Customer Reviews

Awesome batteries! Quick charge!
these are exactly what I was looking for. Came fast, charged up and have not needed a recharge in almost 2 weeks! Im using a Coolpix Nikon Camera!

Pretty God but the 2700mAh would be better
This pack is really good, the price is worthy, they works perfect, I buy this as a bundle pack with the charger, but the charger comes with a 2700mAh, so, If you care a lot duration time, notice, that using this 2500mAh with (example) a 2700mAh would be like using all batteries of 2500mAh.
I bought this because I need for my Lego Mindstorms NXT, since the official Lego battery (and charger) cost much, much more.

Self-discharges at an alarming rate
I bought 4 2300mAh Sony batteries in 2002 when I bought my digital camera. Those worked pretty well but after a year, they started self-discharging at an alarming rate and couldn't keep their charges longer than a few hours.

Since they worked pretty well for me at first, I decided to continue with Sony and I bought some 2500mAh batteries to replace the 2300mAh ones. Bad mistake. The newer batteries were similar to the old ones and self-discharged at crazy rates. Still, I wasn't sure if I had bought some fake Sony batteries as I didn't believe that the quality would be so bad.

So, two years ago, I happened to visit Tokyo and I bought 4 new Sony batteries and a charger there because I had read that batteries in Japan were sure to be the real deal and usually performed better. Same problem. To be fair, I read about the same problem across many different brands so I'm not sure if other brands are any better. But I've been put off from buying any new rechargeable batteries because of these problems. Not only are they expensive but the performance leaves a lot to be desired.
