Sanyo makes Eneloop batteries that are rechargeable. Each Eneloop battery can be used up to 1,500 times. This will reduce the amount of batteries that end up in landfills. Eneloop batteries also last four times longer than your traditional Alkaline batteries, holding 75 percent of their charge even after sitting in storage for three years. You will need a Sanyo Eneloop charger in order to charge your Eneloop batteries. Warnings Writer Bio
