Cost of 12v AGM Battery for 2018 Prius

@DaveWR just in case you missed it: do check out the above link. @Elektroingenieur is the Naz.

 

I picked one up at NAPA last month and it was on sale, It cost me $120 and they gave me a free tool bag and a roll of shop towels. They also loaned me the tools and I changed it in their parking lot so I didn't have to deal with the core charge.

 

the 2015 or earlier took an AGM battery because it was sealed. The battery was inside the car in the rear trunk. If you were in a wreck, and upside down trapped in the car, the battery acid could not leak out on you and burn your skin. Gen 3. AGM cost mort than lead acic batteries.

Gen 4 (2016 or newer) puts the battery back in the engine compartment under the hood, like other cars. ,. Therefore you can use a vented, old style lead acid battery that is cheaper.

If you want to save some money, get any of your batteries from a junk yard.

I am on my 3rd Prius, having totaled my 1st 2

 

Batteries from a junk yard are often.......JUNK.
That is not generally good advice.

And even if you don't need an AGM type battery, they almost always last longer.
I personally think they are well worth the extra cost.
YMMV.

 

i would like to know more about this. do junk yards pull the 12 volts, test them, and sell the good ones?

 

Yes, particularly in newish cars which are totalled - I've never done it, but considered it once. The others get recycled.

 

Toyota uses a Yuasa AGM battery that lasts really long (7-10 years). But the price is not more than $300. You can shop around using google and buy it from Online Toyota Dealership with a clear address and location. Many Toyota Authorized real dealerships sell parts in eBay too. Just make sure you check the address and phone number of the seller. Search: HJ-S46B24R in google and you will find an online retailer for about $200 shipped. Unfortunately, other brands besides Yuasa and Panasonic AGM batteries are not as durable. Some people have good experience with OPTIMA Yellow top but some don't, Optima is a mixed bag. The OEM Genuine parts is Yuasa, renamed as Truestart by Toyota dealership with a sticker. The OPTIMA battery has wide variations of internal resistance and if it is not exactly the same as Yuasa HJ-S46B24R, The DCtoDC converter in the CAR may charge not in a proper way. Besides that, the Optima battery has a very short warranty, only 2 years.

Don't put non-AGM batteries in the Trunk. It is very close to the HV battery and inside the cabin. Any accident from the rear collision could be fatal to the passenger on the back and your HV battery. The flooded/non-AGM battery also has different charging properties.

 

The Gen4 (which is what this thread is) DOESN'T have a battery in the Boot. And TOYOTA's specification for Gen 4 battery is NOT AGM - but Flooded.

 

Actual Toyota battery is less than $200 MSRP, I recently replaced mine at dealer for $165, pushed discounts based on coupons and Interstate Battery having one for $155, dealer came down to $165, good enough for me for genuine Toyota battery. which is AGM I believe, but overpriced if dealer charged $700 to replace, dealer took big advantage of their customer, run away from a dealer like that.

 

Maybe more succinctly: gen 4 battery's at the front of the car, under the hood (aka "bonnet"?), traditional location.

 

Yep - that too.

 

Yes, we all know the 4th gen do not have battery in the trunk, that's why we can use regular Walmart Battery. We still have AGM in 2.0L corolla hybrid sold in EU and they still use AGM battery. Unfortunately, with a new supplier VARTA instead of Yuasa, it has quality issues and died prematurely.

 

That's what I talk about. Yes, we can get better deal by shop around even Online in Toyota dealership.

You can go with any cheapest brands and often Walmart has exact same battery as other stores with the longest warranty. But not with AGM battery. Only Yuasa/Dealer parts are good

 

Your biased opinion.
There is NO good reason to think that other companies can't also produce a good AGM battery.
In fact, a lot of them probably are made in the same factory.

 

My 2020 doesn’t have an AGM battery either.

 

No but the replacement CAN be.
Which is true of any car.
They are arguably better.

 

Oh heck, how so? They last longer?

 

I think we've covered this before.
They don't "gas" and lose water.
They don't leak if turned sideways or upside down.
They don't suffer the ill effects of sulfation nearly as quickly.
And yes, then tend to last longer.
