Matrix 12 battery replacement

 

Hi folks just a quick question, I have a replacement Panasonic br-2/3v battery on its way for my Matrix-12, How easy are these to replace? ive managed to remove the old battery... the legs on the replacement are a fair bit longer so i may have to trim them...no problem there but regarding the legs themselves, do they have to travel through the pcb board for proper connection or can they just be soldered to the terminals on the processor board, the drill holes in the pcb for the battery are really tiny, smaller than usual... and im not sure if the pins would fit through, The older battery was soldered either side of the pcb but not both... ! any thoughts? if its too fiddly i might just get a local tech to have a look, my eyes aren't as good as they used to be.

Thanks again folks

It's not a good idea to make a connection without going through the
board. The solder joint is both an electrical connection and a
mechanical connection. If the joint is too small you put strain on the
small area where you did solder. Especially with a bulky part like a
battery. Worst case the mechanical strain can peel the copper of the
PCB.

Did you unclog the old holes? E.g. with a solder sucker.

Whatever you do, be careful not to damage the board. It's easy to
damage the board while removing components. If you're out of your
depth, go to a tech.

Ah cool! thanks for the advice, was on to a tech here in Ireland but couldn't give an indication as to when he would be free to take a look at it , so took a look myself... and hey ho! worked like a charm, prepped the site,clipped the pins, cable tie'd the battery in place for easier soldering,flux and solder at the ready....job done! put back in the processor board,gave it? test run... all good! loaded a back up of my singles and multis... sounds so alive! hopefully that's it now for another ten years... hahaha p.s. to Jacob - yea solder sucker and braid,site cleaned with isopropyl alcohol,and left to sit.
