LifePO4 12V Drop-in(retail); Anyone actually tried?

After turning on the "Ready" mode, the 12V battery was disconnected and replaced with another one.
This saves the settings of the various systems.

 

Yup, I have one installed. No problems as the battery accepts the 13 - 15 V range specification of the charging system...

EDIT- Got one off eBay from a Chinese seller back in Oct 2018, so going on 6 years. I am planning on updating the thread next year, 1 year, 2 years, 4 years would be next year. After that I'll see if it lasts another 8 years before my next bump...

Which supplier? Are they still selling the battery?

 

Thankfully eBay still has record of the sale. Just find the cheapest 46B25R LiFePO4 IMHO.

But the seller I bought this specific battery from is 2014littleflower2014 .

I had trouble because it had mounting lip on the bottom which I explained to them as "edge". (Their English wasn't good).

My son went to do research at the NIH in Bethesda, MD. The car sat for 2 months with little to no use. I just needed to jump it with a NOCO, they charge so fast....

Here's one, doesn't have the backup start function but if you have it in the trunk not sure need it...

Be sure you verify it has the skinny/thin JIS terminals. (I believe they come with adapters. I bought a similar 46B24L for my son's Honda Clarity not very long ago. I'll check in the morning because his needs the SAE terminals).

@Onlooker You purchased a deep cycle LiFePO4 battery. The eBay sellers do sell those also but they don't like to sell them for automotive starting applications. Whenever I inquire about one, (they are usually cheaper than the starting type), they always sell me a starting type, which have "capacitors" of some sort to support cranking a starter. If you buy a smaller size battery such as the 46B24R/L then they ask if you have a larger engine size than 2.0L then add an extra capacitor for about $10-$20. For my son's Clarity it is a 1.5 L engine so I did not purchase that option. (I believe it doesn't use the 12 V to crank the engine similar to the Prius).

For the wife's Panamera it takes a huge H8 or Group 49 if I recall correctly. I tried to purchase a deep cycle battery because the CCA/CA was substantially larger than the AGM already but they still sold/sent me a starter type. I'm not going to argue over 10% more cost at $6xx price range as long as it works, which it has. For that car I was replacing AGMs approximately every two years. Now I barely remember the size...

I hope it works out for you and thank you for sharing your testing. I never went that far just saw the matching specs in the little booklet that came with my first one, and moved on with the install. I think all the eBay sellers source them from the same manufacturer or something. I do not believe I have purchased from the same seller twice, but one confessed to me they are all the same, (just different storefronts). I usually sort by price and pick the cheapest one, say with "dual battery" or "emergency start". That was January when I bought the 46B24L for the Clarity. It is in the engine bay so I got the function this time. (I'll try to take a picture as the sun is coming up)...

In comparison to the big one I got for the Porsche here's what a Braille equivalent would have cost me:

For the Prius v- I was very happy that they were answering my concerns over the weekend. (I honestly thought I would have to wait until Monday to get an answer about the bottom mount ledges). But they answered very quickly through the weekend. (That's an unforgettable experience). Eventually they asked me if I could make it work somehow. I went to Home Depot and got some washers, (maybe a longer bolt as well), and got to snug it down although not flat on the bottom.

I was told for smaller batteries they install JIS terminals and include adapters, (brass rings). I was promised that the next batch would not include "edges". Don't misunderstand that was originally the word I used to try to explain the issue of why it would not drop in fit.

They still do install JIS terminals AND include the ring adapters (as of late January my last purchase of one). Size shown is 46B24L (for a 2018 Honda Clarity PHEV).
