2009 is only 9 years old. That’s pretty common life for 12V lead acid battery. Prius is more demanding on the 12V battery but mostly only if it’s sits for long and is only driven short trips. So I’m sure that there are still some people with original 12V battery on their gen 2.
Probably, but they're pushing their luck. I think the average 12V battery in Florida lasts about 4 years. I envy your climate. Sure, it gets cold, but you can dress for that.
Normally people envy the other way around. It’s hard to dress for something like -30c or -22F… And with cold weather you get road salt so everything in a car is rusted.
Yeah, I hate the road salt. I used to live up north. I find it hard to dress for 98F with 85% humidity. You can only take off so many clothes. LOL! But I admit that -20 or -30 F is mighty uncomfortable to say the least. Not to mention the long winter nights you have. Maybe we should figure out a way to have your summer and our winter.
I only ask because after reading this I was curious.. http://www.toyotanation.com/forum/906-camry-6th-gen-hybrid-2007-2011/1428074-2010-camry-hybrid-12v-battery-life.html I think we have a wider audience here and I have heard such claims in the 100,000+, 200,000+ and 300,000+ threads here. I don't expect I'll get a response now. After all, who wants to be considered stupid or foolhardy.
I'm pretty sure mine was on the original 12v when it was replaced last June during the 120k major service. There wasn't a record of it ever having been replaced by the previous owner and the car did have pretty thorough service records. I didn't actually see the old battery to read the date on it but I instructed the mechanic to change it if it was over 5 years old. He indicated it was still the original so it had gone 9 years. If I still have the car I'll replace it every 5-7 years. No reason to push it and wind up stranded in the middle of the desert or in the middle of the country somewhere.
In a typical gasser, the battery gives you a bit of warning. (Even then lots of us get stranded.) Usually no warning with the Prius, although mine did make its condition known with slow accumulator pump pressurization.
In this topic: 2006 Prius Inverter ( It's Not the Inverter) | PriusChat there still seems to be the original 12V battery in place:
