You should cut the new Li-ion cell wires ONE AT A TIME because when you cut through them both with one squeeze you were shorting them together through the tool edges. While this short lasts for just a moment, it is still a bad idea. If you tried doing that with an actual "battery" of higher voltage (say a 10S 42V battery) you might do some serious damage to your tool, and it won't do the battery any good either.
I have a 220 and also wanted to replace the battery. Whilst I admire your determination and skill here, it was enough for me to decide to live with it a bit longer then replace
Great video, thank you! I successfully replaced my Forerunner 235 battery afyer the battery life started going downhill. Fortunately though, I didn't need to solder anything on mine!
Awesome video thanks so much! Worked like a charm! Toughest part was to strip/ solder the microscopic battery wires on. My eyes are still bleeding but super stoked about my watch working like new again.🎉🎉
Thank you sir! So helpful,I’m successfully changed my fr 225 battery follow by your video,it’s all good,until the hr and charging ribbon ain’t connecting 😂,but i managed to solve them by open it again and reattached em,thank you again sir! Have a great dah
Love seeing these videos. I replaced a battery for an Ultimate Ears Speaker which was very similar though not as fiddly as the pesky watch. What you come to realise is just how unsophisticated the parts assembly is for such highly branded, high cost products.
Fine video. I tried to repair my watch and followed the instruction carefully. When I switch the watch on the screen was almost dark and unreadble. The functions buttoms was not corresponding to the privios one . I had dismantled the watch before I had ordered a new battery. Maybe if it have been dismantled for one or two weeks the program had been damaged or destoyed. I think no cure is realistic.
That was pretty risky. I watched it like a thriller. Normally you never should work with conductive instruments inside electronics with battary pluged in. One touch in wrong place and your divice is broken. You should use plastic tweezers, nails or something similar (at least put some tape on your tweezers tips) while electronics are connected to power (even if device is turned off). Also you should be super careful not to touch new battery wires to random parts of pcb - that have big chance to fry the electronics. Best workaround I can think of is to glue battary in place then strip only one wire just a bit and solder it on place, then with double care do it with other wire. I would say it's a luck your device ended up alive tbh :) Well done, but please be more careful next time!
If the GPS radio has a hardware failure then you're likely looking at a replacement. But it's possible it's just a software problem. So I would try a factory reset of the watch. Instructions here: www8.garmin.com/manuals/webhelp/forerunner225/EN-US/GUID-FE7137DB-B929-4BD6-B76F-EC5E27AD50B3.html
This is why I have decided not to buy a Garmin watch. Had the Forerunner 965 in my basket and thought what a ridiculous idea to spend $800 CDN and have the battery die 4 or so years later and be in this position.
Great video, thanks for all good tips. When cutting batteri cables, do them individually so you dont short circuit the battery.

Fantastic!
That was really helpful. Thank you. It's great when people keep stuff going long after the manufacturer would hope you would replace it.
Thank you for the detailed information according to which I successfully replaced the batteries on my old Garmin Forerunner 620 ;)
Yay! I'm so happy to hear this!

Great video of the repair process!
Thanks!!
thank you very much for the great video sir..
Very good video. Thank You
Amazing! Thanks for sharing
Very fine, thanks a lot! Also for Garmin Forerunner 235? Only with alkohol and no more? Thanks and musician greetings Peter Bengelmann
My understanding is the 235 is very similar, and is even easier as it shouldn't take soldering!
How it’s going sir?

Can u type out a list of what I need to buy to do this repair?
Hi, thanks. I am not sure where I can get the battery. IUs Toabao any good?
I went on Amazon and searched for "battery Garmin forerunner 225"
Hi... Do you know how to fix no GPS signal on this device?
If the GPS radio has a hardware failure then you're likely looking at a replacement. But it's possible it's just a software problem. So I would try a factory reset of the watch. Instructions here: www8.garmin.com/manuals/webhelp/forerunner225/EN-US/GUID-FE7137DB-B929-4BD6-B76F-EC5E27AD50B3.html
How the new battery holding up now?
Fantastic! I use the watch frequently and it's doing great.
Any chance you know how to change the heart rate sensor ?
Unfortunately no. Good luck! 🤞
Thanks. Is the only way to open taking the front panel or do you know of any other way to access the back part?
@@DogSpaCentroCanino To access the heart rate sensor you will have to remove the front screen.
I guess you have ti change the housing, as its attached to it
Hi Joel. Based on your experience, is it still usable (in a sweaty running condition) after the lcd being opened and reattached ?
Totally! It seems as sealed and water resistant as the day I bought it.
Glad to hear that. Thank you Joel.
Does anybody know pinout of a charger for forerunner 225???
Or on the watch itself VCC D- D+ GND ????
Were did you get your parts from?
Amazon
New screen and battery is about $70 DIY.
can i send you my 225 for battery replacement😊
Impressive !

It’s an easy replacement as the batteries can be easily bought and as shown it’s easy to do.
Now go for a swim, and after, get online to buy a new watch...
