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.
