This instructable shows you how to replace a battery in a pokemon gold/silver cart. If yours deletes your save and won't let you save anymore then chances are you will need to replace the battery.

This may work with other gameboy games but pokemon gold/silver are the only ones I know about. Please Note: I take no responsibility for any damage to you, your gameboy, your game or anything else. My game and gameboy are fine and this shouldn't damage them, Just covering myself. Please note: if you have ANY type of save that loads up then this will wreck that, otherwise lets get started EDIT: quadcam24 has suggested in the comments that instead of using a screwdriver you could use fine tipped pliers to turn the security screw, this method would be easier and quicker than using a screwdriver if you could find pliers with thin enough tips Step 1: You Will Need. I did this a while ago so you can see the battery already replaced but you can get the idea.

Take the precision screwdriver and push it from where the tab is stuck onto the battery near the outside in towards the inside therefore removing the tab from the battery but keeping it attached to the pcb. Repeat on the tab stuck to the bottom of the battery. Stick on the new battery with the tape making sure to get good contact between the battery with the tabs. If that comes loose then your save gets deleted:-( Note that the battery goes in upside down (see the polarity markings on the pcb) Please do not solder the tabs onto the battery as this is very dangerous and could cause the battery to explode Step 4: Your Done! There is a much simpler and permanent solution. A mildly modified cr2032 surface mount coin battery holder should be soldered into the solder points where the original battery was soldered in. This way future battery changes will take seconds and not require additional soldering.

It also should be fast enough in the future that your save games will survive, although you can always backup and restore with a retron 5. This battery fix works on nes, snes, n64, gameboy, gameboy color, and genesis carts. I have not tried on other carts as if yet, but as long as there is clearance only minor mods should be needed. Correct me if I'm wrong, but wouldn't JB Weld be an option? I understand it doesn't conduct electricity, but the current should flow nicely if you make sure the direct connection from the battery to the tab is good before applying JB Weld.

You can find it at a local hardware store pretty easily, should only be about $5. Just make sure it dries fully before closing the game up. Of course this is a more semi permanent solution and won't be as easy to replace the bay again should you need to (compared to tape). Video Broadcast Scheduling Software Free. Don't do it this way. Yeah, it works, but it's not worth the risk.

It's very easy to damage the board or case using the techniques (and I use that term loosely) illustrated here. It's not hard to do it the right way, and a proper security bit to remove the screw is not expensive. It's two soldering points to remove to take the old battery out, and two points to solder the new one in. If you don't know how to solder, give it to someone that does. There are only so many copies of these games floating around, and destroying a copy by pulling stunts like this isn't going to make them easier to find.

Recently dug up my old GBC and GBA systems and wanted to replace the batteries since I lost all my saves (and Pokemon!!) I just followed your guide and it worked like a charm! I was infuriated at not being able to open my Silver cartridge with a flat screw driver, nor finding the right tool at my local hardware store.so i stumbled across this post and arvin.barcia's hack comment with a melted pen case that worked so well the first try I couldn't believe it. Then spent a good 20mins detaching the metal tabs from the old battery before replacing it and neatly and securely fastening it all up with electrical tape!

Zte Mf 821 Mac Driver. Everything's working so well I might just ditch my 3DS and Heartgold to replay ol' Silver. Just did this earlier this afternoon!

Worked absolutely awesomely:D Used tweezers to unscrew it (it took a few tries but the whole process was only about 15 minutes) then used a flat-head screwdriver to break the tabs off of the old battery. Getting the one underneath off took a little bit more work because of the angle but it popped off eventually. (For those of you having trouble, kind of slide the edge of the screwdriver underneath and push down as you move it forward. You don't have to worry about scratching the battery so dig into it as much as you can and the solder should scrape off.

I also did a little bit of rocking back and forth as well as side to side in order to jimmy it under further.) Then I placed the new battery in, folded the tabs back into place, and layered it with a ton of electrical tape. I'm pretty sure I got ripped off on the battery (it was 7.50:/) but I wasn't in the mood to go hunting for a better deal or order one online. It still ended up cheaper than ordering a new game on ebay and now I have my childhood memories back. Awesome guide. I had used it once already to fix pokemon silver, and then some time later got my sisters copy of pokemon gold.

The first time I got help from my dad, and we struggled a bit with getting the screw out, but ended up just trying to drill it loose from the cover. The drill was right next to the screw and ended up spinning it, finally making the screw loose:P Just picked the metal bits off the battery with a flat head screwdriver and taped the new 2032 battery in with insulation tape. The 2032 battery along with the tape ended up making it a bit tight, so we ended up not having to put in a new screw afterwards. Both copies now work perfectly.

It's now as good as new (except for a dent on the back from the drill, which I don't mind at all). Fwiw, I recently replaced the battery on a pokemon sapphire. In that the battery was also soldered down. It was fairly easy to desolder and I bought a replacement CR1616 at Batteries Plus and they were able to spot weld some solder tabs onto the new battery for me. And before anyone worries too much about the price, don't.

It was cheap. I don't recall the exact amount but we are talking $3-5 range for the battery with the tabs spot welded onto it. Of course I still had to solder it down, but I am confident that my repair will last as long as the battery. It was dumb luck that I realized Batteries Plus would provide that service. Yes, frustrating that Nintendo didn't use a holder that was meant for user servicing, but at least it wasn't that bad of a fix! If you don't solder and feel like taking a chance, you may be able to get someone in a local high school electronics class to do it for you.
