On Thursday's commute home, my CD player kept cutting out on me.
"I guess that's normal for a 20 year old 10-disk changer playing a burned CD", I thought. (What's a CD, anyway??).
Yesterday morning it did it again. I wasn't too concerned until I realized it was happening with each application of the brakes. Huh? I pulled up to the next stop sign and heard a low drone of a vacuum pump ("bwaaaahhhh") instead of an eager hum ("bweeeeeeh") and realized that my accessory battery was pretty much dead. Not too concerning until I remembered that this battery powers the main contactor.
Well, I made it to work without a hitch. And I charged that battery all day long with a real battery charger (it consumed a lot of current). I think it has been falling behind the main pack due to my shortened summer charging events (the more efficient warmer temps require shorter charging times). Also, my four year old plays in the car often and leaves interior lights on and whatnot. Yeah, that'll do it.
