Hi there, I wanted to take some time to react to this video. I watched this video after ordering a new battery for my Edge 520. As you can imagine, I got a bit scared to proceed and change the battery. I figured I had not much to lose and a new Edge 530 isn't super expensive, so I proceeded SUCCESSFULLY. What do you need: -Hairdryer -Plectrum alike prying tool Key to success is being patient. It took me about an hour with the extra over subtile aproach. A third hand fot the blowdryer is also pretty helpful. I didn't really pry, but used the plastic plectrum to only make cutting alike movements. Hardest on the corners. Every cut you will hear the adhesive crack and give up. Take your time, be subtile and you will be successfull. Thanks for this video as it made me extra carefull and might have saved my display. :)
Ha Ha, yea I need to replace the 520 battery and am extreme electronics guy. What I am not is patient........used them for years time to try a cheapo amazonsmile china sub. Their all made over there anyway.
Thanks for this - appreciate you showing that it’s actually quite difficult to get open! Mine cracked, but little lost as the battery was not holding charge. I will still try to do the fix - thanks for all the gotchas!
I pried off the screen with small metal flat bladed screwdrivers before seeing your video -- I got lucky, no damage to the screen. I ordered a battery and hope that fixes it.
I always try to keep my devices at 20%-80% of charge. This will dramatically extend the health of the battery over time. When I know I won't be using it for more than a week, I'll keep the charge at 40%-50%. If I know I have a long ride coming up, I'll ping it to 100% because it'll suck if your Garmin dies mid-ride. Had the 500 for several years and it still holds around 80-90% of it's full charge capacity.
I bought a used 520 today with a weak battery, thought, this will be no problem like my Edge 500, damn thing won't come up and I screwed up a bunch of pixels in one corner, so mad at myself, but seeing this video makes me feel less incompetent, sigh, and SIGH! good to read the comments on how I can get it apart though, gonna have to be real real careful now to keep the screen intact!
I really wish that Garmin had just used screws to assemble the 520. We live in an era when a sophisticated electronic device is considered "disposable" when the battery reaches end-of-life; I hope that will change as the pace of mobile technology plateaus (Moore's law is tailing off) and we become more conscientious about electronic waste.
@@BikesBlades Agreed! its kind of unbelievable that such an expensive device was assembled with the idea that battery would be non serviceable. The edge 500 I have came apart with no issues, this is another entire ballpark, same idea with some cell phones of course, disposable technology but with often a 1000$ price tag, ludicrous! Audi V8's come to mind as well, timing chain on the back of the motor, never really intended to live much longer then the initial lease period. Thanks for making this video, really appreciate it! :)
I think the problem is that some of these battery suppliers make videos that imply that anyone can do these repairs and it persuades you to buy the parts. I have had very similar fail results with the iPad mini so I know exactly how you feel 😢. The video I saw for the 820 from new power doesn’t show using a heat gun and also says all tools included and a few seconds into the video tells you tools not included. I am also an electrician with 40 years experience and managed a fail. I have also done a successful battery replacement on an iPhone so not all bad. I think any device with a glued in display will require a heat source to remove. Thanks for the video.
You hit the nail on the head. I wish Garmin wouldn't manufacturer cycling computers that can't be serviced... Battery replacement seems like such an obvious thing. I guess, on the other hand, if the battery does after a 2-3 years, it drives sales of newer cycle computers/GPS devices.
Newpower99 now has a battery replacement kit for the 520 including a spudger to pry open the screen. Just saw the instructional video on their channel.
i bet they didn't use the spudger for the screen though as it came off way too easy in their video and the gap around the screen is not wide enough to accomodate the tool. I used heat with one of those mobile phone screen suckers and a razor blade to seperate the adhesive and re-installed using T-7000 glue
had a similar experience with my edge 530! the connector for the screen came loose after i dropped it, causing the backlight to go out. after a year and a half i disassembled it and reconnected the screen. I didn’t have any adhesive so i just reheated it and thought it was fine. Anyways, I went on a rocky mtb trail and the screen flew off, causing the connector to break in the process! now i think its toast...
