Which battery lasts the longest

When you need rechargeable batteries you can trust, most Amazon reviewers turn to Duracell.

These batteries recharge up to times within hours and can power batteries at once. The bonus is they can last up to 10 years in storage.

Promising review: I'd resisted buying rechargeable batteries because I didn't want to make the investment and because I didn't know if they'd last as long as non-rechargeables. I'm a total convert now. The charger works fast and the batteries appear to be holding their charge really well. Now, I can have as many as I need in my devices and plenty more on standby. If you need AAA batteries, turn to Rayovac.

These rechargeable Alkaline batteries can hold power for up to a year in storage and are perfect for digital cameras. They come fully charged and are guaranteed to last up to 5 years. Promising review: I highly recommend these. I've used them countless times on my various devices and have saved a ton of money by recharging them. I also carry a USB charger that I plug into my laptop to recharge them for when I need more juice for my headphones. Very convenient. I've had these for about a year now and they still hold a charge as well as they did when they were new.
