Rechargeable AA Batteries
Devices need AA batteries but laying hands on one when you most need it can be an undeniable burden. An alternative to classic AA batteries is to use rechargeable varieties. These batteries have a longer operating life than traditional batteries, as well as the extra help of being fully rechargeable.
Not all these batteries are standard, with some being notably better than others.
What does NiMH stand for?
The material is Nickel Metal Hydride (NiMH) which has benefits over other battery manufacture materials.
What does the battery memory mean?
Earlier batteries with other chemical arrangements were subject to a memory effect. This is when a battery must thoroughly deplete before recharge. The New Generation of NIMH batteries does not develop a memory effect and recharge at any moment during routine usage. If you are in doubt about battery charge level or condition, recharge it.
What does the mAh rating mean?
This is a rating of energy storage capacity mAh = “milli-ampere hours”. If you are comparing batteries to an AA with a 2000 mAh rating, it will have twice the capacity of a 1000 mAh rating.
What is the best application for NiMH batteries?
All applications with a high energy use and demand. The most common applications are digital cameras, PDAs, handheld games, portable music players, video devices and toys. If you are often buying alkaline batteries, then consider using rechargeable NiMH.
How often can I charge a NiMH battery?
Lower capacity rechargeable AA batteries -1700 up to 2000 mAh can be recharged up to 1000 times in overnight slow charge mode. 2100 to 2400 mAh rechargeable batteries can be recharged up to 600 to 800 times in overnight slow charge mode. The new higher capacity AA 2500 mAh rechargeable batteries have greater power capacity but can be recharged approx 500 times in overnight mode. Capacity improvement or quick charging will always decrease the number of cycles. Every cell available on the market above 2100 mAh will have below 1000 charge cycles.
The Criteria We Used for Our Evaluation of the Best Rechargeable AA Batteries
When it comes to batteries, we can't list a bunch of power cells. We've compiled a list of strict limits for our research and review. These limits were selected to give our audience the highest quality.
In the section below we'll go through each of our research limits, explaining why we've chosen each of them and informing you of their importance.
The following products were reviewed based on the following limits: Features, Pros & Cons, Price, Where to Buy, and Warranty.
