Get 12 pre-charged rechargeable AAA batteries for $17.99
Or a dozen AAs for $21.99. Either way, it's not much more than you'd pay for the typical 4-pack. Just make sure to get a charger so you can juice 'em up again.
I'm a big, big fan of rechargeable batteries. But it seems I never have enough to go around, what with all the Xbox and Wii controllers, kids' toys, flashlights, and other battery-powered gadgetry around here.
Today only, Pennywise.biz has 12 Duracell pre-charged rechargeable AAA NiMH batteries for $17.99 (plus a penny for shipping). To put that in perspective, my local Walgreens sells a four-pack for $15.99.
Need bigger ones? Shnoop (Shnoop?) has 12 Duracell pre-charged rechargeable AA NiMH batteries for $21.99 shipped--also today only.
Because these are pre-charged, they're ready for service right out of the package--highly preferable to the rechargeables that have to be, well, charged before you can use them.
Duracell says these CopperTops will retain their charges for a full year, and that you can recharge them hundreds of times.
Of course, you'll need a charger. Best deal I've found is the Duracell Value Charger for $5.76 (plus $5 for shipping). It comes with two pre-charged AAs (bonus!) and can charge up to four AAs or AAAs at a time.
Rechargeable batteries may have higher upfront costs, but they'll save you a small fortune in the long run. They're way better for the environment, too.
