How To Change Dead Batteries On GameBoy Cartridges (Without Soldering Iron)

Hello there mates, i know its been a while since my last post, but i was a bit occupied with my uni, so here I am once again to give useful tips and instructions. This time im gonna guide u step by step to learn how to replace ur batteries on ur GameBoy Cartridges. If they work just fine but they cant save ( the saving process completes but then u cant find the save anywhere) then it means that the battery inside responsible for saving is dead and needs replacement. I was browsing around the net for some time to find several ways to do it and i found two different ones. The first one included the use of a soldering iron and the second one just some adhesive tape. So I prefered to go the easy way at first to see if it works in the first place (i change batteries without using soldering iron) and it really does. There is gonna be another post soon that i ll be using a soldering iron, so whoever is interested just stay tuned!!! Well, i wont blubber any longer, here is exactly what i did:

1. What You Will Need

a) A Gameboy cartridge with a dead battery ( I used original Pokemon Gold)

b) An adhesive tape

c) A new battery CR2025 (3V) or a CR2032 (the second one has longer lifespan than the first one as i read on the web but i used the first one)

d) And a pair of tweezers

2. Unscrew The Nintendo Screw On The Back

You cant use a conventional screwdriver because Nintendo's screws are unique so u just have to grip the screw with the tweezers and turn it counterclockwise. This might be a bit tricky because its hard to get a good grip but u should manage it since i did.

3. Slide The Front Part Downwards

In order to open up the unscrewed cartridge, u need to slide a bit downwards the front part to get it apart.

4. The Inside of The Cartridge

Having opened it u should see the inside which consists of a circuit board and the battery on the upper right corner. U can clearly see that the battery is attached with one metal pin on the fron side and one more on the back (well the back side isnt totally visible). So if u dont want to use a soldering iron here is where u have to pay attention and be really precise and gentle with ur doings.

5. Dettach Both Metal Pins Without Damaging them

Here is where u have to be patient and gentle with ur cart. find a spot where the tweezers can fit between the pin and the battery shove it in there and with soft moves try to detach it a bit. If u will be patient it will come off in a while and the pin will be screwed up a bit but in one piece. Do exactly the same thing with the back one and u will have the battery out and ur pins safe...The hard part is done!!!

6. Wear The Yellow Plastic On Your New Battery

Cut the yellow plastic (from the old battery, it can be done even with ur nails) and wear it to ur new battery.

7. Flatten The Screwed Up Metal Pins

This can be done even with ur tweezers and the more flatten they are the better contact will have with the battery.

8. Stick With Tape The Pins To The Battery

Make sure that u place the battery exactly the way the previous was in the cart ( the side with the letters down). Stick a piece tape to the back of the metal pin with the sticky side up and place the battery on it to stick. Press it down. Then do the same with the upper pin and ur gonna have a new "bandaged battery cart". For more stability u can stick this whole battery thing with the green plastic to make sure it stays put.

9. Put The Parts Back Together

Put the circuit board (green plastic) inside the back half of cart then place the front part on top of it and slide it a bit upwards to click

10. Test And Screw It Back

Test ur cart to see if it works. I tested it and it works like its new. It saves just fine and with no problems so it should be the same for u!

*WARNING*
Im not responsible in anyway in case of damaging ur cartridge. i just give some instructions. If u wanna follow them then its up to you!

ENJOY!!! U GOTTA CATCH EM ALL!!!
