Some Love for the Auxiliary Battery System
Now, with the auxiliary batteries, I'm just not worrying about it. The PC just has to come out of standby, so it's ready right about the time I get my seat belt on. There's no time waiting for things to happen; I have navigation in moments, so I can put in my destination before I even get rolling; I don't have to multi-task, fooling with the nav system as I settle into driving.
Josh has a full-blown dual-core monster under his seat, and an Optima auxiliary battery. His system is ready to go in a flash, and will live on Standby for so long that he hasn't had it shut down since we got it all installed.
These cars are both daily drivers, so they get a lot of use. But, even if they were in use only a few days a week, the battery systems would be must-haves for both of us.
