Game Cart Won't Save? Replace Sega Megadrive Genesis cartridge battery easy 2020

About this video

Shining Force on a Mega Drive cartridge no longer keeps saves, so the maker opens it, desolders the dead battery, fits a new one and checks the joints with a multimeter.

Good to know: Use a cell with solder tabs already fitted and solder only the tabs, never put an iron on the cell itself, and never short or charge it. Soldering means burns and fumes. Old solder contains lead.

Why watch it

Mistakes made along the way are included, by the maker's account, which helps if a first fit goes wrong. The symptom is a game that seems to save but forgets everything after power off.
