So I tried that batteries because 3000mAh sound a lot for batteries. Nearly the same capacity as a smartphone. So I gave it a try!
I use the batteries now in some products like a torch and Bluetooth speakers. The batteries still work Properly. Even after 10 hours of use of the speakers!
I have no measurement system for batteries but they still work.
The package of the battery was also nice. They come with 2 small boxes which can be used for storage of your batteries!
Perfekt Product - does what it should!!!
