Several battery manufacturers offer rechargeable AA batteries.
Electronics are a part of most people's everyday lives and a great deal of those electronics -- including remote controls, toys, clocks and digital cameras -- require batteries to operate. Instead of repeatedly purchasing packs of batteries, many consumers invest in rechargeable batteries. Not only do they eliminate waste and save money, they also hold a charge longer than regular batteries. Consumers have several choices when buying rechargeable AA batteries.
Energizer
Energizer's rechargeable batteries offer a longer charge than their nonrechargeable counterparts, powering a digital camera up to four times longer than regular batteries. You can recharge Energizer brand rechargeable batteries up to 150 times, and they will retain a full charge for up to six months when not in use.
Duracell
Duracell's rechargeable NiMH batteries are available in AA and AAA sizes. You can recharge them hundreds of times. They are specifically designed to be used in high-drain and frequently used devices, such as digital cameras or video cameras.
Rayovac
Rayovac rechargeable batteries come in two varieties: everyday use and platinum. You can charge everyday-use rechargeable batteries up to 500 times. Rayovac recommends them for high-drain devices, such as mobile media players and hand-held games. They can also take up to 300 digital pictures per charge.
Rayovac's platinum batteries retain their charge two to three times longer than most other rechargeable NiMH batteries. The extra power allows the platinum batteries to take 400 digital photos without recharging.
Kodak
Kodak's NiMH Pre-Charged Rechargeable Digital Camera Batteries are designed specifically for use in digital cameras and come fully charged. These rechargeable batteries last up to four times longer than regular rechargeable batteries.
Sony
Sony's rechargeable AA batteries last up to five times longer than regular alkaline batteries. Sony recommends them for use in hand-held gaming devices and digital cameras.
Sanyo
Sanyo's Enelope rechargeable batteries are one of the best-performing rechargeable batteries on the market. You can charge their AA batteries up to 1,000 times, receiving a full charge every time. The batteries also have a low discharge rate when not in use, retaining approximately 85 percent of their charge after one year.
