Hybrid battery.

[Graham Austin]

As my 2010 Prius is 12 years old the hybrid Battery is not as good as it was.  I had a recent Battery health check which it passed but as I intend to keep it for several more years I may need to replacereplace .  Are the newer lighter Lithium batteries offered as a replacement?  If so what is the cost?  Thanks.

Graham, quite some time back I read that a replacement hybrid Battery in the US was iro $5,000 not including labor (sic). Not sure if that was EV or HEV 

Do you really think Battery replacement will be a sensible option? You can replace a 12v Battery in the market place as one spec battery will fit many models.  I don't think hybrid batteries, other than at cell level, would be as interchangeable. 

The sum of the parts of a new car will be huge compared with the costs of the car. 

This is true for most electronic goods.

The hybrids don't need large amounts of Battery capacity so even if the pack is degraded a bit it is still useable, unlike EVs. I wouldn't bother TBH unless you also want to do some sort of PHEV conversion for it.

Toyota don't sell 'upgrade' packs, so it'd just be replaced with the same pack, but there are third parties that sell lithium upgrade packs in the USA; I don't know where you can get them here in the UK tho'!

Yeah, that’s right no upgrade available,  just a new Battery. What is your mileage on the car? How do you know that your Battery is not as good as before? What make you think about it? I believe a new Battery for gen 3 hybrids cost around £3500 from Toyota and it’s the best option. There are some traders on eBay selling new battery that look real oem Toyota for around £1000 but that’s hard to believe it’s true and I am not sure I will trust some electricians playing with my car . Battery module can also be replaced but once you start doing that it might turn into endless game of trouble. Best to evaluate situation and decide whether to proceed with new genuine battery or just keep driving the car as is until dies completely.

Is the car eligible for hybrid Battery warranty if you had a dealer service done? I think mileage is a condition but not sure if it's under 100k or 150k. Car would have to be throwing fault codes though to warrant replacement

My Battery seems like is running low often when is hot and the AC demands more power to cool off the cabin. I remember it was the same with the new Priuses I was driving in the past has always been the case with all Toyota hybrids. I am not sure though if after the years and miles done my Battery has lost a chunk of its potential and can’t hold charge as much as before but either way I am driving it until dies completely and the car refuses to drive, then will think about eventual change or repair.

I beleve  hybrid Battery needs to fall below 70% for it to triger repair under warranty.

You can always check its air filter to see it its dirty. The one for the Battery of course.

The funny thing is hybrids are far less affected by Battery degradation than EVs are - It has a minimal effect on their range and efficiency; The fact that my Mk4 can get 80+mpg on a 0.7kWh Battery just shows how little they need to operate!

Good shout about keeping the filter fan clean tho' - That seems to be the number one cause of premature traction Battery problems.

[Roy124]

The hybrid charge/discharge is controlled by the system.  The EV Battery is controlled by the user.  That report recently that 2-3 rapid charges a month is OK and that a 13 amp home charge is best shows there is scope for better user management to preserve Battery performance.

So, the Battery has been Toyota tested and deemed it passed the test. So why do you say the Battery is not as good as it was???

ps. Graham has not visited the forum since 9:57 Sunday morning. Perhaps he will be back this weekend.

It's like comparing apples and pears, the operation and demands are quite different.

The EV Battery is holding 100% of the energy for a journey so any reduction in capacity immediately affects range.

In a hybrid the energy is from the petrol, the Battery is used to optimise the running of the engine, so a bit of capacity loss has a lot less impact. The capacity of the petrol tank is unchanged, the thermal efficiency of the engine is unchanged, but the running is perhaps a bit less optimal than when the Battery was new.

That’s true and make sense to be. Toyota hybrid batteries seems to hold  very well their health. I am getting best mpg ever with my car although is close to 220000 miles and 12 years, fully stock car with most of its parts still original. There is one mod, a smaller 16” wheels and narrower tyres but that does  not affect efficiency by much. So far so good 👍⚡️⛽️

Yup!

I can certainly help with Battery degradation problems
