Anyone tried an AGM battery alternative? Any info?

[frj322]

Good morning everyone!
After 4 years the factory battery in my 2018 F3S has faded into the sunset.
Yes, I’ve load tested it and it’s finished. After many years as a Chevrolet dealership tech I’m not 100% convinced I want to go back with an AGM. Had many die in Corvettes sooner than they should and always with no warning.
A thread search has revealed many here are fans in OEM and normally I would be too but I wonder if anyone has tried an alternative, where did you get it, and what was your experience?
As always, thanks for any information you are able to offer.

At the suggestion of another member here I went with this option a few months back and am very pleased that I did. Just grabbed the attached screenshot and I see it has had a price increase.

I have the "restart" model in all my bikes. I'll never go back.

My factory battery lasted 9 years. Used a maintainer in the winter months.

This is the one I am using. I am very happy with it. They are so light you would think the case to be empty.

They are expensive, but what I like about Lithium is the extremely low discharge rate. For some reason, AGM batteries, in at least some Spyders, seem to discharge at a high rate. Requiring a tender to keep them up. I don't seem to need a tender on this battery. Otherwise, I've also had very good luck with the Yuasa battery.

Replaced the battery in my '85 Honda Gold Wing Limited Edition FI model with a LifePo4 lithium ion battery from Alberta Lithium. My 2014 Spyder RTL uses the same AGM battery as my Gold Wing. Cost was $30.00 more than another AGM. Total in was $210.00 to the door. Need a different charger.

These are very light and work well.

Thanks for the replies everyone. Decided to go back with OEM.

Is this the one you use "Antigravity AT12BS-RS"? What has been your experience with useful life, starting operation in heat or cold, or other pros and cons?
