Gen3 Prius 12V Cost?

[Grumpy Cabbie]

How much does the gen3 Prius 12v Battery cost and what are it's specs? I've heard the ah should be 42ah, others have said 38ah, and yet others 36 or 35ah.

What is correct? What is the official part specs and costings?

[kithmo]

The Prius+ has a 45Ah one,

I don't know the original Ah of the Gen 3, but http://www.eurocarparts.com do a Bosch 40Ah one for £44.11.

Your information does not agree with the attached document, the OEM Battery and as far as I can tell the replacement are not AGM and Prius Gen 2 had two different sizes of Battery!

I've found that the gen2 has a different Battery to the gen3.

That's why I'm struggling to get the info I need. Whenever I quote my car as a 2009 I get quoted for a gen2. If I quote 2010 I get told it doesn't apply to my reg number. Grrrr. Rock and hard place.

So, does anyone know the factory specs for the gen3 2009, 1.8 Prius?

My post covers the correct specs, Toyota sell the same Battery part # 28800-YZZPD for both MK2 & 3 Prius

Just for reference the factory part number for a RHD UK MK2 is 28800-21170 which is replaced by 28800-21171

MK3 RHD UK Prius used 28800-21171

Both are now replaced by Optifit part # 28800-YZZPD

[Grumpy Cabbie]

In that case thank you and I think we've also found the problem affecting the new Auris HSD's.

The Auris HSD has a 35 Ah 12v Battery.

The gen3 Prius which is 95% the same, has a 45 Ah 12 Battery.

I'll hold back on saying there is a design fault with the Auris until I've seen more information, but it's certainly looking that way. Owners all over Europe are having significant issues with failing 12v's on the Auris HSD.

[Devon Aygo]

Could well be the case as the HB & Tourer Auris MK2 use different spec batteries, The HB has a one off Battery only used by it, the Tourer uses a similar but different Battery which is shared by Yaris HSD and multiple other non UK Hybrids.

Are the cases we are seeing all Hatchbacks? As we don't seem to have an issue on here with Yaris HSD

P.s I'm sure someone with a Tourer will pop up and dispel my idea, lol

[Grumpy Cabbie]

I believe it's just the Auris HSD new shape.

Someone posted a pic of theirs on the PC forum and it looked quite small, smaller even than the one in my Prius.

The Prius has always had a problem with the 12v. They don't have to turn the engine over so are small, but they run a lot of computers and take a while to top back up as the charger system isn't as strong as an alternator.

I wonder if the engineers in the UK who designed it calculated that 35 Ah was enough to power the accessories, but forgot to take into account that a hybrid 12v takes longer to top back up. A few deep cycles and the 12v will fail very prematurely and then the cars suffer the problems they're having.

If this IS the reason for the failures, then it's not a cheap fix for Toyota.

[RunningInPleasePass]

It's looking more and more likely that to sort this out we need to have a bigger Battery fitted to Auris Hybrids, as you say "not a cheap fix for Toyota"

I'm sure Toyota know what the solution is but will be very reluctant to admit it?

[Grumpy Cabbie]

Is it negligence on Toyota UK's part? Is it a design fault?

It's looking much more the latter or maybe both.

I'll quote Mr Wong from the PC forum who advised the following;

Thanks for posting the photo of the Auris 12V Battery. As previously
discussed, that is rated at 35 Ah and happens to be the same Battery as
was installed in the Classic Prius (2001 - 2003 model years.) A
similar Battery was installed in 2G Prius without the Smart system.
That battery was marginal for those installations and it is not
surprising to hear you are having trouble with that battery in the
Auris. A much larger battery sourced from Panasonic was subsequently
offered as a replacement Classic 12V battery, which required the battery
bracket and cabling to be replaced.

The 2G with the Smart system and 3G Prius use a 45 Ah, S46B24R battery
which is physically longer to provide the added Ah capacity.

Sounds like this issue has a history and Toyota UK didn't do their investigations correctly when designing the Auris.

Quite clearly the capacity was increased to allow for the higher drain of the keyless system, yet this has not been included in the Auris.

Toyota are a UK success story but that doesn't give them carte blanche to not correct a clear issue. If they do the recall now, they'll keep their reputation. Delay or ignore it and it'll ruin their hybrid reputation.

With that Optifit model priced at 348.50 EUR, having Toyota supply and fit it for £90 is a bargain. :)

Not if you're replacing it every 2 months as is the problem with some owners at the moment!

This is true, but in this case it wouldn't cost you anything as it would be replaced under warranty.

I was thinking in the case of a 5 or year old Battery outside of warranty. :)

Under warranty? From Toyota? Dream on...

I only got mine changed, because the DP authorised it, Toyota still don't admit any problems.

Apologies my post has been amended to reflect that the info relates to UK RHD only, also removed the AGM reference as I cannot find a defenative answer some spec's say yes others say no

Thanks. It is a little disappointing that getting the technical information accurate and reliable from the source (i.e. the manufacturer Toyota...) is so difficult.

I don't know if it's AGM but my Battery has the Pb (lead) warning sign on it, could it be lead acid ?

[Grumpy Cabbie]

An AGM Battery has lead in it too.

http://en.wikipedia.org/wiki/VRLA_battery

They're generally safer and used inside the passenger compartment. That way if someone stuffs into you from behind, you're not all going to get covered in acid! They vent less too - important as you don't want to be breathing in the fumes. (there is usually a vent tube).

But there are some shortcomings too as outlined in that link above. They're more expensive, can be damaged easier with overcharging, and cost more.
