AA Rechargeable Batteries 1.2V 2500mAh High Performance Pre-Charged AA Batteries - 4 Pack

They’re okay. I will say that the battery size diameter is different from normal batteries so they may get stuck in some devices. I will the charge on the batteries last forever. Not tomention how fast they charge. They work very well and are the best value for your money as long as they fit.

These rechargeable Nickel Metal Hydride batteries arrived fully charged and in excellent condition. Note that NiMH batteries produce only 1.2v instead of the 1.5v you might be accustomed to seeing, but in most applications this won't matter and won't even be noticeable. If you see a difference in performance, you might need to use conventional Alkaline or carbon batteries in that device.These batteries have a 2500 mAh capacity, which translates to long life. Alkaline AA batteries, by comparison, range from as low as 1750 to 2800 mAh in the premium ones, so these batteries are in the top part of the range.They recharged nicely to 1.3v after their initial as-delivered charge of 1.3v, so they are performing as advertised. I also like that they come in a nice little plastic snap-case for storage and transport.Rechargeable batteries are one small way to avoid putting toxic metals into our landfills and polluting waterways and oceans. Even if you're not an environmental warrior, you can benefit by not having to buy batteries every time one stops working. And if you're like me, you have lots of battery-powered devices that always seem to need fresh batteries!From both the pollution and economic standpoint, rechargeable batteries make good sense, and I'm giving these all 5 stars.

Good product Good Price!!

GREAT

Nice set of batteries with a long lasting charge at a decent price. These are definitely a lot better than disposable batteries. I've used these for quite some time and they still hold a good charge.
