### ⭐⭐⭐⭐⭐ These batteries are the real deal!
*by L***H on April 22, 2024*

I have used these for years , initially in my NV due to them needing 1.5v (regular rechargables are 1.2 and won't work correctly) and it eats through batteries. Single use alkaline/lithium batteries ain't cheap these days. I was needing a battery for my frother and didn't have any alkaline (what I normally use) so I used one of those. The difference was amazing, the frother worked better, didn't bog as easy and these batteries last several week's of use. There are two downsides though (aside from initial cost): you have to use their proprietary charger and they batteries are 1.5v or 0.0v, all or nothing, no in between there is no fade (Likely due to internal protection circuitry) like most conventional batteries.The up side is that you get good operation through out the charge, the bad news is that you don't get a warning so keep in mind and/or extras

### ⭐⭐⭐⭐⭐ good
*by F***Z on September 4, 2019*

solid batteries, almost as good as the one time use lithiums with just slightly less life per charge, really like these. best rechargeable batteries ive ever had, and i used to hate rechargeable batteries because they'd never last long enough. i use them in pro camera flashes, i can over heat them when im shooting, but its an extreme use case

### ⭐⭐⭐⭐ I like them
*by B***B on December 13, 2024*

Bought these to use in blink cameras because energizer lithiums are spendy$$. The cameras work well with these batteries. They dont last quite as long as the energizer, but these are rechargeable.Only down side in my opinion is the mah rating is a complete lie. But i expect that from amazon batteries.I would buy again and i would recommend them.
