alkaline batteries (both of these are non-rechargeable) and, always check the battery itself every six months. Nothing replaces good old fashioned smoke detector and battery testing!

9 volt rechargeable batteries are offered in NiMH, NiCd and Lithium Ion (LI-Ion) chemistries. They are measured in mAh (which means: milliampere-hours) and the higher the mAh rating, the longer the run-time the battery will have.

Another very valued feature of 9 volt NiMH batteries, is that in NIMH chemistry, there exists no memory effect. This effect can be sustained in NICD batteries.

Memory effect is the result that happens when charging rechargeable batteries before they have been fully discharged, thereby reducing its total capacity). For those who wish to have worry-free, concern-free battery charging, without care or interest in what amount of power remains in the battery at time of charging, NIMH chemistry batteries are the popular choice.