The Edge devices are not designed to be serviced. In addition to sealing and securing the display glass lens to the case, There are many other aspects of the design that are unlikely to survive the process of opening the unit... for example, antennae contacts can easily be disturbed or contaminated, and the flex circuits a fragile. That's why Garmin replaces units rather than attempting to repair them. Once they been opened, it's almost impossible to get them back to 100% reliability and performance.
I had an 800 that was run over by a car and they replaced it for the out-of-warranty fee. Right now I have a 520 plus with a damaged pin on the micro USB connector. I am trying to figure out if I can find a connector like that. Replacing the connector isn’t what scares me. It’s taking off the case.
Yes, I've done surface-mount solder rework on the mini-USB connectors on Edge 500 computers, but the problem with the Edge 520 is just getting the case open, and then closed again. Garmin will do an out-of-warranty replacement on the 520 for $99, I think - so that's one option.
Thanks for the tip! Recently I was replacing battery in my mobile and the new mobiles are also glued (I guess this applies to a lot of new electronic devices). For that you have to use the heat gun to melt the seal. The thing is that to put them back together you should put new gasket/seal/glue. Im planing to get the Egde Explorer and already getting prepared on how to open it in the future :) I guess they used the same method as there are no screws.
You can have Garmin do an "out of warranty" replacement for $99 (last time I checked). But of course, you can also put that much toward an upgrade, or switch to a different brand... I really wish Garmin had closed the case with some screws to allow service.
I was successful at opening with minimal damage to the screen. Put in replacement battery, it works but won't charge. Stays on 9%. I don't have an electronics background but wish i understood why it's not worked. Just seems wasteful to replace not repair. Thanks for the video.
That's very strange... Even though I am an electrical engineer, battery management is its own science. My suggestion would be to leave the Edge 520 on until it goes dead completely, then recharge from that state. As an aside, I once went for a ride after updating the firmware on my Edge 1030... I started the ride at 87%, and it steadily increased to 100% over the course of the ride. Power-cycling fixed it, but it was weird while it was happening.
I returned my broken Edge 520 to Garmin as an "out of warranty" service in 2018, and for $99 they sent me a brand-new Edge 520, which I then sold for $150 and used the proceeds to buy a new Edge 1030. My advice in 2024 is to retire the Edge 520 and upgrade to an Edge 540.
I feel your pain. Mine is getting a bit older and battery isn't what it was. I guess I'll eventually send it to Garmin. They must do replacements. In the mean time I'll use my external battery for longer rides I guess.
The secret to opening this is very simple: take your wife's hairdryer and warm the thing up. Or leave it on some hot (60oC/140oF) radiator for an hour before doing this. And don't use metal tools for this. The best tool for this kind of disassembly is guitar pick. Official Sony Ericsson (yeah that old phone company) tool for disassembling cellphones was called "SE Guitar Pick tool" and was literally an orange guitar pick with SE logo on it :). Although to be fair - the start of this screen removing will be the trickiest part as you need something sharper to begin the process.
I broke my 520 screen accidentally some months ago. I made a phone call to the Garmin technical service and they told me that the warranty did not cover the breakage of the device (logically). They change the broken device by another one (reconditioned). I had to pay 180€ for that new device and they gave me six months of extra warranty.
MTB vidvid - OK, I'm thinking about doing the same thing. I think for me in the U.S., it's roughly $100 for an out-of-warranty repair. But that's worth it to get my 520 back in service! I bought an Edge 1030 in the meantime, and I really like it, but the 520 is more compact.
You can mount an auxiliary battery (like a lipstick style USB recharageable) to your stem and power your Garmin 520 while riding. I've gone all day with backlight at 100% and the 520 always ends the ride at 100% charged. This may be easier than trying to change the battery!
