How do you replace batteries in game boy / advance / ds cartridges?

Recommended Posts

I believe GBA & DS carts use flash memory.

I think you are right.

 

In the GB/GBC carts, you just need to open up the cart, remove the old battery and attach a new one. Kinda sucks though because the batteries aren't really meant to be replaced, so you have to kind of pry them out of there and then solder a new one in place, which is dangerous because you shouldn't really be holding a soldering iron to a battery.

The GBA is a per-game issue

As I understand things, GBA carts can use static RAM, flash RAM, or EEPROM. SRAM needs a battery, the others don't.

Actually, you gotta desolder the old battery's tabs from the board, then they come right off. You don't need to solder directly to the battery--that's either a spot welder (I've watched this be done) or a "stapler" of sorts that attatches the tabs.

From there, you solder the tabs back to the board (with the new battery attatched to 'em) and you're good to go.

You can order batteries that has solder tabs prefastened on. And it'd be a lot better to get those than to get a plain battery and try to solder tabs on it. Don't solder it long enough, the solder and tab will come off. Do it too long, the battery goes boom.
