This is a 350mAh battery. My testing shows training time up to 10+ hours in "training mode" a full day with "GPS on" and 2 weeks in power saver (time only) mode
This is a very common problem on the Edge 205 adn 305. Riding along and the unit shuts off for no apparent reason. Unit will turn back on and work normally. I install a hardware fix for this. It is a permanent fix, unlike using spacers and other poor advice out there on the internet.
If you damaged your display, I will replace the LCD for you.
This battery is rated a bit higher than the stock battery and performs better than the stock battery. Garmin Edge Garmin Forerunner 305 205.
Used but in good cosmetic and working condition. Includes the clear plexiglass screen. There may be some scratches, but viewing area will be in good shape. The rubber buttons may show some signs of wear, but will be intact and not leaking. I will send the best cover I have in stock at the time of shippment.
