I have two batteries in my trailer, about 3 years old, charged by solar panels. Since installing it appears, I'm getting about 5 minutes a day of use. I get an alert saying "Battery low" at the end of the day and "Battery dead" in the morning. So I documented several times. Low battery warnings come about 3-5 minutes later each day and low battery warnings come about the same time earlier. In my area we are currently gaining about 2 minutes with earlier sunrise and later sunset due to ground movements. While I didn't notice if it was sunny or cloudy, there were a few days where I seemed to gain about 8-10 minutes a day from general use. I may update later when I try to document the weather more. . Of course, on cloudy days I don't get as much solar charge, which affects the time.
