lightest in physical weight? Like you're trying to find the one that weighs the least?
oem replacements:
duralast: 51R-DL = 26.1lbs
You could go with a honda odyssey battery - like 14lbs. Not 100% what you're looking to do?

Braille makes pretty light batteries.
No-Weight 11.5lbs.

No-Weight 15lbs.

Carbon Fiber 11.5lbs.

Carbon Fiber 15lbs.

I would recommend the 11.5lbs for track use (no a/c, radio, or other electrical system being used) and the 15lbs for daily use.

I've got a Shorai lithium battery in my motorcycle, it was about 1/3 the weight of a standard gel cell. I only put it in this year, but the manufacturer says they are supposed to last longer than typical batteries in that application. That said the last two automotive batteries I had to replace were more than 7 years old so that may not hold true in cars people use every day. I haven't seen any lithium battery applications for cars yet, but I'm guessing they aren't cheap.

I had the odyssey batt in the 8th for a year or so. Worked just like a reg batt and weighed 13lbs or so. Only had one issue when I left the car sitting for 2 weeks. Had to get it jumped....worked just fine afterward.

I did see a review of a dude who compared a Shorai Battery with a Ballistic Evo2 and a standard Lead Acid. I guess it's okay for bikes to use lithium ion batteries because they don't use as much electrical power as automobiles.
Just curious. Is this just for overall weight reduction, or is there another objective here? What is your goal and what are you gaining vs. cost of replacing (what I assume to be) a good battery?

If you do that often I'd look at a trickle charger.

I did buy one. I noticed I need to charge it once every 5 or 6 days. I have a work truck so The car could sit in the garage for up to 2 weeks at a time.. As long as I keep charging the battery it should be fine I bet. Totally worth it though I love the tiny battery.. I bought the one with wrapped carbon fiber..

It's mainly for weight reduction so the car's center of mass would be closer to the ground. It probably makes a significant change, but not by much.

So you're not leaving the charger on the car while it's parked?

I know people who keep them on cars for months at a time (winter months year in/out for 20+yrs without issue). Yet, I just saw this article which claims you should only do it with float chargers.

I actually used two of this Ballistic battery for my School's robotic boat project. Each weighs at around 2.4lbs. I wonder if they work well with cars. I know they are great with motorcycles. It just needs to be kept in a tightly sealed case since it is a lithium battery.
