How do I choose a rechargeable battery? It’s a simple question with an often complicated answer. When shopping for rechargeable batteries, you’re likely to encounter a number of different chemistries, brands and product lines. Wading through all of that can be a bit of a chore, which is why we’re here to help. Our handy guide will help break down the essentials you need to know when shopping for rechargeable AA and AAA batteries.
This will depend largely on the application. Rechargeable batteries work best in applications which operate at a constant discharge and have long run times. Things like toys, remote controls and video game controllers work great with rechargeable batteries.
For low drain devices such as clocks, smoke alarms and portable lights, you’re better off using alkaline batteries. The reason for this is that alkaline batteries tend to die quicker. A rechargeable battery will last longer at a lower voltage toward the end of its life, which can result in performance issues for things like clocks and lights.
Before we get started, we need to define a few terms first.
The two types of rechargeable AA/AAA battery chemistries available at Batteries Plus are nickel-cadmium (NiCd) and nickel-metal hydride (NiMH). Here is a breakdown of their pros and cons.
When purchasing rechargeable batteries, it’s a good idea to take a look at the owner’s manual of the application you’re going to be using it in. Many devices have specific battery chemistry requirements. If your device accepts both NiCd and NiMH batteries, it will likely mention this in the user’s manual.
This will depend largely on what you’re using it for. A NiCd battery will give you a greater number of charging cycles, however, they will need to be recharged sooner than using an NiMH option. If you’re looking for a source of reliable power for everyday applications, our X2Power NiMH batteries are a great choice. Both the X2Power AA and X2Power AAA batteries can be recharged hundreds of times and last longer per charge than their NiCd counterparts.
When shopping for a battery charger, you need to make sure that the charger you buy is compatible with the chemistry of your battery. That means using an NiCd charger for NiCd batteries and using an NiMH charger for NiMH batteries. Batteries Plus offers a number of NiMH chargers. We recommend the Nuon NiMH 4 Hour Charger. It charges NiMH batteries in four hours and comes with a smart charging feature that prevents them from overcharging. Plus, you can charge four batteries at once.
Batteries Plus carries rechargeable batteries in a number of sizes and voltages, including AA, AAA, C, D, 9V and more. You’ll also find an enormous selection of alkaline batteries from trusted brands like Duracell® and Rayovac®. Not sure what to do with your old batteries? Bring them to your nearest Batteries Plus and have them recycled. Want to learn more about rechargeable batteries?
