Without the solar panel plugged in, it sits at 12.6 volts after 24 hours. I check every time I get in the car as I have USB charging sockets with a built in DVM so I see the voltage every time I turn the ignition on.8 years is a fair stint for a car battery, but you keep them topped up, maybe some manufacturers are more sensitive/tolerant than others
Have you measured the load voltage on the 8 year old lately?
