I replaced one a while ago. The battery costs like 2$ at radio shack. The problem is that it has two tabs stamped on the battery case to put it on the curcuit.

What I did was de-sotter the old lithium battery . I sottered two wires to the battery and sealed it with electrical tape. I sottered the wires to the board and put the battery in a good place. Sure it doesn't look professional on the inside, but it worked for me.


I sent that transmitter into JR and told me that they replaced the lithium battery, but they replaced it with a bad one. That person messed my transmitter up somewhat. Every other time I sent stuff in they did a really good job.
