Actually, $360 for the battery, $18 for the terminals, and $22 for fireproof foam.

Old battery 37 lb 1.8 oz
New Li-ion battery with terminals 4 lb 13.4 oz

I needed a new battery so I thought I'd give this a shot. So far so good. Always fires right up and I've even let the car sit for 3-4 days. I've had it "prop" installed for about 1.5 weeks. Today, I finished up the final install.

Works great. My only concern is longevity. Fingers crossed for at least 3 years.

Did the original old down bracket work or is the new battery narrower?

You need to detail under the hood.

The new battery is narrower in width and length, and shorter in height. I fit the new battery in the OEM full battery sized fireproof blanket/wrap by adding fire proof foam to the bottom and sides of the battery, between the new battery and the OEM blanket. As a result, the new battery sits at the same height the old battery did and the OEM bracket works.

Curious, what do you expect 32 less pounds to do for you?
My 2017 still has the factory battery in it which I expect to change soon. I plan on a Optima #35 AGM Red Top for about $300 but am open to options.

You're asking why someone would perform weight reduction on their car?

If you have deep pockets, you could get a full size Li-ion battery but expect to spend $8 - 900.

He's just preparing for the weight he is going to gain since Golden Corral is open again.

If anyone wants any foam, I have more than I care to store. I didn't even use a full 2 out of 12. What was I thinking buying a 12 pack, lol.

Weight reduction is a thing where the sum is the greater than the parts. You can't really shave a couple hundred pounds by making 1 change to a car, but you can make 20 changes that each save 10 lbs.

Of course I understand the benefits of weight reduction I just didn’t know you were into shaving tenths!

I had thought about a lithium battery in my previous vehicle (was going to run a dual setup, both lithium)...Seemed like there was something in a regular car charging system that wasn't ideal. Believe it was the alternator with regard to voltage or always on max charge, or something like that. Imagine the car (lithium) battery has this in mind, so perhaps it has some built-in circuitry or whatever. Heard of people doing this and like I said, looked into it myself, just there was something about it that needed to be addressed. You may have already looked into this, so just mentioning in case not.

Very cool. Have you measured 0-60 or 1/4 mile times?

No, but I want to so badly. No tracks near me but I do have a Dragy. I just need to find a good roadway free of slopes, traffic, houses, businesses, cops.

0-60 times with the Dragy are easy to do, I’ve pulled over on the highway to launch. Finding the near flat run is difficult around here. 1/4 is much more difficult due to the high speed.
