Replacing NES/SNES Batteries With A Socket
BadChad:
Heres a little tutorial for replacing batteries in your NES/SNES carts with a socket for easy battery replacing in the future. I did this tutorial using my double copy of Zelda.
Heres a list of items youll need:
- Game Bit Screwdriver
- CR2030 Battery (I bought 100 for $10 on eBay)
- CR2030 Sockets (These are the ones I bought)
- Soldering Iron W/ 60/40 Tin Lead Solder
- Desoldering Pump
- Small Flathead Scredriver
- Exacto Knife
- Small Cutters and Pliers
Start by cutting out the old battery with cutters and then desolder the pins from the board using the soldering iron and pliers.
Now unfortunetly most of the clips available online dont fit properly onto the board since the pins are a little to far appart or their too big and the cart wont close. Ive asked around online a bit and no one has been able to find an online store that sells clips that fit perfectly. If you have the same clips as me, your in luck.
Start by cutting these little tabs off the bottom and the plastic around the pin with your exacto to make the clip sit flush with the board. The pin will also pop out much easier once the plastic around it has been removed.
As you can see here all the plastic stopping the clip from sitting flush has been removed.
Then you going to take your exacto knife and make a small cut in the plastic right next to the existing hole by pushing down. Stick your small flathead screwdriver in the new hole you just cut and work it around a bit to open up the hole a bit more. As you can see in the picture I know have a new hole a little closer to the middle right next to the existing hole giving me enough room for my pins to line up perfectly.
Pop you pin into the new hole and solder you clip to the board. You may need to trim that pin so its fits in the smaller hole on the board but be careful as I broke a few pins doing this. Or Solder the clip to the board and pop in a fresh battery. Close up your cart and your done. Make youself a save file on your game. Turn it off for a few minutes and try it out again to make sure it worked.
Cool thing is there was an existing file on the cart before I removed the battery, after I finished soldering on the clip with a new battery I tested the cart to find the file was still saved on the cart!!! Im guessing it takes a few minutes for the energy from the battery to completely drain from the cart after its been removed because I have no other ideas as to why els the save wouldnt have erased.
I have yet to try this on an NES cart but it should be the same process and there shouldnt be any problems.

Good, but I find 2032 batteries better. ;)
And I did it with these clips, which you don't have to cut of or anything. ;)

I am using 2032 batteries. Its cool that you know of a site with clips that require no modding. Only thing is your paying more for your supplies. I got 100 batteries for $10 and 150 clips for $30. That means Im good to fix 100 games for just $40. You couldnt even get 100 clips for that price. Looks like your paying much more than you need to. So if you dont mind doing a few simple modifications and have a large ammount of games to replace (as I do) this is a much ceaper solution.
