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.

I bought these batteries a couple of years ago for my bluetooth headphones. They are still going strong despite several thousand charging cycles. These batteries hold their charge pretty well and don't drain as quickly as some lower priced batteries from lesser known brands. They are by Sony, so enough said on quality!

The baby monitor (a "Philips AVENT Digital Screen Baby Monitor with DECT Technology") we purchased a few years ago for our 2-year-old daughter was no longer holding a charge for any decent length of time (30 minutes or so max). After checking the customized batteries in it, we purchased these batteries as a replacement. After about 24 hours of initial charge time, they now will hold a charge for at least 4 hours (we haven't tried any longer) and seem to be working perfectly for normal baby monitor usage.
Please note, however, that Philips had a customized battery container including a small metal strip to join the negative ends of the two batteries. As these Sony batteries are individual, I simply took metal strip off the original Philips battery pack and taped it onto the new Sony batteries in the same manner. I've no clue if this was actually necessary, but it was quite easy to do and certainly it doesn't seem to have caused any issues. Obviously, this isn't Sony's fault so no stars deducted -- but it's something to keep in mind if your considering replacing the batteries in a Philips baby monitor.

I am using these batteries (now they come at 900mAh) for my baby monitor - it takes 3 AAAs.

The monitor is on up to six hours a day and a set of batteries lasts about a week.
People say that in digital cameras Ni-Mh last longer than regular alkalines, but this was not the case for me. A set of Duracell alkalines lasted a little longer than these and a set of ultra batteries lasted about 10 days. I guess that this is because the monitor is a low-drain device and batteries seem to behave differently when used in a low-drain or a high-drain device like flash or digital camera.

Anyway, rechargable are always a better choice, I am starting to save money already.

I use these batteries for the wireless headphone after OEM supplied battery died on my Sennheiser headphone. The first replacement was Sanyo but after about six months with about 50+ charging, the battery life was becoming notably shorter. It is supposed to last about 500 charges so it was either defective or poor battery performance. So I decided to go with a little more name brand and purchased Sony. This probably is manufactured by some other battery maker and labeled as Sony but I really didn't care since my other Sony wireless headphone still has OEM Sony battery and that is over two years old.

It is lasting more than 3-4 days per charge with about 2 hours use per day so I am happy with it.

What can I say about batteries? Either they work or don't. I have been buying rechargeable batteries because they can be reused. These appear to hold their charge well.

I rated them 4 stars because it just seems a bit silly to say I LOVE batteries.

I purchased 3 sets of these to replace the ones in my wireless home phone system. I like the fact that they were of higher mAh than the originals hence longer reserve power.

Sony rechargeable batteries are just fine but I sent these back because the device that they were to used with was also sent back. Otherwise, a good enough product.
