New Battery
Looking for some advice on replacing my old lead acid battery with a new anti-gravity battery. Are they worth the cost? I know there is a weight saving. And the battery will go into sleep mode if the voltage drops below a certain voltage.

Not worth the cost at all IMHO. The OEM AGM battery will last just about as long, be a quarter of the price, and have two or three times the capacity.
Your car has a BMS that will start cutting electrical systems if the voltage drops too low. Having a redundant one in the battery itself is pretty overkill IMHO. Having a battery inside your battery to jump your battery when your battery dies because you didn't plug it in and the measly 24AH capacity it has wasn't enough to last your three week trip out of town is just bordering on insanity.
If you aren't driving your car very often, but drive it often enough to have storage procedures be way too much of a hassle, just get a basic maintainer and plug it in when you aren't gonna drive it for a few weeks.
If it's a track car and reducing weight on the front half of the car is going to help you, and you can afford to drastically reduce your battery capacity since you aren't doing things like listening to the radio in a parking lot waiting for something, and you have a lot of money burning a hole in your pocket, then yeah. Get a lithium battery.

Agree. Stay AGM and get a CTEK if you can plug in. Or, do you have a particular use case in mind?

New Battery
My temporary residence has a carport with no Elec. So no way to keep the battery on charge. My work takes me out of town once a month for a week or more.

A couple of weeks should not be a problem whatsoever without trickle charger. I had mine sitting this winter for 3-4 weeks (in the garage) before I finally plugged it in as the cold and snowy conditions continued and my battery is 9 years old.

A week? I only have my battery on a battery maintainer when I am on vacation for more than a month and during the winter. The original Banner battery is going into its 9th year and I have never needed a boost or had starting issues. Why, is you battery dead after a week or two? If so, then you have high battery drain issues or an old battery with no capacity.

Only you can answer if it is worth it. For me? Nope. I don't need the front end of the car, or my wallet, to be any lighter than they already are.

unless your electrical system has problems, the parasitic drain is negligible and far, far lower than people would have you believe -- the same people, mind, that are trying to sell you a $1200 battery, or are trying to justify their purchase of a $1200 battery. a healthy car with a healthy battery will be fine after multiple months. 2-3 months is where I personally would consider doing some kind of storage ritual, such as unplugging the battery or hooking on a maintainer.

Im not sure if you have received a Quote on batteries lately, but I have and I have been quoted between $575 and $850 for my dealer to install with the cost of the battery itself being $385. At that price I will probably spring for the 60AH anti gravity at $850 and install my self with my Icarsoft..

Sure, I don't expect the usual 14+ years that I got out of my past batteries, but I am sure I still have a few years left in it. And when it goes, I'll get an East Penn or a quality battery like it.
