Lightweight Batteries, Comprehensive Information to help your decision Options

[Tigawoods]

I have this medical condition called laziness.

No, I just wanted to put the battery in so I could get the car started asap, didnt want to make time to fool around with relocating.
This battery would fit perfectly in the jack stand compartment too

You would also need a battery designed to be vented for passenger compartments. Your not supposed to place a standard battery where the passengers can breath the fumes.

yea i've read about this as well. but thats why you open the windows from time to time. thats what members told me on a post here regarding lightweight batteries.

Well as I expected: I had the car running at 14.5 volts one weekend and came back the following weekend and checked the battery and it had dropped to 7.4 volts, and needed a jump to start the car.

So the car would need to be started periodically throughout the week to keep up the charge on the battery

Looking over this again to edit in the wake of a few questions I have been asked and my battery re-location.

My Braille2015 15lb is still kicking!

I have a AntiGravity Battery. Its about 3-4lbs. Been about 3 years. No issues so far.
I'll look for the part number tomorrow.

I've been running a Antigravity AG1601 all last year and will be again next year, I keep it floated at 13.5 volts with a max charge rate of 500ma, I leave it connected so I can do stuff on the car over the winter where I need power sometimes. It won't run the car long key on/engine off without a charger but it starts it very well even in very cold temps after sitting out all day. Last year I had it out all day parked in some temps in the 20's and it started it with very little hesitation. If it'll start a 1800 CC engine with 11.5:1 compression in those conditions it'll start a 7A or a 5S no problems too. Caveat is it needs to be floated if not being driven for more than 4 days otherwise the normal draw of the car pulls the battery below healthy voltage levels.

A little pricey but supposed to be really good batteries. I didn't relocate it but I'm thinking of how to mount it more cleanly while still easy to access to float it.

Dang bro. Do you even race. Thats lotsa money. Seems pointless to remount a 4lb battery. The suspension wont be able to notice the difference. Unless you have a full out racecar

One more to add. Tigawoods.

Duracell Ultra SLIU1RT

-AGM Internal design
-CCA 320A

I was just curious, not having 35lbs hanging over the front axle does feel a little different. I also was storing the car over winter in an unheated barn so I wanted something I could just unhook and walk away from instead of having it on a tender all winter, but got a house now so...whatever I got the battery I'm gonna use it!

Cool info!
Ill add them to the list.
Ive never heard of that brand before, but then again I am missing a good handful of batteries on the list.
