Are you sure you don't have a marginal battery (about to go bad)?
I once had a problem where my battery wouldn't hold enough charge to
start the car after sitting for two days. Upon removing the plugs and
looking in, I noticed that one of the cells looked different - like
corroded or degraded. The battery would probably test fine, but was
really marginal. I put a new Interstate in and all the problems were
I guess the lesson is don't trust 100% on the portable battery testers.
You must also do a visual inspection of the internals of the battery.
