The Garmin Forerunner 10 has been a great GPS sports watch for me. Now after two years the battery life is getting a bit short, so I thought it’s time to replace the battery.
This is not straight forward! Garmin seem to have made the decision that you can’t actually replace the battery on this device. They probably would rather you upgraded instead. If you go through their support blurb, you will eventually get to a “this battery can’t be replaced” answer.
After a quick Google there are plenty people in the same position. Happy with their device, but only wanting to replace the battery.
Not everyone takes no for an answer and a great blog piece has been written by Senix (@Crack3d_l3ns) explaining the replacement process. I’ve linked it here.
After checking out the blog, Senix showed that the original battery specs are:
Brand : ROUTE JD
Code No. : PD2048
Diameter : 20mm
Thickness : 4.8mm
Voltage/Capacity : 3.7v / 120mah
I live in the UK and this type of battery doesn’t seem to be available for sale anywhere!
In the comments section a kind soul noted :
Forerunner 10 mount RouteJD PD2032C1 PowerDisk battery (85mAh 20.1 x 3.5 mm)
A candidate to substitution is Maxell ML2032 (75mAh, 20 x 3.2 mm)
There’s a heap of these available online (eBay & Amazon) so I may try this when the current battery becomes unusable.
