Battery

Big difference between my old 2600mah battery and this one. So far, I’ve no complaints. My small nitecore flashlight has five settings; I use it on the second setting for both the 2600mah and 4000mah.
I notice that it takes a lot longer to fully charge.

The protection circuit on these batteries prevent me from closing the battery door. Just a tiny bit too long dimensions.
Basically cannot use them. I really wanted to use :(

Powerful battery

Last all day in a 1000 lumen headlamp at max brightness. Unsure on my 2000 lumen as it has extra charging battery. Am pleased with everything except the price.
