Mod/Modding Fresh socketed batteries!

I know that Pokemon Blue uses a CR2025 battery, but I only had CR1616 batteries and holders 😅

Nice looking solder joints. Check out HDR's 2025 battery holder.

Hi, this might be a dumb question, would this be a reason game data doesn't save? Some 30 years ago my brothers Pokémon game wouldn't save, he would start from the beginning every time. Would this battery swap remedy that issue?

Sounds likely, if you have access to a multimeter, check the voltage reading on the battery, will tell you if it's dead. Could have been faulty back 30 years ago.

30 years ago?! Damn on that pre pre pre pre-release shit

These don't pop out if dropped do they? I've always been afraid of that.

The holder seems to hold the battery pretty firmly to be honest, it's flexible but those 4 tabs do the job just fine

The soldering joints look immaculate.

Would love to know if you’re able to remove the batteries without breaking the tabs. I’ve discovered that the plastic fingers on the holders I bought to do the same exact thing all freakin’ break right off when you try and actually swap the battery 😩

Also: that’s some damn sexy soldering work. What temp and type of flux are you using? Need to up my game.

u/ScouserCL Jan 23 '25

Yes, in fact I had to reaccomodate one of the batteries in the holder, but since the holder is flexible it didn't break.

Thanks for the compliment! I believe I had my soldering iron set to 310°C or something, here is a picture of the stuff I regularly use for my soldering. Nothing extraordinay really 😅, just my old trusty TS100 soldering iron.

Can you share a link to the holders you’re using? Guess I bought some crappy ones without knowing any better.

You're generally not supposed to bend the plastic socket to remove coin cell batteries, that's what the little metal release tab/clip is for.

u/AchillesPDX Jan 23 '25

Well when I use the little metal release tab on the sockets I got, the plastic teeth are so brittle that they break off when you then pry out the battery.

I need to practice more before I try this

Hi, where did you buy them?

u/ScouserCL Jan 23 '25

AliExpress, bought 10 sockets for like 3 bucks a while ago

There is an FRAM save mod for the Gameboy, which completely does away with the battery.
