Hard to tell if it’s worth it, but it works.

The battery is very lightweight. Installation took me about 1 hour ( you’ll need YouTube and some tools, folks). I really won’t know if it lasts longer until maybe 227 so stay tuned!

Not for Older Tesla's?

I paid Tesla to come out and open my model S (if the battery dies, nothing will open. You must remove covers in the two front wheel wells to pull on two orange handles to open the frunk). When I offered the Lithium 12 V Battery to the repair person, he said that those only go in the newer cars (mine is a 2016). He say he installed a led acid battery.
I had to argue a little with Teslarati, but since I hadn't even opened the box, they took the Lithium battery back. I just had to pay shipping.
Does anyone know what part of what I was told is true?

Fantastic product

This battery is super light and easy to install. Everything in my 2014 model S works better and faster. Very happy this lithium battery.
