Digital Cameras Photo Reviews of Energizer NH15BP-4 Rechargeable Nickel Metal Hydride AA Battery 4 Pack
Customer Review: Okay in some devices...
Summary: 2 Stars
The AAAs I have in my remote controls seem to last a very long time on one or two charges; of course the draw is minimal. In contrast, I have had many problems with AAs used in digital cameras. While some of these batteries keep the Energizer Bunny going and going, for no discernible reason many of them start showing as "bad" in the charger (blinking red light) after only a few charges, meaning... pregnant pause... the rabbit died. Customer Review: replacements
Summary: 5 Stars
I had a set of these with the charger and after 8 years I thought I'd get some more. The energizers work wonderfully and I'm glad they were available for the charger I already owned.Customer Review: Lasts a day at best
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.
Customer Review: very good deal
Summary: 5 Stars
Although people said ,in the battery feild, Sanyo is better than others, I think Energizer is also a good one. I put the battery in my flashlight in bathroom. Because I want to save the utility fee, I did not turn on the light when being in bathroom for a short time, like pee, wash hands and face, except taking a shower. Once charging the batteries, it takes for 2.5-3 weeks at least; everyday I use the flashlight, totally, for around 1 hour. Therefore I think it is a good deal. Customer Review: Awful, don't waste your money
Summary: 1 Stars
I got several packs of these batteries in different sizes, and a charger recently and have just thrown them all out. They are utterly worthless; they don't hold a charge. And stores don't take returns on batteries.
