Sony Rechargeable Ni Mh Batteries By tribefan on - Updated Oct 15, 2011
I really like these Sony rechargeable batteries. I've have lots of success using these in high-power devices, like my digital camera. The kit comes with a charger, which can recharge up to 4 AA batteries at a time, or 2 AAA batteries. It also comes with 4 powerful batteries, type Ni-MH 2500, which should last a while in your PDA or camera. I've found that it takes about 2 hours to charge 2 AA batteries, which isn't too long. If you want to charge the full 4 at a time, though, it could take up to 4 hours. I love the fact that it's a smart charger. It will stop sending power to the batteries when they're full, unlike many other chargers at this price point, which helps the batteries to last longer in the long run. Overall, I completely recommend this charger. Rechargeable batteries will save you money, and for only $20, you can't get a much better deal than this.

I also use these and they seem to last longer compared to other rechargeable batteries that I have used before.
