The RIGHT Way to Replace Gameboy Cart Batteries

[@KyleAwsm]

Hey all, check out my updated version of this tutorial here: kzbin.info/www/bejne/hKqoiYWOmtp0a9k After reviewing my old video and giving it some thought, I've decided to redo it and give some better instruction, as well as correct my mistakes from THIS video. Cheers, and thanks for watching! 🙂

Hey I wanna ask you some thing , so recently l gave my gb games to a technician, they fixed the battery’s of the game but it was the wrong battery he replaced a Different one (CR 2032 ) so it is not saving , now should I give it to him and tell him to put the right battery again or will that harm my gb game

I recommend introducing fresh solder to the original solder beforehand, it's going to help with making it liquid way quicker cause You also introduce flux with the solder :) Also with a wick I always clean off the old solder.The problem with heating the solder for so long as You do is burning up all the flux which makes the solder less liquid. So I recommend having some extra flux at hand or a wick can also help in removing excess solder. Also tinning the tip of Your soldering iron helps for a cleaner result in general, but also using some alcohol to clean the tabs afterwards ensures You are left with nice clean pcb and joints. Thank You for making this video. Those solder less videos are really hard to watch!

[@KyleAwsm]

[@chuckstieg]

Yeah I Agree, It's really PAINFUL to watch videos that explain how to fix something without having to use a fucking solder gun. I can't stand NON-solder people and there need to just fix a ridiculously simple solution with a single piece of tape. And can you believe, that it works too? HOW INFURIATING.

[@scramblesthedeathdealer]

@@chuckstieg It works, til they drop their game on the sidewalk and something gets knocked loose inside the cartridge.

[@chuckstieg]

@@scramblesthedeathdealer WRONG, with proper application of tape that shit closes up pretty tight. Nothing is moving around at all, no matter what happens to it. It's going to literally shatter from being dropped before the tape & battery position are compromised. Some people just get such a fucking hard-on from soldering anything they can't handle a more efficient and easier solution existing than soldering. I bet you solder your kid's report cards to your refrigerator too huh? magnets are so impractical.

[@benjaminwade2804]

[@nonchip]

8:45 and that's why you use flux :P also using a hotter iron and/or removing the old (probably lead free) solder should prevent the tip dragging through molasses and let you actually melt the stuff. both your pads/traces and battery will thank you for being roasted slightly hotter for a way shorter time than trying to melt it halfway for ages.

[@emmettturner9452]

Game Boy games were never lead free. Nintendo didn’t go RoHS-compliant until the Wii.

[@emmettturner9452]

The factory flux is spent or cleaned off and the solder is also oxidized. Addinf fresh solder/flux will renew the factory solder but then you may have a bit too much. Any contaminates will float to the surface and typically comes off with your soldering iron tip after reflowing with flux and a clean tip.

[@ixamraxi]

"The best way I've found to replace Gameboy Cart Batteries" would be a better title, as the soldering technique leaves a bit to be desired. No flux, pads not cleaned/wicked, tinning the new battery unnecessarily, soldering temp too low, too much solder, holding the iron on the joint too long, etc etc. Not insulting you, just pointing out some areas to work on and improve for future efforts.. Also, if the battery is not entirely dead and there are some save games still on the game, solder/clip in a battery in parallel to keep the save games until the old battery is replaced, then remove temp battery. A battery in parallel is safe and should not damage anything, as the voltage remains the same.

[@danman132x]

Probably the best tutorial for game boy games here in KZbin, although for soldering skills I suggest you look elsewhere.

[@joeblusnavage5403]

I agree with some of the other comments. You use wayyy too much solder here, If I used that much I would wick it back up before soldering the new battery back in place. I appreciate your efforts of trying to teach proper handling of electronics, however, gameboy carts are really resilient. They're a great way to learn, and if you want to do the job with no tools/minimal effort, thats on you. I've "tape repaired" numerous batteries before I felt comfortable soldering them in place. To be honest, I usually just use a hot iron, heat the solder and pop the tabs off, and just use the existing solder. As long as your tip is tinned and your iron is hot it should be almost effortless. Just seems like an unnecessarily long video to cover something that could be covered in a few minutes. As others have mentioned if you really wanted to show the "BEST WAY" that would be temporarily affixing another battery to preserve saves which may be in place already. Still, its good to show better practices for those who want to learn them instead of brute forcing the old tabs off and just taping back into place.

