Try checking if it charges when the battery door is open slightly. Hold the door shut with barely any pressure used a rubber bracelet like anti drug businesses and other places give out and it worked perfect lol maybe use a old school I <3 B××bies bracelet for some style all jokes aside i think the metal hinge inside needs tweaked a bit that or the metal connections on each end the battery need tweaked for less pressure so the batteries arent pushing against the got dang doorflap... P.s when u close the doorflap slide the sliding lock/release all the way locked so that doesnt start to happen in the first place
