HV battery

And why do you want to do that horrendus thing?

 

I would be astonished if you could. Totally different chemistry and physical size. Not to mention all the interesting things the car's computer might say about it. LOL! All for a stupendous downgrade? But really, I am curious about your reasons.

 

no. did the battery die, or are you just concerned about the future?

 

Concerned about the future

 

It should last for many years and lots of miles. I would not worry too much about it. But, I don't see how you could put a regular Prius battery in a PiP. The system wouldn't know how to handle it. I'd suggest enjoying it for as long as possible if you already own it. There's a fair chance the battery might outlast the rest of the car.

 

The answer is not, with out doing MAJOR modifications

 

if you already own the car, i wouldn't lose any sleep over it. 5 years and no battery issues reported here. if you intend to keep it 10+ years, there may be a failure sometime in the future. a salvage might be available at that time, or remove and repair.
if you haven't purchased yet, and it's too much concern for you, stick with a lift back, there's no way the small lift back battery would work. the chemistry is different, the software is different, the hardware is different, even the motors are different.

 

It would be extremely difficult, because you would need to change many systems inside the car. It's not designed for this at all and it would be far easier to replace the bad cells in the Plug-in battery and repair it. But nobody I know of has refurbished one of these batteries.

My theory is that when the pack loses its power, it will still have more than enough capacity to function as an ordinary Prius and it will likely outlast the vehicle.

This car's Lithium Ion batteries wear out when they remain charged for a long time, when they're depleted, and when they're subjected to heat, especially when charged. Toyota designs the system so that the batteries are never more than 80% charged and never less than 20% depleted. Since Jordan can get very hot, some good practices:
1) Charge when it is cool, like at night.
2) Don't leave the car charged for long periods: Drive it and use up the charge.
3) Ideally, use a timer so that it charges at night such that it finishes charging in the morning, right before you drive to work. There is a timer in the car that you can set which will do this if you wish.
4) Don't use the HV button to "save" battery capacity for later.

It's best to charge and drive right away. If the battery is empty 80-90% of the time, it will last longer than if it is help charged 80-90% of the time.

No Prius plug-in owner I know of has had a battery fail, so my advice is based on LiIon technology in general.
