Recently, my FR10 started to restart mid run while on GPS. I thought it was just some random glitch. So I did the hard reset and it was back to factory setting. This time, even though the battery indicates its full it would constantly reboot on itself. I tried software updates and more factory reset. Still the same results. I came to conclude that my battery was not holding a charge anymore. I searched online for replacing battery in a FR10 but it was not user replaceable, so they say.
Since I live in the Philippines (Cagayan de Oro City), by the way I bought the watch in the US, it would not be cost effective to have it sent to the US just to get the batteries replaced. I sourced locally and the local watch repair shops would not service or even open the watch. :(
Maybe you are here because of the same problem. But before you do this, understand that this will void your warranty and it is in your own risk for doing this and it may damage your device.
So lets get it on...
Before you open your device you should have bought the replacement batteries first.
Brand : ROUTE JD
Code No. : PD2048 (click Here for ROUTE JD website)
Diameter : 20mm
Thickness : 4.8mm
Voltage/Capacity : 3.7v / 120mah
You can buy it online for about 10-20USD.
1. Torx T5 screwdriver
This is all the tools you'l need in opening you watch.
1. Unscrew all the 4 screws at the back of your watch. Unscrew opposite corners. While unscrewing, push firmly with your fingers the back panel.
4. Once secured, set aside the back panel and turn over (right side up) the watch to remove the watch assembly. The battery is beneath the gold plating and you need to pry the 8 latches.
5. Do latches 1-6 (red) to remove the green PCB & screen and then latches 7-8 (blue) to remove the black battery housing
8. Assemble the watch doing the steps in reverse
And here's my watch plugged in.
Let me know in the comments below if you made it. :D
