4.0 out of 5 stars Charge them right and they'll last!, September 29, 2009

First off, I would like to say that these batteries can NOT be used in the 15-minute chargers. You'll have to use the 8.5-9 hour chargers in order to charge them up to full capacity. I did some testing with my own charger and the 15 minute speed charger. The batteries worked great with the 9 hour charger, but very poorly with the 15 minute charger.

Additionally, the voltage for these are 1.2v. Note that most non rechargeable AAA's are 1.5V, so you will be getting a lower voltage input. This is especially important for those who are using them for flashlights (reduced brightness) and those who are looking for a good 12V equivalent input for DIY projects (8x1.5=12V as opposed to 10*1.2v=12V, you would need 10 batteries as opposed to 8 in order to achieve a 12V input, for example)

Regardless, these batteries, when treated right and if you know what they're best for are a very good deal.

5.0 out of 5 stars Rechargeable and always ready, October 5, 2007

It is very convenient to have spare rechargeable battereies on hand. This way you always have fresh batteries for your electronics. I am currently in Iraq and I use these batteries for my headlamp and Bose noise cancelling headphones. These batteries seem to hold a charge longer that traditional batteries and it is very convenient to know that you always have a fresh set of batteries available. It is the worst thing for your batteries to die and not have a spare. I switched to rechargables about a year ago and will never go back.

1.0 out of 5 stars Can't hold a charge!!! Worst rechargeable batteries ever!!, March 12, 2009

I bought these batteries for my Sony voice recorder which I use 3-5 days in the week for 4 hour lectures. I used to go through regular batteries weekly and I finally decided that it'd be better to just get rechargeable batteries so I wouldn't have to buy new ones and throw them out a week later.

After fully charging these batteries for 2 hours (I have the energizer compact charger for AA and AAA), I took them to my 4 hour lecture and by the end of it, the battery charge was low. I thought I still had more time, so I brought them to my next lecture. Bad idea! The batteries died 30 minutes later and I missed out on 20 minutes of my lecture because I didn't realize that my recorder had turned off.

Each subsequent use of these batteries just got worse and worse. I was charging these batteries everyday and hoping that they wouldn't die before the lecture was over.

These batteries don't last long at all. I'd say they only last for a few hours. I tried using these batteries for 2 weeks, then I finally went and bought the Duracell rechargeable pre-charged batteries as others had suggested. I've been using the Duracell ones for a week of 4 hours lectures, and I still haven't had to recharge them.
