Got this warning flagged on my Edge1000 yesterday.
Could find Garmin's how to replace the battery but NOT what the battery is..... go figure Garmin!
Want to get it and replace immediatly but need to know what it is rather than open it and then go find a shop that stocks it. The Vivofit battery was a real bi*ch to find.
Thanks
Also out of interest how many miles would you expect a battery to last?
