I received a multiplex 3030 for a very good price and before upgrading it to 2.4 Ghz , would like to replace the on board bias battery.
I believe the new battery needs to be installed in parallel before removing the existing one, to avoid a break in supply to the computer chip.
the existing battery is a MnO2- lithium - Sanyo CR2500(? number obscured) which has a bracket spot welded to the positive face, and with the connection to the -ve side of the case obscured.
I have read that soldering to these batteries is not good practice and I'm curious about the negative contact.
Has anyone here had any experience doing this?
Thanks
John

Not difficult to solder a couple of wires to the tracks and add an external battery and case such as a CR2032.
Tape up so nothing comes in contact with it and shove away in a corner somewhere.
Done it on the JR388 no worries.
Then cut the old battery out afterwards.

Thank you Kalle and Bluejets - that is exactly what I need Kalle.
That is also a possibility Bluejets.

This MPX 3030 is too good to throw away and as a MPX user for 30yrs - I couldn't do that anyway.
Cheers
John
