Blown battery on MVS MV1

[Matan]

Hi all,

need some help with a case of leaked battery and damaged capacitors and oscillator.
I've attached a photo of the area after the removal of the battery.
I understand that I will need a 32.768 kHz oscillator and 0-30pF variable capacitor (missing in the photo).
Can anyone confirm?
I would also like to get some links for the missing components (like from Mouser.com) so I will know I'm buying the right stuff.

Many thanks

you need to remove those parts, and the chip and resistor array - everything green.
then use a fiberglass brush to get down to the copper tracks and smear flux on it and tin it with solder again.
then you can fix any broken tracks while they are easy to see.

only then do you put new parts on the board.
if you leave out the charging resistor that is in parallel to the battery diode you can then fit a cr2032 coincell holder and use disposable lithium batteries.

Also as a first step, clean up any battery residue with white vinegar or lemon juice. Then wipe down 99% iso. If you havent already.

Can you help with obtaining the parts?
Like the variable capacitor, I’m having a bit of trouble finding one that will fit .
