Battery

One of the first things you should do after receiving a MVS motherboard is check for battery leakage and replace the stock battery with something more usable. The type of battery used is getting harder to find in comparison to the alternative.

Luckily most of these boards can easily take a coin cell battery holder and use cr2032's to hold high scores.

After removing the stock battery, which is just a simple 2 point de-soldering job. You will want to remove the resistor which closes the charging circuit, as cr-2032's are not rechargeable. Near the location of the old battery, and your new coin cell holder, there will be a 470 ohm resistor (needs verification, don't remember if its 470ohm or 1k), this should be removed.

I would recommend soldering in the coin holder so that the new battery is on the bottom of the motherboard, this makes it easy to replace. On some 1 slots and all 2-6 slots you would need to remove the case and secondary board if you do it the other way.

Once the new battery is in place you should be able to boot the system, rack up a high score, and have it save through a power off.
