The Complete Guide to Buying AA Batteries

Many electronic devices require batteries, and AA batteries are one of the most common types of batteries. Many people think all AA batteries are the same but there are actually a variety of types. When purchasing batteries buyers should consider the price, how long they last, and whether or not they are rechargeable.


NiMH Batteries

These batteries consist of nickel and metal hydride. They are perfect for general use and fit in any type of device that accepts AA batteries. These work well for short usage, but they do not have a long shelf life or last very long while in use. They carry a 1.2-volt charge. NiMH batteries also come in a low-discharge form, which lasts a bit longer both on the shelf and during use.


Alkaline Batteries

Another very common and inexpensive option is an alkaline battery. Name brands such as Duracell and Energizer make alkaline batteries. There are also generic forms as well. Alkaline batteries are good for lower power devices like remote controls and children’s toys. A high drain alkaline battery works better for things that need power for a short amount of time, because they drain quickly. Also, alkaline batteries can leak if they stay in a device for too long.


Lithium Batteries

The most powerful battery is a lithium battery. They are great for items that need low power for an extended period of time, such as a smoke or carbon monoxide detector. The only downside to these batteries is that if they leak, which is rare, they can be toxic.


Carbon Zinc Chloride Batteries

For a heavy duty battery, a carbon zinc chloride battery is the best choice. This battery is ideal for use at high power for an extended period of time, and great for items like large children’s toys, cameras, or flashlights. They are stronger than other types of batteries at 1.65 volts, and have a much longer life.


Rechargeable Batteries

Nickel and alkaline batteries are also available as rechargeable batteries. Though the initial purchase of the batteries and the charger may be more expensive, consumers can save a great deal of money in the long run with this option. Simply, place them in the charger for several hours and then you have batteries set to use again.
