GE/Sanyo Eneloop AAA NiMH Pre-charged 800 mAh Rechargeable Batteries (4-Pack) $12.99
Eneloop batteries offer a number of advantages over traditional alkaline batteries, including up to four times more power when used in a digital camera, high performance even at low temperatures (down to 23 degrees F) during your winter vacation, and a vast cost savings in the long run. The eneloop advantages are even more glaring when compared to typical NiMH batteries: not only are they ready for use right out of the box, but they generally last longer than most NiMH batteries (continuous and frequent recharging can destroy other NiMH models) and save both time and money (traditional NiMH charging is slow when you're in a hurry, while rapid chargers are expensive). All told, you can recharge eneloop batteries up to 1,000 times without experiencing a memory effect; just charge the amount you need and you're set.
This four-pack of 800 mAh AAA batteries is ideal for everything from electric shavers to TV remotes to portable flashlights
