CH4-57AU 4 SLOTS PORTS kenlti AA AAA charger with 4 x 1.5V 3000mWh lithium li-polymer li-ion AA rechargeable batter for LED falshlight Digital camera Microphone

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

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.

Great product, paid for extra fast shipping but it took a little longer than expected. Other than that it is good.

Bought the batteries for my ATN XSight Scope. They work great, I was having issues with one of the batteries losing charge. The company has great customer service and quickly replaced the battery. Do to the design they maintain full 1.5 v pretty much to they are dead so the battery level indicator really don’t help but once you determine how long they last for the application you are using it for they are great.

Awesome batteries

It was hard to find this type/size recharge battery that had a HIGH power capacity, these do & run my day/night scope well.

Excellent. I bought these because my ATN night vision thermal scope likes to see 1.5 volts. NiCad batteries drop voltage as they discharge. These Kentis work much better.

I bought these batteries to go in a$6,000 thermal scope,i bought 2 complete sets,1 battery in 1 set is larger diameter and it has to be forced in and removed with pliers,i tried to place it in another slot with same results,maybe a flashlight,but not in my scope.Amazon has offered to return and refund-great-as i am not super computer litterate or access to a printer i guess i will eat this order,as a note the batteries do work---but i will not force them in or out---on amazon,s call to chat,my phone never rang but there is a voice mail,beware
