I need to replace the internal lithium battery on a yaesu FT-416 - how do I do this?
I have a Yaesu FT-415 and the same problem. My original battery is a SONY 1220-VJ2H (solder tabs, blue insulation on the outer edge and two stick-on paper insulaters) and is soldered in to the Control PC board (mounted vertically). I'm going to get a new battery and hopefully am brave enough to get the soldering iron to the board. It looks like you have to unsolder the board from the speaker to lift it up enough to get at the solder tabs on the battery, luckily I have access to a Pace soldering station with a vacuum pump. I'll hopefully try this next week and get back to you all.
