Replacing internal batteries?

Hello, PVB!

Recently I felt like playing Virtual Boy Wario Land, so I popped it in my VB and found that all my save files were gone. I started a new file, and sure enough, when I turned the system off and back on it had disappeared.

This looks like a classic case of a dead internal battery. I've successfully replaced the batteries in a few Game Boy games before, but I've never tried fixing a VB game. Is the procedure any different? What kind of battery is best? Is there anything specific I should know before I do this?

Thanks in advance!

It is indeed the same process as replacing a GB, SNES or any other cartridge save battery.
I do not know the exact number of the battery, but it is a different one than the GB. Just unscrew your cartridge and you'll know ;)

This has come up a few times in the past. The process is straightforward enough. To quote... me...

I put a new one in my Wario Land a few years back. I de-soldered the tabs (with battery attached), then used a blade to get the old battery free. Then I soldered the tabs back in place.

Next I slotted the new battery between the tabs and closed everything back up - I didn't bother using anything else to secure the battery as it seemed to stay put just fine. And It still works, so yay me.


I hear some places sell batteries with the tabs attached, but it wasn't too difficult freeing the dead one and simply reusing them.

I wonder if you could use an LIR1616 and find a 5V charging circuit small enough to fit inside the cart...

Just pick up a tabbed CR1616 (or 2025 if it will fit) on eBay, remove the old battery and solder the new one in. It's very easy to do.

A rechargeable battery isn't a good option, unless you happen to leave your Virtual Boy running for several hours every day.

I beg to differ. Since the current draw is small, and it goes to zero while you're using the VB, I think a rechargeable would work nicely. It's good that (AFAIK) only a Li-ion cell would physically fit, though; the "memory effect" of other chemistries (I'm lookin' at you, NiCd! ) would ruin it after a few low-drain/top-up cycles.

Now that I think of it, though, maybe a supercap would be even better... But then you would probably have to run each cart for a few seconds every so often. Either that or find some pins that would fit, and make a rack that you can plug all your games into that supplies them with +5V

There is a lot of room inside the cartridge for bigger size coin battery (2020-2025-2032)

Or you could just install a CR2025 (or 2032) and not have to worry about it for 20+ years.

Hey again! It took me awhile to get at this, but I just installed a CR2025 and now it's saving again. Thanks!

Unfortunately, I don't think I have the skills or resources to install a rechargeable battery (at least, not without a step-by-step guide), but if someone else wants to try it I think it would make for an interesting read. ;)

Does anyone know if it would be possible to socket a cartridge for easier future battery replacements?

I did one for a Super Nintendo game some time ago with this video as a guide: link!. Probably not worthwhile since it'll be 10+ years before it has to be changed again, but hey, why not! :)