I actually have the Garmin extended battery. The difficulty I had was that most of my mounts block the USB port on the underside of the 520, so I could only use the extended battery on one bike that had a Garmin "Out Front" mount with a bend in it.
You suppose to start from the top then down the side on the left then around!! You have to open it slowly little by little moving along!! If you had the little plastic tool moved slow you should crack a screen but you started from the side mmm that's much more difficult. Pitty man!!
The truth is, even if you can open a sealed Edge device without breaking the dsiplay, it might not ever work well again afterwards. I returned my old Edge 520 for a new one, and it only cost me $99.
@@BikesBlades Not bad cost its not hard to open, and it will work well after you replace a battery. I have done it already, if you have butter fingers maybe! Its not hard to do actually many people do this all the time everyday without breaking anything
the rubber buttons of my garmin 520 just cracked and broke. Ive found sources to purchase the back cover and the battery... and I just come across this video...... and..... should I or should I not...... 😣😣😣
I hear you! For what it's worth, Garmin will do "out of warranty" repairs on the Edge 520 for $99 or something like that: www8.garmin.com/support/outofwarranty.html My advice would be to NOT attempt to open the case. :)
I used 3 inch wide 3M double sided tape and was able to cut it nearly perfectly to get a watertight seal. As a backup, I also put on some automotive clear silicone sealant on the crack between the screen and case. I rode 2 hours in the rain yesterday, and it still works!
Yes - lift up the amber-colored Kapton/polyamide tape, then lift the black part of the connector, opposite where the flex circuit enters. Use your fingernail - it swivels up to a 90-degree position, and the flex circuit will drop right out.
Thanks for sharing....I’m thinking my battery is reaching its end of life. Will check with Garmin if they can replace the battery and save me the hassle of trying to take it apart.
...probably what I should have done! But I do take some pride in being able to fix electronics. I don't understand why Garmin made the case a permanent assembly.
Hello Dejan - I posted the battery part number in the description or comments a while ago. This video is a couple years old; I replaced my Edge 520 last year, so I don't have it to check the physical dimensions anymore.
@@BikesBlades nowhere to find the exact dimensions of the battery, i would put in another battery of higher capacity... just the battery part number. thank you anyway
@@DejanBakic well, if you are planning on replacing the battery anyway, the first step is to open up your Edge 520. Then you can measure the battery yourself.
I know, I know. Sorry! :) I opened the computer off camera before I even knew I'd make this video. The main point I'm trying to convey now is that there isn't a good way to get the 520 case open. My original plan was to open the computer, identify the battery, get a replacement, then film the process of soldering it together and closing it up again. I knew I was in for trouble when I couldn't find ANY fasteners on the outside of the case. In retrospect - it would have been entertaining for you all to hear my reaction when I realized I had cracked the screen. Hindsight is 20/20.
Oh no! I'm sorry to hear that. What I ended up doing was sending my broken 520 in for a $99 "out of warranty" repair, then I sold the replacement unit for about $150 to recoup the investment.
@@BikesBlades thanks, that is a good idea. So they replaced it even though there were signs you cracked it open? I was looking on aliexpress for a replacement screen but I think I'll break more things than fix it.
@@mecharoo If you pay the $99 for "out of warranty repair," Garmin doesn't care *what* you did to it. :) I pretty much told them exactly what I did in my description when I returned it. I might have even included a link to my video.
nikkiesteban yes, I thought of that after the fact. It would probably help, but then you'd still have to figure out a good way to reattach the screen to the case when it's time for reassembly. The bottom line is that the Edge 520 is not something you can DIY a battery repair/replacement.
Sorry for the slow response! Here's the info: Rechargeable Li-Ion Battery, 1ICP7/32/41. Rating: 3.7V, 700mAh, 2.59Wh. Garmin 36100043-00. Made in Taiwan by the Joules Miles Company.
