My first purchase for this product, will buy again.
I like these 10440 batteries, already have a charger that will charge them. It charges them to full rated capacity. I like the build quality. Since this is my first purchase I can't speak to longevity time will tell.

Good value for 10440 Lithium cells
I haven't tested them for capacity yet but I did notice a big difference in a single cell flashlight rated for alkaline, NIMH and lithium 10440 cells. Very happy with their performance and price.

Use for my loops
These are hit or miss. Some work with my dental loops and some don’t. They are so cheap in comparison to the brand name so if I can get 2 out of the four to work I’m happy. I change them out every 6 months or so. They do not take long to charge and I switch mine out after every patient. They last about an hour and 20 minutes.

Great with the Snowsky Retro Nano
Bought these for a Fiio Snowsky Retro Nano Bluetooth DAC/Amp. I like these batteries allow me to reload the nano and remove the need to charge to get more use out of it. 10/10 would recommend to anyone who owns a retro nano or plans on getting one. Each battery lasts about 5-6 hours for me with LDAC.

Used for a while with no problem
So far,so good. Using them in a stream light, micro flashlight really kicks up the lumes! Been using them for an increase in light intensity. Big boost over 1.5v aaa battery
