The RIGHT Way to Replace Gameboy Advance Cart Batteries

[@IamRegularPerson]

First time using a soldering iron and I used this tutorial to replace Pokemon Emerald's battery. Very useful tutorial with some in-depth knowledge about the carts too.

[@matsstrmsli6178]

I'm actually in the exact same sitation and need to replace the battery in my pokemon emerald game as well haha, what a coincidence. Though i haven't started the process yet and honestly don't know if I'm going to because the process seemed overwhelming to me.

[@50zezima]

@@matsstrmsli6178 Me too lol. It's a good game that's why. I bought one on the market and was worried about it being a fake, but turns out I just got a really great deal on a legit Pokémon emerald with a dead battery. Works for me! I lost my game a long while back and had to buy a new one and lost that somehow as well. this will be my third one which won't be lost anymore because I don't have sibblings living with me

[@PatientZERO100]

I'm in the same boat with my Ruby edition. Once the batteries arrive I'm gonna give it a try, until then I'll have this video on repeat lol.

[@Chr1s887x]

Can someone tell me , my battery has also run dry but I have my saves (Pokémon Ruby). If I change my battery will my saves be gone ??

I gotta say...holy shit. This has to be the most straightforward, easy to understand and pickup, while also being the most thorough guide I've seen. Some monumental congrats you to my friend and thank you

[@danpluso]

Nice tutorial, this is pretty much all the steps I do and it gives good results. One extra step I do that helps is to tin one of the pads first before dropping the battery down. Then use that tinned pad to tack the battery in place. It stops the battery from moving around when you have solder and an iron in your hands like at 5:53. Then I finish up the other tab, then return to the "temporarily tacked down" tab and apply more flux and solder to finish it off. I also bend the tabs down (on GBA) and found a 45 degree bend works best.

[@rasubosu355]

Thank you You are one of the very few who talks about soldering properly

[@hanes2]

I for whole my life until recent month thought liquid was bad, so I never used things like flux.

[@TDAdvocate]

If anyone watches this more recently, this does not fully fix the Pokémon carts. You actually need to have a way to manually adjust the RTC on the cart after the new battery is installed. This is because replacing the battery sets the date back to the year 2000 so time based events are still frozen until it reaches whatever year it last read before the battery died. You can also fix this by just restarting your game from scratch but using 3rd party software and hardware is the only way to save your save file properly after replacing the battery. Otherwise this video is perhaps one of the most definitive tutorials out there for replacing a battery properly. Thank you very much for making this amazing video!

[@RobertPaulson87]

I've just bought myself a copy of Fire Red and haven't started a save file yet. Am I best off changing over the battery before starting the game to avoid any issues later on? Thanks

[@TDAdvocate]

@@RobertPaulson87 From what I understand, you can either change it or wait to see what happens. If you bought it from someone and they can tell you they replaced it recently then you are good. If they haven't then maybe consider doing so. But honestly I am not sure if Fire Red actually needs the battery the same way Ruby/Sapphire/Emerald do.

[@colt0864]

Fire red and leaf green don’t have batteries

[@LRM12o8]

@RobertPaulson87 if it had a battery, yes. But since only the Hoenn games use a battery, you're fine. For Ruby, Sapphire and Emerald you should definitely replace the battery before starting a new savefile, if it's still the original battery. Those games are 20 years old now and if I recall correctly, I heard somewhere that the manufacturer expected those RTC batteries to last up to 15 years!

[@dashiellgutierrez2326]

I have one question My friend, first after all, excellent video, but i need tour help, i have a metroid Zero mission, that lose the saves, so automatically an electronic guy change the battery but still without save, Even he Will test with the legs (sorry i don't if i can Say that with this Word) of another Game that saved Game with the same way, but nothing, so My questions is what could be happen to this cartridge? Sorry if My English is not the best

I'm no slouch when it comes to soldering and electronics, but this is, without a doubt, the most thorough tutorial I've seen on both the batteries AND the fake cart epidemic that's been going on for over a decade. Absolutely fantastic job, good sir!!

[@andrewmcallister7781]

Mate, this is an epic summary of everything you need to know about doing this repair

[@DnoSauce]

This was first time using a Soldering Iron and this tutorial was soooo good. So clear at what to do and was nicely paced and easy to follow. I can report that I no longer get that “Internal Battery has run dry” error anymore. Time based events WILL OCCUR!

[@luismata2814]

i heard that doesnt fix the daily events on ruby/sapphire/emerald can you confirm this?

[@Phantomknighttv]

@@luismata2814 you can check by going to the lottery and see if it changes.

[@muckersTGN]

Great tutorial! Getting the batteries to connect properly over the chips can be really tricky. Also, props for mentioning flux - so many neglect it. The first time I replaced an internal battery (for Pokémon Gold) I used the first KZbin tutorial I could find. It showed basically ripping the battery off the tabs and holding a new one in place with electrical tape. It was a terrible idea! Constantly slipping slightly out of place and losing my data... Don't do it, kids!

