12 volt Lithium Battery vs. 12 volt Lead Acid Battery

[bc1]

Hello guys. Thought I'd ask here since we have some battery experts in house. Looks like the 12 volt auxiliary battery on my 2013 Prius has crapped out with the low temperatures. In looking for a replacement I see where they sell what they call a Lithium 12 volt battery. Just wondering what anyone thought of these?

I don't know how old my battery is but don't remember replacing it in the last 5 or 6 years. I've bot the Yellow top Optima for our prior 2008 Prius one time. I'd probably have to order the Lithium online unless someone locally has it but its numbers are a lot better. On the other hand I plan to sell the Prius as soon as I put new brakes on it and clean it up whenever it warms up and I have time which has been the plan for over 3 months now. Thanks.

In that case, buy the cheapest battery that will work. No point in putting in an expensive battery into a vehicle you are selling in a few months.

Lithium 12 volt batteries are great, very light and compact compared to any variety of lead acid battery. But they’re an investment. I use Dakota Lithium batteries for boats and back-up power and love them. But they’re a premium product for the time being.

Are there any 12 volt lithium equivalents that anyone has used in the lightning?

There are threads such as the following:

Some folks like 'em, others don't.

I personally prefer to keep the AGM battery rather than spending a bunch on something more expensive and potentially troublesome to lighten the vehicle by around half a percent. However, AGMs aren't without their problems too, and for some uses lithium 12V probably makes sense.

I wonder if anyone has tried possible NiMH options?
