So a guy on youtube that goes by the screen name of "TheDamoMonster" posted a video that has an excellent solution to the problematic NeoGeo MVS rechargeable battery:

He preformed this mod on a MV-1F PCB which just so happens to be the same board I have. I just completed the mod myself following the steps in his video to a tee and it works FLAWLESSLY! I was so excited, I thought I would share the information here.

I wonder how long the coin battery will last. Just doesnt seem that much better than a remote mounted cordless phone battery to me.
 
Piece o'Cake.

There are instructions out on forum member Xian Xi's web site and out on my repair logs.

I did the mod to my 2 slot board in the cab in my game room just over the weekend.

I never thought of doing it that way. Its been my experience that rechargeable batteries get a memory over time where if they are used again and again without fully being depleted, they hold less and less of a charge each time. (Think Dreamcast) This is why I did not want to replace the battery with another one of its type.

I bet the coin cell will probably last 5 to 10 years, most boards that use SRAM that I have dealt with generally do. I could always preemptively replace the battery with the board turned on in a few years and the memory should remain in tact. CR2032 is a fairly inexpensive battery.

I had no idea this was so widespread, but I figured someone here could gain use of the tutorial.

I have a board that has had the mod for about 2 years now and my data is still there and battery is still at 3.07v.
 
Thanks a lot for these tutorials, they'll definitely be useful :)
I removed a bunch of leaking batteries from faulty MVS slots at home, but I didn't get around replacing them yet ...

Battery holders can be found in any decent electronics shops (like here for those like me far from the USA ;) )
 
15 minute video for that?? Couple of pics as on XX's site would have been more than sufficient.

I am new to NeoGeo as of about a month ago and was unaware of XX's site so I found it very useful. Now that I see his site though, it's pretty awesome. :)

Your welcome, and thanks for the source on battery holders. I was eager to replace mine and had a good trash motherboard to harvest it from but it would be a good idea for me to stock up for future projects.
 
I do the mods on NG boards sent to me for repair, but out of respect for XX, I don't sell them on my site.

It adds another $3 to the repair.

I did my 2 slot a few months back. SNK seems to have designed the board (at least the 2 slot) with this possibility in mind, as there were appropriate pads and through-holes present on the board. Anyone know why they left space for so many possibilities? Were they just preparing to cheap out if rechargables got expensive or something?
 
I'm guessing when they designed the PCB they used a generic battery holder as a place holder for the battery since there probably wasn't a model in their system for the battery they used.
 
Its so they can use different types of batteries in case they couldn't get any of a certain type/part.
