Re: Replace the Battery in your Game Cartridge! **56k warning**
If you can find a battery that has tabs it will save you a lot of trouble in attatching your own. You can buy them online (part number P223-ND at
digikey.com) if you want to pay a lot for shipping.
You can also find battery holder clips that you can solder to the cartridge and then just put the battery in it. These clips are the kind of thing you may see holding the CMOS battery on a computer motherboard. You would just have to make sure it is thin enough to fit in the cartridge.
If you don't want to spend a load of extra money buying batteries with tabs, you can build an spot welding device. This will work much better in attaching tabs to your new battery than trying to solder it.
If you have a disposable camera (or any kind with a flash that you won't mind taking apart), you can open it up and make your own welder.
- Find the capacitor inside that stores the charge to power the flash.
- Attach a wire to each lead of the capacitor.
- Use an insulated tool such as pliers to hold the tab in place. If it isn't held down, the spark may make it fly off the battery.
- Once the capacitor is charged up, place one wire touching the edge where the tab meets the top of the battery.
- Touch the second wire to another point where the tab touches the battery.
- Remove both wires.
When the second wire makes contact, a spark jumps between both wires, melting the spots where each wire touched the metal. This allows you to fuse the tab to the battery. If you practice this, you can get it to work. Sometimes you get a stronger hold than others, so make sure you fuse multiple areas where the tab touches the battery.
I covered the tabs with epoxy to add extra strength.
Now your battery should be ready to solder back onto the circuit board.
Update:
I have finished soldering the battery, with its finished tabs, back onto the circuit board. I have tested that it successfully supplies 3 volts, and I have played it for a while to verify that the saves are sustained.
The most important thing to remember when replacing your battery:
Make sure that there is a firm connection between the battery and the board at all times.
