Step 4: Your done!

Put it back together by repeating step 2 (except clockwise). Then put it in your gameboy and turn it on. Start a new game walk outside and save then turn off. Wait about 15 seconds, turn on and if your save is still there it worked.

Enjoy your game! :-)
So that's what the inside of a cartridge looks like...
<p>Very easy to follow your steps to replace the battery. Thanks</p><p><a href="http://batterychargersexpert.com" rel="nofollow">More</a></p>
Could you soder the battery to the prongs in place of the tape for a better connection
<p>Yeah, make sure the battery is clean, try adding a dab of solder, let it cool, put it in place and reheat. I turn my soldering iron temp all of the way up and try not to hold it on the battery for very long.<br><br>The higher temp gives the heat less time to spread over the battery, which IMO seems safer than letting the whole thing get to solder melting temp.<br><br>There's a high chance of error so I don't recommend doing this.</p>
<p>You should be be careful with that since batteries are not meant to be heated.</p>
Thank you!!I bought game secondhand (tricky, tricky!)and found out why!
<p>Recently dug up my old GBC and GBA systems and wanted to replace the batteries since I lost all my saves (and Pokemon!!)</p><p>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 <strong>arvin.barcia's</strong> 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! Everything's working so well I might just ditch my 3DS and Heartgold to replay ol' Silver...</p><p>Thanks!</p>
Would a hearing aid battery work?
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.<br><br>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 &lt;3 Thank you so much for writing how to do this, Josh! I've played every Pokemon Game ever made and classic Silver is still my favorite :D I've had it since I was eight and I'm NEVER giving it up so now I don't have to :D
I got three 2025 batterys for $0.88 at kw surplus
<p>the tweezers worked great thanks for the idea!!</p>

<p>What I did, is I soldered a new battery with small leads to the existing <br> contacts, leaving the original battery in place. The new battery fits <br>snugly inside the cart, and my save file is still there!</p>
I replaced my battery and it saves again, but the clock still doesn't advanced when it's off. Is there something I need to do? Or is just fate?
It's probably a better idea to buy a new battery with the tabs pre-attached and desolder the existing ones on the PCB, then solder on the ones you bought. It'll mean that if you drop your cartridge/Game Boy the battery doesn't fly out and delete your save data.
It's probably a better idea to solder the battery to the tabs on the PCB, it'll make sure nothing goes somewhere it should if you drop the cartridge/Game Boy, and it's not that hard to do either.
Hey guys. It is possible to keep your saves whilst replacing the battery. You just have to leave the system on while replacing the battery. You should try to do it quickly, but still be careful. <br>http://hackaday.com/2012/05/02/simple-trick-for-replacing-game-boy-cart-batteries-while-retaining-game-saves/ <br>(Link has a video.)
Quick tip for removing the cartridge screw. I suggest taking an eyeglasses screwdriver, preferably a flat-head, and inserting it at a 45 degree angle into one of the prongs of the screw head. Then, while pushing down with the screwdriver with the force aimed almost into the screw, (It's hard to explain) turn the cartridge while keeping the screw in place. I think it gives it more leverage or something, it worked for me. Just keep trying, and don't get frustrated.
Thanks a lot! Gonna try it. <br>Note:Don't try it on Pokemon Crystal. If the battery is down you can be sure about that, as the save is OK!
*and the time is not set.
I am THIS close to giving up on my attempt to repair my red cartridge. I followed your instructions to the letter, and did everything you mentioned with the utmost care, and yet, my game STILL wont save! i've tried with both a cr2025 and a cr2032 battery and neither got the thing working for more than one moment. please, if anybody has any suggestions, i'd be glad to hear them. i also have pictures detailing the procedure, but i cant seem to post them.
I just tried to do this with my good ol' Pokemon Silver game and it worked. I used CR2032 battery which was the only thing I found laying around at home. Thank you for the guide on how to do this, it is much appreciated.
I can't open it up eather
i heated up the end (non-blade side) of a plastic knife and melted it into head of the screw thingy, then let it dry and opened it with that. worked like a charm.
I tried doing that, and all i got was the print of the screw in my knife. Did i do something wrong?
Have you tried the advice which I gave to other people? -josh
Your instructable guide worked!!! Now my pokemon gold and sliver game packs work
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<br>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. Thanks! It's now as good as new (except for a dent on the back from the drill, which I don't mind at all)
hey one of my tabs broke off now wat am i suppose 2 do ??? it wont work any ideas?
you need to solder it back on :( . You MIGHT get away with gluing it however the only difficulty is you need to maintain an electrical connection. i.e not block off the current with a thick layer of glue. -josh
I had the same problem. So if i solder it back on then it will be ok?
Yes it will, just make sure not to damage the circuit board when you're soldering it, though.
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. <br><br>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.....<br><br>
Plan B: there's a conductive electronics cement that seems to work just dandy. I found my tube at gateway electronics ( www.gatewayelex.com ) but I'm sure it's available in many electronics stores. Gateway is just the electronics/electronics surplus that's closest to me.
Worked like a champ thanks Josh!!
im struggling to open the cartridge, is there any other easy eays to open it?
Just get a plastic pen like a bic and remove the ink section. Jam the smaller end into the screw and it should be able to be unscrewed.
This worked for me. I had to dig around the hole with a screwdriver to get the pen to fit in, and after that, the pen tip worked much like a screwdriver. The screw was loosened first just by scraping at it with a screwdriver. I took the ink tube out of the pen and used the short casing.
all you have to do is get a 3.5(it may be 3.8) mm gamebit screwdriver from amazon and then your set the cart i have tested it on and work are n64 games and the expansion pack for it and gbc games
Thanks for posting this! I'm excited to have my copy of Silver up and running again! Gotta catch 'em all!
I'm a little stuck - I unscrewed the game and got most of the tab off but it seems to be attached really firmly in 2 small points, which I can't for the life of me get off! Is there some special technique to this, I've tried using tweezers a screwdriver and a razorblade and nothing is making it budge even slightly :(
It's spot welded. You have to break through the metal around the spots. There's really no other way.
Hi, i cant remember perfectly (because it has been a fair while since i actually did this) but i do seem to remember there being a tough bit as you describe.<br><br>I was able to get the tabs off by firmly pushing the screwdriver underneath the tab (possibly twisting the screwdriver as well).<br><br>If you are still having real trouble with this, it might be possible (depending on how far up the tab the hard bit is) to actually cut the tab off the battery, and simply tape the remainder of the tab onto the new battery?
Thank you so much! My old Silver game now works like a dream. I couldn't find anything small enough to remove the screw, though. I had to improvise with a specialized plier.
i honestly just made an account so i could comment on this to thank you. it wasn't as easy as i expected to do this, but if a 17-year-old girl can do it sitting in her pajamas then anyone can. thank you sooooo much!! :D i can't wait to start playing! n_n
