Product Reviews of Energizer Rechargeable AA NiMH Batteries (8 Pack)
Product Review: WASTE of money, buy Eneloop instead
Summary: 1 Stars
I have bought 2-3 packs of these batteries, all disappointments. You'd think such a simple thing was basically failsafe, right? Nope. I thought I had just gotten a bad batch the first time. Nope again. The only way I can use these batteries is if I charge them right before I need them. I can't even tell you how many times I went to go play Wii and then realized ALL of these batteries were dead. Even worse was I had charged them fully no more than 2 days prior. Total garbage in my opinion, my brother even had some which all do the same thing as well. So, unless you are extremely organized and plan out when you want to play video games, use TV remotes, etc... spend your money on anything but these. I had a pair of Fuji rechargables that came with my first digital camera 10 years ago that hold a charge WAY longer than these shiny little turds. The Energizer bunny has sh** itself and died.Product Review: Do their job very well
Summary: 5 Stars
I have a set of these batteries and use them to power my Wii remotes and wireless mouse. It is incredible how long they hold they last before needing to be recharged. The mouse lasts about 3-4 months and the Wii batteries have been through over 16 hours of play time and are still holding a charge. I should also mention that I have had them for almost two years now and they are still performing well. They have been great for me, but others have said that their batteries are not holding their charges very well. It seems like this model is a mixed bag, but I am only rating them based on my experience. Product Review: disappointed

Product Review: Useless if you like batteries that have power in them
Summary: 1 Stars
NiMH rechargeable batteries from two generations ago had capacities around 2000 mAh and they were pretty decent. There was chemistry change around the 2005 timeframe that allowed for higher capacities such as these Energizer 2450 mAh batteries, but that came with a major tradeoff. Yes you can get the higher capacity, but they would discharge at a much much higher rate just sitting there. Charge them and in a few weeks they'd be dead again. The previous generation might have lasted 2 months before going completely dead.
These Energizers are simply the worse of the worst for self-discharging. They weren't so great brand new, and after being in service for a bit mine are down to where they will self-discharge in about a day. No joke. They're useful if and only if you're going to know 8 hours ahead of time when you'll be using them, quickly pop them out and shove them into your device, and then use that device in such a way that they'll be drained within a couple hours.
Instead, there's is a new generation of NiMH batteries called Low Self-Discharge. They have sneaky packaging like Duracell Precharged. They also show a lower NiMH rating on the package, so you might look at them and laugh as I did the first time I saw one in the store. "Precharged? Who cares? Look, it has 80% of the capacity of these Energizers..." Well, don't believe the lack of hype. They've managed to solve the number one issue with rechargeable batteries, yet don't communicate fact that effectively enough on the packaging.
Instead, these new LSD batteries hold the charge almost as well as alkaline batteries. This unstated fact entirely changes how you can use rechargeables. It used to be that you would change the batteries immediately before using them. Now, you simply use them in your device. When you pull them, charge them back up and then toss them in the drawer to be used again next time. If you have kids with toys, then you know how how important it is to have batteries at the ready, and the new LSD batteries actually fit the bill. If you use these in a digital camera or flash, charge them and leave them in the camera. They'll be ready to go when you're ready to use the device.
In short order... avoid these Energizers and buy one of the following instead....
Duracell Precharged
Kodak Precharged
Rayovac Hybrid
Sanyo Eneloop
Rigorous testing by verified nerds shows that they each perform within a few percentage points of each other, so just get whatever is on sale. The Kodaks and especially Duracells can be found in local stores.

... and they come out of the charger dead.
I bought these and a charger because they were advertised specifically for use in cameras. I expected them to wear out eventually, but certainly not this quickly! Would not recommend, especially for a camera.
