Do you guys replace the internal batteries in Nintendo game boy cartrages? If so, do you sell the batteries? Also, how much do you charge for the work?

Please feel free to bring in your device for a free diagnostic. Typically Gameboys take double AA batteries, but we can take a look at no cost

No I'm talking about the game cartrage. A pokemon game to be specific, It has an internal battery that needs replaced. Its a little cr1616 3v battery inside the game. To replace it requires a special screwdriver to take the game cartrage apart and the old battery needs to be removed with a solder iron and a new battery specifically one with solder tabs can be soldered on. Would you guys be able to do this and how much would this cost? There's a guy on youtube that has instructions and links to the stuff he did it in 5 minutes. I would try but i dont have the equipment. Thanks for your reply
