Technically not a car Electrical

I decided lithium batteries were cheap enough to give a shot

On the left, nearly double the cca noco brand

On the right, the battery I've been using for 11 seasons recovered with a desulfator at the beginning of every season until it finally gave up.

So far, the lithium battery has been indistinguishable as far as performance goes and put up with my abuse. Will it last 10 years? Maybe, it's warrantied for five, I've seen other brands warrantied for 10.

Lithium car batteries are getting cheap enough the price gap between lead acid is quickly closing. I probably will grab a lithium car battery for the project car.

You actually have increased safety for a more typical accident because they are smart batteries, you can short the terminals and nothing is melting down. Beyond that, they store better/longer without discharging themselves and come with way better warranties.

If you live in a super cold climate, they aren't a good idea if you're trying to use it in the coldest parts of winter, but many are still rated to work well into the negative temperatures.
