Overall Product Rankings
An Overview On Rechargeable AA Batteries
As the most popular battery size, AA batteries work with numerous items such as flashlights, handheld games, toys, digital cameras and TV remotes. This means it’s easy to go through a lot and have to order replacements. So, if you want to ultimately save money and contribute less waste, buying rechargeable AA batteries gives you the convenience of being able to simply recharge them whenever they run out of power. They also often come pre-charged and ready to use.
Rechargeable AA batteries come in two forms: nickel-cadmium (NiCAD) and nickel-metal hydride (NiMH). NiCAD batteries tend to cost less, allow for more charging cycles and charge more quickly, but they may not be the best option for high-drain electronics. NiMH batteries are more popular today since they can handle more powerful devices and last longer, but they do come at a higher price.
Regardless of which type you choose, you should check the capacity that is measured in milliamperes per hour (mAH). This indicates how much power the batteries have stored in them and ultimately how long your device will run, although performance will depend on the type of device powered. Most rechargeable AA batteries have an mAH of 2,000 to 2,800. While an mAH rating on the lower side can be fine for items like electronic toothbrushes or remotes, you’ll likely want a higher mAH for high-drain gadgets like digital cameras.
The lifespan and self-discharge rate are also important factors to look for when you’re shopping for rechargeable AA batteries. You’ll often see the lifespan mentioned as a certain number of charging cycles, and some brands list over 2,000 cycles before you’d need to replace the batteries. The self-discharge rate matters since your batteries’ capacity will drain simply from non-use, so looking for low self-discharge options is recommended.
You should also consider how many rechargeable AA batteries to get and whether you need accessories. It helps to get a large pack since the batteries have so many uses, and a storage container comes in handy. You’ll also need a compatible charger, which you can either buy alone or get a battery and charger set.
The Rechargeable AA Battery Buying Guide
- While you can use pre-charged batteries immediately, the downside is that some of their capacity may have depleted between the time the batteries were made and you purchased them. Therefore, it’s worth considering putting them in the charger so they can fully recharge first.
- You may find that your new rechargeable AA batteries don’t seem to last as long as advertised at first. That’s because it can take a few charging cycles before they have the best capacity.
- When you’re not using your rechargeable AA batteries, properly store them in either a plastic case or the original packaging they came in. Avoid letting them sit in extreme temperatures or areas with high humidity. Keep in mind that the batteries will discharge while in storage, so you should recharge them periodically so they’re ready for use in an emergency.
- For the best performance, it’s recommended not to mix rechargeable battery brands when you put batteries in a device. This also applies to battery chargers since damage could occur.
- Before putting AA batteries in a charger, always make sure they’re compatible and actually rechargeable. It can be easy to accidentally put a regular alkaline battery in a charger, and this can cause the battery to leak or even explode. So, avoid the dangers by checking first.
- Follow the manufacturer’s instructions closely for how to safely charge your AA batteries. Make sure that the charger’s contacts are clean and that you don’t see any damage to the unit or its plug. Insert the batteries firmly in the position indicated before you plug the charger in. Use any indicators on the charger that keep you informed on the charging status and possible errors. Lastly, unplug it as soon as the charging process completes.
- While rechargeable AA batteries are convenient, they don’t suit all use cases. For example, you’ll want to stick with traditional batteries for important safety equipment such as smoke detectors. Emergency equipment such as lamps and flashlights also benefit from traditional batteries that you can quickly swap without needing a charging source.
