Sanyo Eneloop Rechargeable
Best rechargeable batteries
Experts and users alike rave about Sanyo's Eneloop rechargeable batteries. They come pre-charged and ready to use and lose their charge extremely slowly, so they're still 75 percent charged after three years in storage. Furthermore, Eneloops can be recharged up to 1,500 times, so they're much more cost-effective than disposables.
