Forerunner 405 410 405cx Problems
Forerunner 405 410 405cx Problems

I have repaired over 5000 forerunner and edge devices so rest assured that the repair will be of the highest quality. Trust the experience, don't go elsewhere!  If I can't fix it, it can't be fixed!  I will refund your $$ if I can't fix it.

Does your Garmin Forerunner only last a couple of hours or less?  Well it's not going to get better.  These are high quality high capacuty replacement batteries.  

My testing shows training time up to 10+ hours and 2 weeks in power saver (time only) mode with the new EXTENDED battery.  The 405/405CX owners manual lists ~4 hours in Training Mode (page 40).  I have successfully repaired 405s with the continuous reboot problem, so if you have that problem I can fix it too!  The standard Garmin battery is rated 300mAh but performs more like 200mAh.  This battery is rated and performs at 350mAh!

I need spare parts, so I will buy your broken 205/305/405s etc too; don't throw them away!  

Bid and buy with confidence, I will stand behind my workmanship and products.  If you have ANY questions or concerns before or after your purchase I will make it right.  Check my feedback! I have done this repair on Edge and Forerunner 205/305s for hundreds of happy customers and have now expanded to 405/405CXs too.