Thanks for the video B&B. Made me go careful and was successful with no heat, slowly sliding the pry tool and picks supplied by 99batteries. For the speaker two vids showed soldering direct to the speaker and two showed soldering the old and new wires together. Using the existing solder on the speaker seemed simple enough but I proved my lifelong ineptitude with soldering once again when I first managed to trail the two solder spots together. And by the time I was done trying to fix that I had no solder at all on the center part and no success getting any to stick, even with flux. I did manage to get the back of the case hot enough to be glad I didn't melt the mount. So now I have a new battery and very silent 520. But at least it works otherwise
Ah, OK! I understand now. Sorry to hear you had trouble with the speaker wires... I use a stereo microscope to do that kind of fine soldering at work, and it's still difficult.
Update five months later - Was getting about an hour per 10% battery life but the last couple of rides dropped to 25% / hour so it looked like I'd be charging it every ride. But now the micro usb connector doesn't like any cord so I can't even charge it. I tried to make it last but I guess it's time to move on

What do you need:

Key to success is being patient. It took me about an hour with the extra over subtile aproach. A third hand fot the blowdryer is also pretty helpful.

I've ridden over the Pennybacker bridge many times.
I moved away from Austin, so now I just have fond memories of the dam loop.

You must heat the screen before try to pull it off, check other videos how to. have a good one
Yes, in hindsight, that would have been a better technique.
Thanks for sharing. Useful info
Thanks Antony! I hoped it world at least be entertaining. Schadenfreude and such.
One of the bottom buttons failed. Broke the screen trying to open it with a screwdriver.
I'm sorry to hear that. I really wish Garmin had just assembled the 520 with small screws. "Disposable" electronics are so frustrating.

@@BikesBlades thanks, that is a good idea. So they replaced it even though there were signs you cracked it open? I was looking on aliexpress for a replacement screen but I think I'll break more things than fix it.
@@mecharoo If you pay the $99 for "out of warranty repair," Garmin doesn't care *what* you did to it. :) I pretty much told them exactly what I did in my description when I returned it. I might have even included a link to my video.
Maybe you should heat the glue with heat blower?
nikkiesteban yes, I thought of that after the fact. It would probably help, but then you'd still have to figure out a good way to reattach the screen to the case when it's time for reassembly. The bottom line is that the Edge 520 is not something you can DIY a battery repair/replacement.
Bikes & Blades re heat the glue again if you're about to re-assemble. Same process when dismantling new phones?
It's not really glue, holding the screen into the case/body - it's more like an adhesive gasket.
may I find the battery model information?
Sorry for the slow response! Here's the info:
Rechargeable Li-Ion Battery, 1ICP7/32/41. Rating: 3.7V, 700mAh, 2.59Wh. Garmin 36100043-00. Made in Taiwan by the Joules Miles Company.
Heat only the edge of the screen!
nikolaos stavrou Yeah, I think that would have helped. I was feeling bold, so I just went for it. ;)
Battery Success but Speaker fail
Thanks for the video B&B. Made me go careful and was successful with no heat, slowly sliding the pry tool and picks supplied by 99batteries. For the speaker two vids showed soldering direct to the speaker and two showed soldering the old and new wires together. Using the existing solder on the speaker seemed simple enough but I proved my lifelong ineptitude with soldering once again when I first managed to trail the two solder spots together. And by the time I was done trying to fix that I had no solder at all on the center part and no success getting any to stick, even with flux. I did manage to get the back of the case hot enough to be glad I didn't melt the mount. So now I have a new battery and very silent 520. But at least it works otherwise
Ah, OK! I understand now. Sorry to hear you had trouble with the speaker wires... I use a stereo microscope to do that kind of fine soldering at work, and it's still difficult.
Update five months later - Was getting about an hour per 10% battery life but the last couple of rides dropped to 25% / hour so it looked like I'd be charging it every ride. But now the micro usb connector doesn't like any cord so I can't even charge it. I tried to make it last but I guess it's time to move on
You should of used your hair dryer
Yes, I think so!
