PIP battery better than regular?

None of them are older than 7 years, so we just don't know yet. Li-ion cells have a shelf life, so they'll degrade over time even if they're not used. Ni-MH may be a bit more durable in that respect, but I'm not so sure.

 

Li-ion degrade a lot if voltage drops too low

 

Toyota has said the NiMH batteries are better in cold weather. Notice the 2019 AWD Prius has NiMH.

 

Ni-MH is still standard on the non-plugin Toyota/Lexus hybrids, except for a few particular models (e.g. Prius Eco).

 

As far I've been told lithium is latest in the line up but Nickel works better in colder climates.. therefore Toyota have decided to put the nickel battery back into new models in colder climate countries. Ps .. when a lithium battery fails.. the car just dies on the spot.. yet the nickel battery looses power gradually to give indication of a problem so certain sells can be replaced rather the whole battery at a quarter of the whole price. ..with parts and labour warranty of course. Hope this helps.

Absolutely right .. Toyota have even decided to replace lithium models back to the nickel battery for certain countries.

 

i don't think longevity is the reason toyota uses li-on in certain hybrids, and all plug ins.

there are many reasons to use one technology over the other, but i have not read anything about longevity.

 

I think weight is the main reason for the lithium batteries. More power per pound.

 

Li-ion batteries degrade slowly too. Ni-MH cells can degrade to the point that the car won't "start" either.

I do not believe that's true, very few models had Li-ion batteries anyway, and the PHEVs still do - it's the greater energy density with Li-ion that makes Ni-MH unfeasible for PHEVs. Ni-MH batteries for Toyota/Lexus hybrids is the norm, and nothing really changed there.

Battery heaters are standard equipment for certain models in certain markets.

 

Except for model 3 which does NOT have battery heater

 

Well Toyota is not giving us any data about battery life at all.
I feel like Gen3 are doing much than Gen2's but you just have to take my opinion because Toyota is not talkin'. Gen2 had some fixable issues whereas the software allowed the batt to discharge too much , for example upon fuel exhaustion.

 

I thought this was going to be a thread where a PIP battery was installed into a Gen III PRIUS 2,

Very disappointed