I've been able to fit 2025s in all carts, just need to trim the leads a bit. I'm guilty of popping the top tab off the old battery with a screwdriver before desoldering. Gives me more control and I don't need to use tweezers. At this point I always replace the battery unless it's obviously been done recently and correctly. Great video.

[@KyleAwsm]

[@questionmark576]

@@KyleAwsm I still desolder the old and solder the new one in, I just pop the tab off first. The welds are usually fairly weak. It's a lot easier to pull it off the board when the other side isn't holding it down.

[@KyleAwsm]

questionmark576 I should have phrased my initial reply comment differently. I know what you meant. :) If I came off as snarky, I wasn't trying to! I'm just exhausted, lolz.

[@emmettturner9452]

A couple tips: Nintendo’s PCBs are typically pretty robust but rotating the battery off of the pad that’s not fully melted like we see here on Link’s Awakening can tear pads off weaker PCBs. It’s best practice to just hold in place and nudge it every now and then until it releases completely. On that note, you almost seem to be painting heat into the solder joints on a few of these. While it may feel like this is heating more evenly and spreading it around, heat conducts through the solder and metal well enough that you’d be better served by just flattening the iron for contacting the maximum surface area and then adding solder to bridge to places that aren’t readily melting. I use ceramic-tile drink coasters as a work surface since I don’t want to melt my ESD mat or heat it inside a plastic shell. Just a suggestion. :)

[@BlazingKhioneus]

Most videos mention that you should use a soldering iron, but many people do not have a solder or the necessary skills to operate it like this. That is the reason why there are many videos of using screwdrivers to pry off the weld points from the battery. It simply isn't feasible for some people. Especially a little kid trying to revive "his dad's old game" and things like that.

[@str33tlevel]

i mean...i tend to see lots of tutorials on replacing the battery...and good job on this tutorial as well...but it does not solve the main issue that people have...which is making your old save data work again...and there is actually no method to recover your old save data...for example if i complete a game and the battery dies, you can do this tutorial, replace it and then complete the game again, however if you put in a lot of work on that one save file...you might as well just not play at all...because its too much work that you've put into in that one save file...pokemon is a great example, and most of that work you just cannot replicate, like transferring pokemons from one game to another etc.

[@KyleAwsm]

Unfortunately, because of the nature of how SRAM and other forms of volatile memory work, restoring old save data is impossible because the data no longer exists anywhere on the cartridge once the power source for that chip dies. For making a copy of existing data though, in case you want to preemptively replace a save battery (or use the save data in an emulator on a PC), check out my BennVenn Joey Gen3 and Joey Jr. Videos! Thanks for your comment. 👍🏻

[@FroztiProductions]

this would work but I'm certified. You can only solder a board so many times. Instead of adding solder to remove tabs, simply cover in Flux and it will wet just as easily with half the contact time. You're spending way too much time heating the lands. Use Flux liberally. When soldering the new tabs, heat tab and land for a second then feed solder rapidly until fully wet, pull away quick. If you're doing it right you should get it perfect in 4 seconds or less. Clean flux with brush and alcohol.

[@JohnSmith-lh3ht]

As I understand it, Game Boy and GBC carts typically use 2025 batteries, while 1616 is used more often for GBA carts. That being said, you can substitute a 2025 for a 2032, it's the same size but tends to last longer. I don't think you can typically sub a 2032 in for a 1616 though.

[@C-Murph]

Is it bad to touch the solder? Doesn't contain lead?

[@dr.toxicgamingmadscientist]

does cross battery replacing work, meaning you could use the 1616 on a 2025 board or a 2025 on a 1616 board, or would that simply cause a lot of issues or overload the cart itself?

I couldn't even say how many times I've torn my hands and fingers open shoving flathead screwdrivers under those damn batteries when I first started out with this kind of stuff.
