12V battery group size

Check out this battery and see what you think, it is out of a Chevy Spark.

It is out of stock. Plus with the core fee, may not be too much of a difference from the dealership price. I think I may just overpay a bit and go get one from the dealer, to avoid back and forths with it not fitting and whatnot. Sounds like no one has actually tried fitting an aftermarket battery on yet, cars are still too new. Thank you though.

 

You are a pioneer.

The battery I recommended is an AGM and they cost more than conventional batteries like the ones that come in the Gen 4 Prius.

 

I think you're right - no one has reported back after changing a 12v battery.

Personally, I'd go with original. If it was a "normal" hatchback or SUV, you could second-guess, but PRIUS battery has a unique/different purpose than batteries in 95% of cars on the road.

 

That's a good ploy till the 4th gen has been around a bit longer, and the aftermarket producers see more demand.

 

With this world economy and cars being shipped all over the world you would think they would come up with an international battery size program and eliminate some of these oddball size batteries..

 

You mean International cooperation? Wouldn't this come sometime after world peace?

 

The biggest cause of troubles in the world today, battery size

 

... and not just batteries.

Read through this thread. Did a tiny bit of research.

I believe the Prius Prime's battery dimensions to be 207 mm × 175 mm × 190 mm and weigh 12.7 kg.

Looking at this list, we can see that the battery type 26R is similar in dimensions and may be a swappable candidate.

If that is the case, this opens up quite a few options if people are interested. For instance,

PC1200T | ODYSSEY Batteries

Pulse (5-second) Hot Cranking Amps (PHCA) 1200
Cold Cranking Amps (CCA) 540
20Hr Nominal Capacity (Ah) 42
Reserve Capacity Minutes 78
Dimensions L x W x H (in) 7.87x6.66x6.80
Metric Dimensions L x W x H (mm) 199.9x1691x172.7
Weight (lbs) 38.2
Weight (kg) 17.4

This battery has a shorter length, is wider, a shorter height, and weighs 5kg more.

Here is a pic of my 2017 Prius Prime.



And the battery.



I don't know how much of (if any) of an upgrade it'd actually be.

 

This is actually a GEN 4 PRIUS thread - are the batteries similar? Has your PRIME battery failed?

 

It would probably work in a pinch, but I still think an aftermarket LN1 battery, like the Duralast H4-DL I mentioned in post #68, in stock at AutoZone stores for $130 plus core charge ($18) and sales tax, would be a better choice. Not only are the dimensions the same as the original, it’s also more likely to have terminal posts that fit the existing mounting hardware for the current sensor (–) and fusible link block assembly (+).

Yes. The same kind of auxiliary battery (Toyota manufacturing part numbers 28800-37130 or 28800-37140; service part number 00544-H4052-470) is used on the Prius and Prius Prime.

 

Since the Prime is based off the Gen 4, it appears to use the same battery.

I have posted some Gen 4 experiences in Prime forums that have helped people. I just make it clear that I am talking about a different, but similar car much like our Prime owner here did.

 

Found this higher performance equivalent on Ebay UK, a Yuasa YB5012.

Here's a video on the gen 4 12v charging system

I think I will leave my battery alone until after the car is out of warranty. Maybe opening it up and adding distilled water would void the warranty or let the dealer do it. When I bought my car it was two years old already and was on the showroom floor with a dead battery. It will be interesting to see how long it lasts.

 

Yesterday my wifes battery in her 2016 went flat dead for the 2nd time in 2 weeks, she has 84k miles on the car and does home healthcare so her being stranded is not an option. After some research and finding a few ideas here I took the battery to AZ and grabbed the 26r off the shelf. It is basically the same size other than being about 1/2 inch taller and 90 minutes of reserve instead of 45. The 26R fits perfectly without any modification.

 

This is the first 12 V battery failure I have noticed on the forum, I see you live in a hot climate.

 

That and she drives a lot, and sits and idles while doing paperwork. We have had some crazy temperature swings in the last 4 weeks. A few weeks ago she went to her car and it was dead, I checked the battery with the volt meter and the battery was reading 7.6v. I put the genius charger on it and it recovered to 12.7. Now it went from fine one day to flat the next, apparently the battery is failing to hold an appropriate charge level. The factory battery was not an AGM, it was a standard lead acid yuasa battery.
