Can I damage the watch.?...
I know from experience that the battery life of the garmin405CX isn't brilliant. I usually charge mine twice a week. What I am wondering is- am I doing any long term damage by charging the battery before it is completely flat?( I know with laptops- the lifespan improves if you only charge it when the battery is low)
Tonight I have 34% battery left; how long would this last for a run? I plan to do 10m tomorrow at 9:30 pace. Is 34% enough, or should I charge it tonight. I have had the experience of the watch getting the "low battery" signal and then going dead during a long run- which I want to avoid
apart from this i think it is a great bit of kit.
Been topping my 405 up for the last 2 years, battery life is still around the same as when I brought it.
My wife's 405cx battery completely failed during the snowdonia marathon and hasnt worked since. Useless for a 2 year old watch. Mine has just done the same thing. Utterly unreliable.
I must admit I've never used my 405 as a normal watch, so haven't thought much about its battery performance outside of a run.
When it was new it would just about manage a day cycling- about 8 hours with 6 or so hours actually riding. Now I get nervous over 4 or so hours of cycling. But that is loads for running.
I do charge it every day though.
Idiot question please. My 405 only stays charged for a little over 3 hours now - annoying when it lost the end of my one and only marathon. Is there any way of replacing the battery or do I need to contact Garmin?