[@helchin93]

Such a great rundown, and I was prompted by the game clock message on sapphire so I’m super stoked you covered that in the video. Good to know I don’t have to worry about wiped saves, may eventually still replace it but this is great!

[@cheapergamer]

Great tutorial! For anyone wanting to backup their save before switching batteries, I can personally vouch for the GBxCart RW. Just a heads up for those who are doing pre-emptive replacements.

[@KyleAwsm]

Thanks so much! I try to promote my friend Bennvenn's stuff wherever possible, so just including the obligatory post here for people to see: Check out the Joey Gen3 and Joey Jr. as well for save backup. Another battery wired in parallel temporarily works too. Cheers, and thanks for watching! 🙂👍🏻

[@nebraskabirdwatching9521]

A DS or DS lite with an R4 or other flash cart can also back up GBA saves with a homebrew program.

[@audunjemtland8287]

You explained exceptionally well. And what a soothing voice. Amazing tutorial. Thanks a bunch!

[@RE4PER]

I'm doing this exact method for my Metroid Fusion cart as well. Thanks for the amazing tutorial 👍

[@dav3yb]

I've been doing quite a bit of digging into how the RTC works on the pokemon games recently. Even if you replace the batteries in Pokemon R/S/E, most clock based events wont work. The main issue will be Shoal cave, which is only accessible during low tides, so if you have a dry battery, it's best to set the initial time to one where low-tide will be present. The next thing would be growing berries, which probably won't effect many. When the battery is replaced, the RTC is reset to 1/1/2000 and 00:00am. This is also the case when starting a NEW game in Ruby or Sapphire, where as Emerald just updates the time set, and not the date of the RTC. The way the game deals with growing berries is to count time from the last save point, and check to see if the value is greater. Since the last save is probably pretty far into the future from the year 2000, berries will basically never grow. There are some homebrew apps that can run from either a GBA or DS flashcart and access/update the RTC. It can get pretty convoluted, but if you really want to update the time on the games after installing a new battery, using a $10 DS flashcart and the homebrew app is really easy, as it'll just read the RTC from the game in the GBA slot, and allow you to edit it.

[@rohan1864]

I don't think I fully understood. The game counts time from the last save point, but what does that mean if you reset the game's clock to 1/1/2000? Do you mean that it takes into account the date at which the previous save file was last saved, meaning that if I had a save file that I last saved in 2012 and then started a new game, that save file from 2012 would still be some point of reference for the new game? If that's not what you meant, I don't really understand how it works. When you wrote that the game "checks to see if the value is greater", could you specify greater than what? I'll be very grateful if you clarify, mad respect to you for digging into this and sharing.

[@seowjingwoon]

You are talking about the infamous berry bug right? That can be fixed if you have a copy of the newer pokemon games like FireRed/LeafGreen/Emerald. Basically involves connecting 2 GBA with a link cable and update the game using the Berry Patch included in those games. It only affects certain batches of Ruby/Sapphire.

[@renandstimpyfreak672]

I don't know why I'm having so much difficulty replacing the save battery in my copy of Pokemon Sapphire. First time soldering, and I've tried three different batteries from two different battery manufacturers, and it's still not working out. I've even tried using an external save editor to restart the RTC after installing the battery, but it's still not clearing the error. I will try and get my hands on a multimeter to make sure all the batteries I bought are still even good, but I'm starting to get worried that I'm really doing something wrong. I do appreciate the tutorial though, it's super helpful! When I do get my multimeter I will be sure to reference it again!

[@flamespear86]

Wow, I thought all GBA games had flash memory. This is a very informative video.

[@starlacUK]

There are about 30ish games that use Sram (2% of the GBA library), the vast majority used non-volatile forms of save (eeprom/fram/flash/passwords). Pokemon Ruby/Sapphire used flash memory with the battery being used for the clock.

[@bland9876]

I was taking pics for a buyer and saw the battery in a non pokemon game that definitely didn't have an RTC so I was so confused. That led me to look up this video.

[@ozmond]

It’s mainly for clocks. They aren’t technically “save batteries” in most cases.

[@itsmatt517]

Yeah, I did too. My Metroid Fusion cart has a battery, but my Zero Mission does not for example

[@ZebraScout]

Kirby nightmare in dreamland for example has Fram or sram, just depending on the model, this KZbinr straight saying that sram is most common is incorrect

[@overdriver99]

thanks.. I learned alot regarding different saving types of GBA cartridge.

[@doutchebags]

Warning: certain events in Pokemon R/S/E are tied to the internal clock proceeding past the time where the previous battery died. However when replacing the battery the internal clock resets to January 1, 2000 (halting certain events specifically tied to what day it is like berry trees, but not things tied to the clock simply moving forward like the Umbreon and Espeon Eeveelutions). In order to fix this you need to modify the save data so the internal clock is set to the correct time. Then all time based events will work properly without any issues.

[@stephen7862]

How do you modify the internal clock itself?

