While you may have other issues (ignition switch, charging system, etc.), I really think you need to take a hard look at using one of these light weight batteries in a daily driver; these light weight units are designed for off road use, but are being marketed for street use; often advertising electrical output (CCA, reserve amps, etc.) that is measured using non standard methodologies (if these batteries were tested under BCI specs, they are actually much weaker than they claim). These light weight units are simply not designed for, or capable, of normal street usage.

We have had more than one customer install a light weight battery, only to shortly encounter all kinds of electrical and electronic “gremlins”, ranging from Litronics that would not ignite, to weird displays on the OEM electronics, and intermittent electrical issues (starting problems in both cold and warm weather, dim lights, stereo systems issues, etc. In most cases, we could find no organic issues with the car, the light weight battery failed a standard load test, and the problems went away with the installation of a correctly sized battery.
