Horribly long load time: it is measured in twelve hours when it is plugged into the computer's USB (this I cit old 2 USB ports, not very powerful either), and at least eight hours the traditional wall socket. The first time, when I loaded the GPS out of the box and I put it all on USB, I had a 24 hour ... The charge itself is not easy to manage: the Garmin GPS 600 flashes when it is charging without indicating, as on an iPhone, for example, it is a quarter, half or nearly the end of charging . So we often find to put in charge without being able to guess whether it is left for 3, 5 or 8 hours of waiting. A tip to the load on electrical outlet I connected the USB cable Garmin battery, supplied as standard, on an iPad charger, and it works perfect (exactly like an iPhone charger). At full charge, the GPS takes the shock, since I'm using it in cycling guide on two days of touring without draining it completely (but with all the sleep options and screen saving enabled, which means that GPS turns off after 15 seconds, for example). Now the question arises cycles: an iPhone battery calculates its life truckload / full discharges and really falters in terms of charging time, after 1000 cycles or more (tested on my iPad 1 who is now 4 years of life, intensive use behind it, and therefore widely thousand loads). Garmin, he does not say how the charger works - I dread the memory effect. In other words, if I do not empty the GPS every time before charging it completely, the battery will "forget" its maximum load capacity and charge less completely. I regret that Garmin is silent on this, and on some forums I understand that the memory effect is, indeed. So I may have bought a battery that will screw up in three years? At least for the moment, I'm happy with my purchase, and to not have to open every time the GPS unit, remove the batteries, put the batteries in the charger, etc ... There I cable branch , finished!
