Not uncommon. The 12V aux/starting battery is tiny, and the car has a pretty high key off drain. According to Van Battenburg cars were going dead in airport parking lots quite often after just a few days. >I'm curious, is that a separate regular 12V battery, Yes, a group 51 The main pack can charge the aux battery through an inverter, but the software wont let the main pack drain below a set discharge. > I'm just wondering if he's in for a hell of a bill A little under $200 will get you a 46 AH optima (OEM is 28 AH IIRC) although I am not sure if this would void the warantee or not... caveat emptor! Some Prius owners are quite the zealots about them, and there is a ton of info on the forums, here's 2 that apply: http://priuschat.com/forums/gen-ii-prius-main-forum/9271-replacement-12-volt-auxiliary-battery.html http://www.techno-fandom.org/~hobbit/cars/prius-12V/ HTH Ben

I would talk it over with the nearest battery distributer or Prius club member before I dropped $200 on one of those tiny things. > > The battery is a more or less dealer only piece because of it's odd size.

The software gives numerous warnings to keep the driver from over discharging the batteries, including 'limp-in' modes with reduced speed in extreme cases. The NMH batteries are a pretty mature technology. The car treats them with kid gloves...no over charging or deep discharges. 1 fellow has 2 RAV4 EV's and both are at about 100,000 miles and well over 10 years trouble free, still having good power and range. There is already an aftermarket in repairing the packs. Rarely would all the individual batteries wear out or fail at the same time. They are tearing them down and replacing just the bad cells. I've heard of folks getting back on the road for about $200 HTH, Ben

Thanks for the info, I'm pretty ignorant of the technology. I'm thinking they're using lead acid batteries. :-) > There is already an aftermarket in repairing the packs.

No transmission, no head gaskets, no timing belts, no heads, no spark plugs, no fuel pumps, no radiator. Imagine that, cars that are easy to repair! :-)
