It seems to me that at least one screw per group has some kind of Loctite on it. Most screws were easy to remove, but there was always one per group that was really hard to remove. It basically would strip out if you weren’t super careful. I also could not pull the battery out by hand. The battery would wiggle back and forth a little, but the wires broke off after a bit. I tried to push the battery out from the other side, but I had no luck. My end caps were on very well and also did not pull off by hand easily. One of them cracked near the screw holes in a couple of spots. I wouldn’t say they are glued down, but I think the rubber seal sticks if it hasn’t ever been removed before.

This is the second time I tried to fix a FLIP speaker with a battery replacement and the second time I failed. Super frustrating since I know this would fix the problem, but JBL makes these speakers in such a way that it is not an easy repair. This comes from a guy who has been an Electronics Repair Tech for over 20 years.

I also found that the handle need to be removed at least part way. Two more screws hold the motor assembly in place and they can’t be seen with the handle in place. The top piece where the filter goes needs to come off. There is a hidden screw under the switch, so move the switch to II to seen the screw cover first. I used a tiny flat head screwdriver to pop the cover off.
