I have the replacement batteries I put on EBAY. $26.50ea FREE SHIPPING. Had to buy a crap load to get in the US. I just changed my battery to find the original bloated! Almost like the plastic around it filled up with gas. Hmmm. These directions for great by the way and as Greg said didn’t need to remove the metal plate. Those magnets were a pain in the a! Suggest holding them down as well as the speaker so they don’t pop out. Works great now! If you need, check my Ebay. Thanks Garrett for taking the time! BTW Did you see they are coming out with a TriCorder. Have to register for it now! https://www.ebay.com/itm/Star-Trek-Bluet...
