I have a Garmin 705 with the latest firmware (3.30) I usually charge the unit off a standard USB wall wart. Lately I have been getting low battery warnings even just after the unit is charged. I dismiss the warning and the unit works fine. But the battery display also shows low charge despite the fact that the unit will last quite a few hours I'm not sure how many before it will turn off due to low battery.
I reloaded the firmware and did soft and hard resets. I'd like to think it's not the battery.
