more mAh from the eveready, i'm going that direction.

I bought a couple of these to use with my Sony BCG-34HD4 charger. These batteries are working great. They're 800mAh (Capacity), larger than the standard AAA size (The also last about twice as long as normal Alkaline batteries). I've used a pair for atleast 50 charges and they're still going. Rechargeable batteries are a much more economical choice for anyone, I use these in an MP3 player. You're pretty safe going with Sony (You can get cheaper NiMH batteries from other brands but you risk getting cheap'os that can leak in your equipment). Remember though, these will only work with NiMH chargers! You should also get a charger that cuts power when fully charged to preserve your battery life.
