New 12v Battery, Part #28800-21171

I'm getting a quote of $180 for part number 28800-21180. Is this the old part number and my dealership just didn't update?

 

If you can't do better than $180, I'd just buy Toyota Prius 12 Volt Auxiliary Battery with install kit for 2004 - 10 instead. (That's what I have and when I bought it, the OEM part # change and price increase stuff hadn't happened yet.)

 

I just bit the bullet and bought the Optima with install kit. Hopefully between hubby and myself, we can figure it out. How many hours does it take a car repair-challenged couple to get it done?

 

You get to tell us your experience and how long it takes you. You may find that it is not easy to replace the positive terminal battery connector which is required if you are going to install the Optima.

If you don't already have a decent set of metric sockets and open/box wrenches (as well as a 3/8" socket wrench and suitable extensions), I suggest you invest in those tools now, before the new battery arrives. You will need at minimum the 10, 12, and 14 mm sizes.

Don't try to do this job with cheap tools like Crescent adjustable wrenches. That will only lead to frustration.

It is easy to drop hardware into the fender area as you are trying to reinstall everything. You may find that a wand with a magnetic tip will help to retrieve a dropped screw. The screw that secures the traction battery vent to the fender is especially easy to drop into the area below the 12V battery.

Make sure that the battery mounting hardware is tight so that the battery cannot move around, and that the cable connections are secure. You'd be surprised to see the occasional post where it turns out the root cause of the OP's problem is a loose 12V battery connection. Good luck.

 

Thank you for the post, I started to order the Optima. I ended up on Amazon.com. I did not see the actual Prius version battery over there, but saw that ratings on some other models were slipping if you sort comments by date. So I am hesitating for guidance.

 

If you order it from another source, you'll still need Installation Kit for Optima battery in Prius because the terminals aren't the right size for the Prius' existing hardware.

 

Agreed about not using crescent wrenches. My advice at http://priuschat.com/forums/gen-ii-...id-seattle-area-installers-2.html#post1264180 might help in terms of extension length and possibly needing a longer ratchet handle.

If you can work in front an auto parts shop or tool retailer, that might help, in case you need to borrow or buy something. My local O'Reilly has a box full of random tools that you can borrow. I was able to borrow the much needed longer ratchet handle instead of having to buy one. The one that came w/my socket set was too short to get enough leverage.

 

Thanks, Patrick. We will be armed and ready when the yellow-top arrives!

 

I bought the Optima from Amazon and then went to my local auto parts store and purchased two of these style terminals (Could just get the terminals from Amazon at the same time. Search for "top post battery terminal").

The positive cable bolted straight to it. The negative side I bent flat and used the two square washers and the bolt supplied with the terminal to bolt it to the new terminal. Total cost was $151 shipped for the battery and $5.01 for the battery terminals. I had to cut the positive cover as shown in the excellent install guides provided by other forum members. For the breather fitting I found it is just a standard vacuum fitting and pulled one from my tool box. The total installation time was 34 minutes from start to finish, including putting tools away. Part of that time was spent plugging a hole left open by the dealer when they repaired the rear of vehicle from accident damage.

BTW I live in California so buying anything from Elearnaid requires I pay sales tax.

 

You can also get a short cable + terminal for the negative from Walmart for a few bucks.

 

Just a note that if you get the Optima YTS 2.7J (8070-176) rather the YTS 2.7 (8071-176), it has the Japanese terminals rather than the SAE ones and you don't need the terminal adapter.

Optima don't appear to officially sell this in North America, which is bizarre, but you might be able to find one somewhere.

 

If Toyota are serious about keeping the new part number costing $284 msrp, then Optima may be persuaded to offer it in North America. We can hope, and keep asking them...

 

It's $284 in trademotion for this part number. Toyota is re-vending these from Yuasa (or is it Panasonic? can't remember), and perhaps the reason for the new part number at a higher price for the same product is so that they aren't taking a loss due to the weak dollar vs. yen? Time will tell.

 

trademotion is basically the server side for all of the online parts counters at car dealerships, not just Toyota. Usually, different parts counters show the same MSRP for an item but then have a different price. All the ones that I have checked still show $138.70 MSRP for the old part number, and $284.14 for the new. I do not know man, I think it would have happened already.

These folks sell the new battery for 116 + 10% shipping = 127. It seems to be most reasonable price for a toyota battery shipped to the house. I like optima battery but toyota battery is great for someone who just wants plug and play. Plus optima is not cheap. It is good if you don't want to mess with the battery for next ten years.

116 for new part number at "Toyota Parts" | "Toyota Accessories" | 1stToyotaParts.com . They want ten percent shipping on most items. 11.60 shipping and no tax is a fair price. I still don.t understand why people only talk about optima as the only other replacement. Optima is a d51(battery size) and why can't we just buy a d51 costco battery for $57.99(interstate, sears, etc). Costco battery should last good 5 to 8 years depending on the climate.

 

You can get 71 for 128 ish shipped to your house. No tax for california. check it out "Toyota Parts" | "Toyota Accessories" | 1stToyotaParts.com

This is also a toyota dealership so your warranty should be good.

 

Success! I did it in bits and pieces. I think overall the actual time involved in the installation was about an hour. I had a couple of small bumps along the way. First of all, I snipped the end off of the vent tubing because I thought the connector would fit better. Wrong. So we had to buy a new end piece for the tubing. $2.49 Then somehow I missed the fact that the negative post on the new Optima is a lot bigger than the negative post on the OEM. So then we had to make a run to the car parts store and an incredible employee helped us put a new connector on the old wire for us. $4

The instructions from Educaid were wonderful and easy to follow. It was a smooth install even for a non-car techie like me. And the best of all... my MPG has already jumped significantly. Happiness all around.

Thanks for all the tips and support. I am so proud of myself!
