Streamlight CR2 Lithium Batteries 2 pack

I keep a couple of these in my EDC bag for a backup light, and the 3-volt output gives consistent brightness until they die. The two-pack is exactly what I need for replacing batteries in my small flashlight.

The packaging on these is nice and sturdy, so I don't have to worry about the cells rattling around loose in my bag. Used one in a small flashlight last night and it powered it for a solid three hours with no dimming.

These CR2s are holding their charge well in my spare flashlight, and I like that the two-pack gives me a backup ready to go. The packaging is a bit stiff to open, but that's a minor gripe for the convenience.
