These Are Good Low Discharge Batteries 1/12/2020 3:24:56 AM

Pros: These charge well on two different charge systems.
I use mine for metal-detecting, I'm getting longer usage between charges, than I've seen with standard rechargeable batteries.

Cons: haven't seen any CONS yet, I'm still learning the batteries.

Overall Review: I'd definitely tell other users, about this brand of batteries.

Best rechargeable cell I have used 11/25/2018 1:27:17 PM

Pros: They come ready to use, you can let these sit for weeks or even months and they still have charge

Cons: None

Overall Review: I've tried lots of different rechargeable cells over the years...these are the best I've tried. They seem to last forever (lots of charge cycles) and they seem to hold a charge almost like an alkaline. Not much to dislike...

Works great 1/12/2018 10:40:20 AM

Pros: Keeps charge for a long time, great for general use, made from quality materials

Cons: None

Overall Review: You may want to read up on other types of batteries if you are using this for cameras, but this will work great with a camera as well. Also, you will want to pair this with a Maha MH-C9000 charger. That charger is the best rechargeable battery charger period. I would donate all of your other ones once you get the Maha.
