Information Article about AAA NiMH (Nickel Metal Hydride) Rechargeable Batteries

Because of their excellent value and performance, AAA NIMH rechargeable batteries are one of the most popular choices in rechargeable AAA battery size.  

Nickel Metal Hydride is the chemistry used to make the battery. These batteries don’t suffer from “memory effect” and are the ideal choice for high drain products such as digital cameras, mp3 players, GPS units and in many other commonly used devices, especially those applications that have LCD (Liquid Crystal Displays).

The term “Memory effect” means what happens when a battery’s total power has been lowered from recharging before first being fully drained. When recharging is done prior to when a battery’s been fully depleted of power, it will charge only what has been depleted, and “remember” this as the new total capacity of the battery. Nickel Metal Hydide rechargeable batteries don’t suffer this “memory effect”. They can be charged and recharged without regard for what voltage remains in them when they’re being recharged.

This makes it understandable why AAANiMh rechargeables are the popular choice for busy consumers all over now-a-days. NiCd (Nickel Cadmium) rechargeable batteries, on the other hand, can experience memory effect. NiCD batteries should ONLY be placed into a charger once they are completely “dead”.

All batteries are rated in mAh (milleampere hours). The higher the mAh rating that the battery has, (displayed in numbers), the longer it will last. This means longer RUN-TIME. AAA NiMh batteries are 1.2 volts in strength and are fully equivalent their AAA 1.5 volt Alkaline counterpart batteries.

There is a newer generation of AAA rechargeable NiMH batteries that offer a low self-discharge (LSD) feature. This technology’s great for the occasional user who may not consume the energy of the battery in the typical self-discharge time of roughly 30 - 40 days. Low self-discharge batteries hold their charge (keep their charge) for approximately 2 years. If you’d like to use Low Discharge rechargeable batteries, stock up on them when you find them at a competitive price and always, from a trusted and reliable supplier.

To the right of this information article, you’ll see our inventory of AAA NiMH rechargeable batteries. Our stock IS always fresh. That’s a guarantee!
