Any of my co-workers would give me a boost, but I was working super-late today, so they’re all gone, and there’s nobody else in the industrial complex here. AMA says it’s “hours” 'till the guy with the battery in the truck gets here, so… hello hours of bleary web surfing.
Hmm. I’m starting to think I’m better off walking out to a bus-stop, if they’re still running.
My car is a 1996 model, which I bought in 1998. I changed the battery for the first time in early 2007.
It hadn’t died, but the car was in for other work and the guys tested it when the car was off and said it was only about 25% charged or something like that and he didn’t think I should keep it too much longer “just in case”. He was shocked to find out that it was a 10-11 year old battery (I know it wasn’t changed in 1998 because I was getting the work done at the dealership who sold it, and they had no record of it either).
My husband’s company has 24-hour on-site security, and they have a portable booster in their office, as well as cables in the security truck. You should suggest something like this for your company. Heck, my previous company also hired out a crew to shovel cars out of the lot when they are snowed in at the end of the work day. Gotta be prepared in Montreal winters!
We actually boosted another employee last weekend, who didn’t know that security could have helped him, and who was freezing his ass off in -25C weather+wind waiting for someone to come along on a Sunday and help him!
I’d get someone to check the wiring to your cigarette lighter. Every car I’ve ever driven was built so that the cigarette lighter was only powered when the ignition was at least in the “accessories” position. The only way that the seat heater should flatten the battery would be if the car was left with the keys in and switched to “accessories” or “on”.
If the battery was flat and the keys weren’t in the car I would suspect that the battery finally gave up the ghost and it had nothing to do with the seat heater.
I seem to recall that my 1980-something F-150 would power something through the cigarette lighter even if the keys were out of the ignition. I would always have to consciously unplug things before leaving the truck or else the battery would die.
ETA: Maybe it is only a feature of newer automobiles?
