Ruined my watch… The battery connection socket ripped off with the battery connector…
I have taken apart phones and laptops in the past without issue, so I am not inexperienced by any means. I was as careful as possible.
Excellent guide - thanks! My Fenix3 wasn't charging any more so following your guide I replaced the ‘dead’ battery with a new one with ease. However, when reassembled, the new battery worked but would not charge. I took it apart again, and found slight corrosion or gunk on the motherboard terminals where they contact the inner side of the charging pins. After a good clean with meths and a cotton bud I popped the original battery back in, reassembled it, and hey presto! it started charging! Very happy!
I appreciate the guide as my Fenix 3 after 6 years of owning it could barely make it 24 hours without charging it.
The only thing I’d add to the guide is that you can reuse the adhesive from the existing battery as it’s only double-sided tape. Other than, it went flawless!
Thanks for this. Just did it successfully. A quick note, when you are separating the battery from the motherboard, it pulls up/perpendicular to the device and not parallel to it as I had initially thought. Luckily I did not break the battery connector to the motherboard. When I put it back in I needed to push it towards the motherboard to properly seat it. Look closely to make sure no part of the connector is sticking up, even a hair or it will not work.
Worked perfectly! Thanks a lot
Nice guide, thanks. However after battery replacement the watch dont switch on anymore. When it is connected to the charger appear on the screen battery 100% and time but, when I disconnect it stay off and dont react to the buttons commands. Anyone knows what could be happen? Thanks a lot
Mine does the exact same thing. It no longer turns on. It says battery 100% on charger but as soon as I remove it from charger it turns off again and won’t turn on.
I noticed some glitching happening after I changed my battery. In my case, loosening the T5 screws that hold the motherboard worked (I guess I had too tight). Good luck!
I have the same issue, did anyone find a solution to the not turning on and 100% on charger issue?

The battery I received from iFixit doesn’t work. When I tried it, the watch does not turn on. When I put watch in the charger it comes on and says "Battery 100%” but as soon is it’s unplugged from the charger it turns off again and is unresponsive. I put the old garmin battery back in and it works again. Will be returning replacement battery to ifixit.
Aloha! Not difficult at all. Thanks for the great instructions and pictures. I’d add one note: when putting the T5 screws back on the motherboard make sure they are not too tight! My watch started glitching and showing the logo randomly. I reopen the watch and loosen it a quarter turn and it is working fine now. Also, I did not pull the screen ribbon but was careful and it worked fine.
Garbage, now watch doesn't work at all. Build computers for fun/hobby, whomever classified this as an easy repair is full of it. Both removing the battery and trying to reattach the ribbon cable are extremely difficult. Now that I am done, nothing, no screen, doesn't work period. Thanks for taking my money, wasting my time and lying about the ease of use of your product.
Top job. reiterating the above comments of Michael Reid re battery plug removal/replacement and suggesting the guide would be flawless by adding the above comments at the appropriate picture. I experienced the "100% charging issue and failure to turn on" following my first reassembly but on reopening it is was clear i had left the battery connector plug not quite seated.Thanks very much.
Easy to follow. Fixed my watch.
