Digital camera reviews of Energizer Rechargeable AAA Batteries (4-pk.)
Digital camera Review: After a month they don't even last THREE HOURS! AWFUL!
Summary: 1 Stars
I use mine in an LED booklight for my Kindle (AAA) and in the Wii Mote for the kids (AA). I've only used the AAA about 5 times and each time they hold the charge less and less. Last night I put 3 freshly charged AAA in my Belkin Clip-On Reading Light for Kindle (White) [Amazon Frustration-Free Packaging] and it didn't even go THREE HOURS until it dimmed to where I couldn't see. Unbelievable.
I can get cheap AAA batteries at the dollar store - and they at least LAST. I've had better luck with the Energizer rechargable AA batteries lasting a bit longer and holding a charge a bit more but these AAA ones are just the ultimate in craptastic.
Save your money. Chose a different brand!
Digital camera Review: Better to pay for the name brand this time
Summary: 5 Stars
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.
Digital camera Review: Can be found anywhere for the same price
Summary: 2 Stars
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.Digital camera Review: Can't hold a charge!!! Worst rechargeable batteries ever!!
Summary: 1 Stars
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.
Digital camera Review: Charge them right and they'll last!
Summary: 4 Stars
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.
