plug in battery

unbolt the battery case, get some big strong friends or an engine hoist, and have at it!

you're in missionary territory, all the best!

(service manual probably details the procedure)

 

Ok, I'll byte which battery ... The little guy in the corner or the big honkin one?

 

uge, really

make sure to disconnect the safety plug

 

#desertdeals69 your profile shows Gen2 Prius. Is that the car you are asking about? Does it have a plug to charge the traction pack? If yes what kind of plug?
If you're asking about a different car, what car are you asking about?
If it's just a regular gen2 prius than that shouldn't be as difficult as it would be if there is a plug to worry about too.

 

your battery is normal. i would suggest it is a (very labor intensive) exercise in futility.

 

I'd be very interested in any and all you're willing to share, if and when you do the pack swap.
I had a 14 PIP for a couple years and still remember some of the differences between the prime and its
predecessor the PIP. I was the 350 something member of the blizzard brigade here at PC. I can see myself attempting a Prime pack swap one day in the distant future, possibly. if I live that long.....

 

Turn off the AC, then check the estimated range

And remember it's an estimation based on previous journeys, it is not a useful indication of battery SOH in the slightest.

 

go look at techstream. I'm sure hoping you've heard of it.

 

My PIP maxes out at 10.6 miles. I am very conservative driver.

 

you need a new battery

 

There are plenty of trick one can use in a PiP to up the EV estimate. And one has to describe their own definition of conservative driving in detail for context. I agree that an guessometer topping at 10+ EV miles is
awful. In my 14 I used to get 12 in the coldest days of winter. But I would also drive in creephome mode 5-8 mph for a mile than under 35 for another mile to get the electric components warmed up sufficiently to keep the ICE from switching on at single digits F degrees and lower.
ie describing how you define conservative driver is important.

 

Anything over 10 is good for me
Totally depends on driving conditions and other factors. And as I said, not a reliable indication of battery health.

 

True. For me it means tires at 46/44 psi. Not using a/c. Slow acceleration. Anticipating stops so to use brakes as little as possible. Choosing secondary roads over highway. Driving below the speed limit when traffic allows, around here that generally means about 40 mph. Reminding the drivers behind me that the speed limit sign is for maximum, not minimum.

 

i average 14 in decent weather, just tootin' around town, it's a great little errand runner

 

QuantumFirebird and Bisco are better references than I am. With my PiP I wanted to learn all the EV I could absorb and had the 999.9 mpg bug all the time. So the computers were filled with EV only miles and reflected that data on the gauges each time the car was driven.

 

if possible, document the whole job with pictures and commentary, that would be very helpful to the community, as some will likely need a new battery in the future.
