| Aug 18, 2016 at 8:26 | comment | added | I have no idea what I'm doing | @tahwos How is this even a stress test? The charging system should easily handle all the accessories turned on at once. If it stopped doing it's job whenever you turned on heated seats, heated rear window and the AC at the same time then the people in colder climates would be quite pissed. | |

| Dec 9, 2014 at 2:49 | comment | added | tahwos | You're over thinking it: a 6 year old battery is probably ready to be recycled. And, deliberately turning on as much as possible, to "stress test" your charging system, is just irresponsible. Your car's charging system is designed to "top off" the battery, and run a reasonable amount of accessories, wile you drive - NOT to be a full on battery charger. A properly working and properly used system, will normally be around 14 volts at the meter (while running) - any higher or lower, indicates a problem, or too much load. | |
