Does your Sega CD Back-Up RAM Cart no longer save correctly? If so what you need is a replacement memory battery.

Details

• Brand new CR2450 coin cell battery; identical to the one used by the Sega CD Back-Up RAM Cart.
• A 47uf 16V capacitor is also included. If the capacitor is faulty the cartridge will not operate correctly. Replacing it at the same time as the memory battery is a great idea and we include one for free.
• Installation does requiring soldering, although step-by-step color instructions are included.
