Has anyone here ever changed the internal battery on a KLX 135A Looked inside mine today but did not see where it's located. Fairly sure mine needs replaced.
Thanks.
Yes, I had to change mine. Actually, I had it done at a local avionics shop. I could not find the battery and finally after talking to folks at shops, I decided to let them do it. Glad I did. Apparently its not real easy and is soemwhat hard to get to. Its a soldered in type battery, not something that just plugs in. I think the battery itself was a little over $50.00.
