For your guys information, those picture shows the BST 33/37 are really fake ones. Even there is Midland sticker (people can do wonders by using heat blower to easily remove the Midland sticker came from its original place and stick it back to fake batteries)

Original batteries have shinning layer battery cover.

AP set usually provide fakes batteries as those ori batteries being taken out and sold separately. I was lucky enough to purchase a AP set K750i with all original parts identical to was you can get from Midland. How do i know? Well i own a Midland K750i, made a comparison... Is identical and the best part the battery is ori!

Is original battery
