Learning About Rechargeable AA Batteries and More

Your electronic devices require power, and there's a wide variety of single-use and rechargeable AA batteries and other batteries available. While the many choices of batteries can seem overwhelming, picking the perfect type is easy with a little knowledge about your device, and the different types of batteries and chargers.

Single-Use Batteries

Single-use batteries have a long shelf life, but you must dispose of them when you've exhausted their use. Alkaline AA batteries, along with other sizes, are the most popular single-use batteries. Lithium batteries have a longer shelf life, last longer while in use, are lighter in weight, and are more resistant to extreme temperatures. Always make sure to consult the device's instructions to make sure your device can handle lithium batteries, as higher voltages may harm some devices. Some devices even use button and coin cell batteries, so always make sure to confirm exactly what battery type you need.

Choosing Rechargeable Batteries

Rechargeable batteries save you money over time, and are more environmentally friendly, as you can use them repeatedly. Nickel-metal hydride (NiMH) options hold their charges when unused for long periods, but lithium-ion batteries power devices longer. Rechargeable lithium-ion batteries are the most common choice for digital cameras, but for professional cameras, consider external camera battery packs and cables and AC adapters and DC couplers.

How to Pick a Battery Charger

If you choose rechargeables, you'll also need a battery charger that works with the type of batteries you choose, whether NiMH or lithium-ion. Some chargers work with a variety of sizes of batteries, although it's best to charge only one size at a time. Some charge your batteries much faster than others, and offer features such as smart charging, which ensures that batteries don't undercharge or overcharge, helping the batteries to perform better and last longer.
