The stock coin cell battery that powers the cmos on my motherboard has japanese words, but it says CR2032 3V. If I put a Energizer or Panasonic battery of the exact type in there for example, will it work fine?

You're in luck. Any make (panasonic, energizer etc) will work just fine. If your battery isn't already completely dead, remember to save your bios settings before removing the battery, or your setting will revert to default. If your battery is already dead, then no need to save your bios settings.

Thanks for the info

Yes any brand will work as long as it has the same model type number, you can easily get a new battery at radioshack thats where I get mine and they almost always have them in stock but sometimes some types they dont but thats rare

yes, any kind that has the same specs will work.
