12 Volt Lithium Battery...Possible ?

Being my first Prius I assumed it had a standard size 12 volt battery, apparently it doesn't.

My brief look at a few posts tells me it's a very small battery, just wondering how small, is it the size of a motorcycle battery ?

If it is...can it be replaced with a lithium equivalent ?
This is an excellent question. I have had to replace my 12v AGM battery too many times and have to charge it frequently because I apparently don't drive enough. I couldn't help but wonder if a lithium battery wouldn't be more forgiving of the deep disharges that continue to happen even though I charge a couple of times a month. Somebody said lead acid was forgiving of deep discharge. That has not been my experience and not what I have heard in doing my homework over the years. Of course, maybe the better solution is to have switch and just switch OFF the battery when not using for a while. What can you lose other than your clock setting? But still the lead acid battery doesn't hold the charge as well as lithium and does better when stored at a higher rate of charge than lithium, correct?

I just replaced my battery yesterday with one from the local parts store here in Vancouver. It is ACDelco brand part number ACDB24R. It was $164 + tax with my discount. Original quote was $210. My car is a 2010, but I would have thought the battery would last longer. My friend gave me a ride to pick up the battery and his 2001 Civic is still on the original battery.

I have used that same battery, and it just doesn't seem to hold the charge well. Plus if you leave the trunk light on or something it will fully discharge and doesn't seem to hold the charge too well after that either. Not very forgiving.
