Replace a dead SNES cart battery

Gutted. Me and my wife had a marathon super Mario world game, switched on the next day and - no save :-( dead cart battery. So I bought a batch of 8 cr2032 battery holders on eBay for £2. Thought if you're going to replace a cart battery, may as well make it easy to change in the future.

First unsolder dead battery :


Use a solder sucker to clean holes out, the battery holder will fit right in!


Make sure to get positive and negative the right way round. Positive is on the right in this photo toward the centre of the cart.

Make sure all joints are good and solid, shove in a battery and enjoy!
