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.

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.

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.

Same price as in any local store. Also, they are only 750mh batteries. The higher the amp rating, the more power the batteries can deliver (last longer). While people are still selling 700mh batteries, 750mh is about the lowest you will find. Better batteries can be found online (850-1000mh) for less.

So far these have been great batteries. We use them in our remotes & 1 or 2 or our sons toys. They've held their charge for several weeks now in the toys & since the remotes don't use much power, I expect longer use for those.

NOTE: You need to use the overnight charger, the NiMH version, not the quick charger. If you use the quick chargers they won't fully recharge. The chargers MUST be for the type of rechargeable battery you have.

A great way to save money in the long run. Great batteries for a good price, fast shipment as well. I'm getting another pack soon as we seem to need a few more...

I got these for my wife who listens to AM radio on her portable Sony radio while commuting on the bus and train, 5 days a week. She would run through a ton of regular alkaline AAA batteries so rechargeables made sense.

She has a pair of the Energizer's and a pair of Duracell's that are of the same capacity and she says that the Energizer's are terrible and hardly hold a charge. We use a MAHA MH-C401FS charger which charges each battery independently so they don't get overcharged. What else can you say about rechargeables? Either they last long or they don't. These Energizer's DO NOT. We recently got a pair of Sony AAA's and they seem to be even better than the Duracell's.

These batteries do not hold a charge much over a 1/2 hour if your lucky, I can't even get them to hold a charge now at all. Save your money avoid Energizer Rechargeable Batteries they don't have a good hold life at all and their life expectancy is extremely short!!!!!

I don't know if it is the charger or the batteries but i haven't had the best of luck with these. I use them in my flashlight at work and i don't more than a week of use. \

These batteries last a long time. Cheaper batteries won't hold a charge after repeated use/charging. I have AA Energizer batteries and after a year they still hold a charge with out any problems.

Of all the rechargeable batteries I have used, and I have used many brands, these are the worst. They are readily available, but they are not worth the money. They will not hold a charge. They will let you down every time. If you buy these, also buy another brand to compare results. Run them in simultaneous applications. Then throw these away.
