First battery replacement for me and the car has never ever been on a battery tender. I am going with a Diehard Platinum AGM battery. Pick it up this afternoon. I had to order it this morning.
Taking off the plastic cowl was a piece of cake. My vette's battery is in the trunk. It is always on a tender.

The battery in my Grand Cherokee is under the pass front seat. :icon14:

This one is going in.

On the topic of batteries, I thought I would comment just because I tried a Lithium Ion battery this year. My experience so far has been exceptional, so I am quite excited about it, and I really was skeptical going into it.

I picked up an Anti-Gravity brand battery. They make one in a case that is direct replacement size for the GT-R (no need for custom brackets or hardware), which is already smaller than a Z battery to begin with. It was a 18.4 lb reduction from the standard GT-R battery, I imagine 20# maybe more reduction for the Z. I will definitely be getting another for the Z. It has crossed my mind to perhaps make a little batch of hold-downs to put this GT-R size version into the Z. I would love the extra space in the battery compartment personally.

The car cranks as hard if not harder. The battery has an internal kill switch that allegedly detects when the battery is getting low, if there is some sort of drain, and shuts itself off leaving enough juice to crank the car a few times. There is a button on top of the battery to reset that kill switch, and there are also some key fobs that do it remotely included with the battery. I can only assume this feature works correctly, as due to the phone app, I cant see how I would ever find myself in a situation to need it.

Which brings me to this device, which is not technically part of the battery, but part of the package I installed and I love this thing: https://antigravitybatteries.com/pro...acker-lithium/

Its a bluetooth transmitter for your battery. Add the free app to your phone. Any time you are within range of the car/battery, it syncs data and sends any appropriate notifications to your phone. So the app gives you a battery percent gauge just like your phone has for its own battery, and you can also set alert points of when to send a notification to your phone about battery percentages... Example, send an alert to the phone when battery gets down to 40% or etc. Then you know you better get out there and put on the trickle charger.

So having this tracker, and assuming the car is parked inside the home garage within bluetooth range of your phone, I really dont see how you could ever have a surprise dead battery.

PS this battery tracker device from Anti-Gravity is cheap, like under $40, and they also offer it for lead/acid batteries (different part number). I have been meaning to go and order a couple more for the truck and harley. I dont personally know enough about batteries to know if something like this can be as precise/accurate on a lead acid battery or not? But I am going to try it.

Sorry for the long sales pitch post, I just really dig this new battery situation I have going on and think everyone else would be happy with it. Now it just has to keep working a few years and not burn my house down.

Ouch!!!!

That sure has got me thinking. Phunk, you are a bad influence. LOL

I got the package T1 Race sells for the GTR. Its less than that and includes all the extras: https://www.t1racedevelopment.com/pr...y-r35-package/

I can probably get that package to you even a little less than that if you want one. Let me know. If I start selling them, I would go ahead and toss the one I have in my Z real quick so I can draw up a simple tie down. I am sure the stock tie-down will hold it anyway, just would be nice to have a proper fit one.

WOW, that is a whole lot better price. Damn you...LMAO!!!!

I mean the total isnt much less but it includes all the extra you need at least! Probably be over a grand for the same package direct from the manufacturer!

It seemed expensive to me until I got all the stuff in that package, then I literally messaged the owner of the company and said this is actually a whole lot of cool **** for the money! Its just mind blowing when you pick up the battery. Its value really just depends on its long term reliability. If it dies in a year, I will be pissed. If I get 4+ years out of it, I would do it again for sure. When you feel how light that thing is, you would punt your current battery out the front door if it wouldn't destroy your foot and ankle to.

Saw the Antigravity on Matt Moreman’s channel, it is neat. Actually not as expensive as something else I’ve seen....I think it’s Lithiumax out in Europe, they are all below 10 lbs :driving:

DM'd you on Instagram.

There is a CF case one called liteblox or something along those lines. I cant remember numbers but if I recall correctly it was 1500-2000$. For me personally, that is out of range for the weight savings over an anti-gravity. Especially in a car that has so many other places to save greater weight for that type of money. Plus, I still dont entirely trust these things to last more than a year or two yet.

I was looking at adding all the add on's too.

Yes yes yes that’s the one....yea the price on that one is nuts

Well, I am getting an Anitgravity Battery...

They are no longer made in the states.

Well, I done good. Nothing that can't be fixed with Darton MID sleeves installed.

I fixed my funny starts. It was actually the key fob battery. I just replaced it. Getting a new car battery anyway. It is only 8.6lbs. LOL

That’s not good

:iagree: :eek:

Head lift is a bitch. All that get's cut out anyway.

Looks like it's been eating away at the cylinder wall for a while. The area between the 2 flame cuts is being eroded away.

Probably because i ran the car from time to time because I needed to hear it run. It will all be over shortly.

TA DA!!!!!!

By the way, the deck of the block has not been finished. All Mazworx secrets are intact.

New battery I was looking at was 40.4lbs. Antigravity battery is 8.6lb.

Spool, you know when you post the flickr pics on the forum and the link is busted, it posts your full name instead?

Freaking Flickr crap. Fixed it.

Maybe I should be living in a van down by the river.

Sell you a motorhome so that you can do it in style. :tup:

How am I gonna do that living off of Guberment Cheese.

Take a loan out. Buy the motorhome. Then go off grid and not make the payments.

Jealous :yum:

I have a 3D printed battery tray for my red top opt. Bsttery

Mine battry is going in the rear :ugh2:

Sounds about right for you. You like to stick lots of stuff in your rear. :rofl2:

I bought the tray as well. But the current AGM in the car will never die, be a while before I get to install it, just like other parts sitting in my garage....

I’m the king of hoarding parts
