The camouflage-patterned unit has a slight LCD leak, but there are no issues with its operation, and I believe the battery is fine! Basically, all of them have batteries included, but the white one at the bottom in the photo cannot be charged. However, it worked fine when I put in a different battery! The white one at the top didn't work even after replacing the battery. You will need to buy a new battery to use the white one at the bottom, and the charger has poor contact. This is a used item, so returns and refunds are not possible. Thank you for your understanding.
