First time I took off the battery cover to troubleshoot something there where so many screws long ones short ones common head and Phillip's head. I wasn't going to go thru putting all those back in. Went into the garage and I had a box of 2 inch metal binder clips they are pretty strong not everyone knows what they are, so I put 4 on each long side and 2 on each short side. Works like a charm and holds the cover on nicely can have the cover off in 20 seconds.
