The Lanshan is a good car, but the battery doesn't last long. Any advice on how to solve this issue?

Don't leave it unused for too long. I don't drive it every day either. I've turned off the start-stop system, and it's been over three years now. There have been some minor issues, but the battery hasn't been a problem.

My car has been running for four years now with the original battery, and it's still working fine. When did you buy yours? Did you make any modifications?
