GM claims it will do 2 miles straight EV mode alone in the user manual
from the original user manual printed in 2007..'
another good indication for a weak battery is a poor translation from battery to engine mode. when normal pressing of the acceleration or 29mph mark..
it should be a seamless... switch over. no lag or hang time...

this happened to me on an suv i test drove nearly caused an accident as I was not expecting this to happen..
it was a 2009 4*4 with 115k miles on it.. I think the battery was damaged from sitting on the lot too long..
115k should be in good working shape..
did not buy since it would have blew the budget since the service 4x4 was on and the battery needed replacement.... they were asking 13,500 for it 14,900 total

I test drove a 2012 with 94000 miles and it ran fine it had other issues i was not interested in fixing it would have put me WAY over budget.. ( oil sensor issues ) it was 15,600 total

LOL

"Depending on the state of battery charge, the vehicle can travel up to two miles in EV mode." This is meaningless as a measure of any kind. It's even disqualified at the outset: "Depending on..." Here's that that sentence really means:

"If you manage to drive the SoC to the absolute maximum of the usable range, which is almost impossible with normal driving, and you drive like a kindly old grandmother with no surplus power consumption, you *might* get 2 miles of pure EV mode."

There are multiple other factors that can cause "poor transition" that have nothing to do with the hybrid system.

"115k should be in good shape" - based on your experience? Based on how you think things ought to be? Have you seen the data posted on this site? No one has ever posted any meaningful data that says their battery is okay at any mileage.

I just had a 2008 Prius battery fail at 55K miles. How do you explain that? According to your wisdom, it "should be in good shape."

Anyway, at this point we're just polluting an otherwise useful thread. I suggest that once you have something meaningful to bring to the table, start your own thread.

battery that went flat duh aka left un-used

it happens with lead acid batteries... that is why when you buy a new one you want it to be fresh ..


and on the 4x4 I test drove it had issues staying in auto stop while parked it had been sitting on the lot for a month.. some sucker bought it a week after..
the battery I have was replaced at some point s/n L02XK

My record on a flat road in slow traffic is just over 7/8 Mile EV. Barely using the pedal to go, mostly creeping.

2 miles down 3% grade with tailwind maybe