[@doutchebags]

@@stephen7862 i believe it requires a ROM dumping device (a cartridge reader that connects to a computer) and a save editor. There was a video on it that showed off exactly what to do, but I don't remember what the title of the video was.

For some reason, my - side on Pokemon Emerald was extremely difficult to remove. No amount of heating or desoldering braid allowed me to separate the pad on the board from the battery lead. I tried pulling it away by force, and unfortunately pulled away the whole solder pad. Don't do what I did, kids. Luckily I was able to still solder to the tiny little hole marked - right next to the pad, but just be careful everyone.

[@SuperSpyMario]

I have a question regarding the soldering iron temperature you used for the soldering process. The reason is, I don't want to pull out the pads by mistake due to putting an incorrect temperature setting in Celsius. Edit: I found a comment for the temperature setting you replied to and you said just above 375 degrees C. But unfortunately for me, I have 99.3% tin and 0.7% copper wire.

Good tutorial. I have a question. This could also be made for placing a battery holder for coin cells instead a soldered cell? In GBA cartridges there isn't much space left.

[@ZyferWarriorPrime]

I've seen it done in GBC carts, but the limited space in GBA doesn't make it very feasible. The most I can get in there is a CR2025 and it is a difficult fit. A holder for a CR1616 would be impossible. If anything, you'd have to find an even smaller holder and battery and reduce its capacity.

[@HarmonicWave]

I looked this up because my Pokémon Ruby battery is dead/low so I got that message in game about the clock, but my game save file is totally fine with all my Pokémon. I don't know about soldering (I'd have to buy all the stuff) but maybe I can get someone else to do it for me. Thanks for helping me to see what needs to be done in so much detail.

Since you emphasized that it should be a temperature-controlled soldering iron, what temperature do you recommend setting the iron to?

[@rigama4442]

I have an issue with my Pokemon's Sapphire RTC. I've already replaced the battery myself the same way as explained in the video. The dead battery message doesn't show up and you can configure the time without issues. However, it just stays at the same time doesn't move at all. I used an RTC reader app on a R4 cartridge to edit it with pkmn chest as well to prevent the berry glitch, which shouldn't be a problem either since I have FireRed, Leafgreen and Emerald to link with. The only thing that makes it "work" is adjusting the RTC manually using the RTC Reader. It's worth noting that I did all of these previous procedures with Ruby and Emerald and they are working just fine. It's just Sapphire that's presenting this particular issue. If anyone knows what may be wrong with it, I'd gladly appreciate it.

Just curious, other than Pokemon GameBoy Advance games, why do some GameBoy Advance games contain batteries? For instance the two Metroid GBA games contain a battery, but the Super Mario Advance games do not. However, you can still easily save game data on each game? Or the 2nd Densetsu No Stafy game contains no battery but 1 & 2 both do. Kinda of sucks because it causes more of a headache to worry about losing game data and saves.

[@GrianyBunch]

Since I’m to scared to open up my PS3 and try to fix the clock problem, it felt like a good idea to see if maybe I could practice and try to repair some of my game boy Cariges since they kinda don’t work and since there small for my DS....but after this it makes me resize EVEN MORE that...I’m not a repairer and have no idea what this stuff is and probably would mess it up anyways, starting to feel stuck on how to fix when I know I can’t and I really want to sell some but I can’t if they don’t work probably...so I’m pretty lost. But this I guess is progress of kinda learning?

[@andipajeroking]

Question: You use the braid to clean the pcb and apply flux to better help the cleaning?

[@KyleAwsm]

I solder by the mantra "clean, flux, solder, clean" - The flux is to help the solder bond with a metal surface by removing oxidation from that surface, which would otherwise make it harder to get solder to "stick". This goes for the solder pads, wire, components, AND the copper braid itself. So yeah, more or less the flux helps to clean the surface of impurities that would otherwise make soldering more difficult. 👍🏻 Thanks for watching!

I can get a CR2025 in a GBA cart. Takes a little work, but you can do it. The Metroid Fusion I have has no battery, one of the few games where there was ones with a battery and ones without. The Pokemon ones are likely the ones you will see depleted most because of the Real-Time clock.

You're like an ancient blacksmith forging japanese katanas. Can you make a video about "differentiating clone-false games and consoles from original ones"?? The force of nintendo be with you.

Great video. One question though. When the battery dies, is the save in sram also gone? or does it just lose the ability to save new data into it?

[@KyleAwsm]

When the battery dies, the save data is also cleared. Thanks for watching! 👍🏻

[@NinjaTenK]

Tip to doing this put the soldering on first then the battery it’s easier if the way hard for you

Bit late to the party but would it not be better to get a cr1616 battery holder in stead of a tabbed battery?

I noticed there were two official versions of the Metroid fusion pcb. One with an internal battery, and the other with a flash memory chip. I had eBay sellers unscrew and open the carts for me and send pics of the pcb to me before purchasing. Until I found a Metroid fusion with no save battery. Obviously there are also fakes out there which have that glob of silicone.
