Only the one that actually says keeppower is a keeppower branded battery (panasonic 3400mAh with quality seiko protection). Who knows what the other one is. I would buy some 18650 heat shrink then open the wrapper to check what cell it is. It could be a good cell or it could be fake / old rewapped junk.
Heat shrink is easy to use. You can shrink it with a hair drier, over a toaster, over a lighter, etc. Rewrapping a battery , Shrink wrapping batteries
