So far so good. I am an RV Tech, and use this to power RV slide outs and automatic leveler systems, have had no issues as of yet. Seems to hold a charge pretty well.
I bought these to put into a car that I getting ready to sell, I bought them because of the price. When I got them I could not believe that nice quality that they are. I wish I wold have bought a set of these for my new Equinox instead of spending $$$ on a set of Weather Tech floor mats.
