Lightweight battery

I got this one. 50% increase in capacity.

Antigravity T6/L2 Lithium Car Battery For Evora/Evora S/400/410/GT/Emira

A direct fit replacement lightweight battery for all 2009+ Evora's and 2022+ Emira! ONLY use a Lipo rated battery charger with these batteries or damage can occur. **We formerly offered the H6 group 48 size batteries for the Evora, it was reported that the H6 size was a snug/tight fit on some...

How do you like it? I will most likely do the JUBU 440, any issues with running this battery with aftermarket tune?

But according to the manual, it's a 70AH battery in the car now.

But according to the manual, it's a 70AH battery in the car now.

A 40AH lithium battery is roughly the same usable capacity as an 80AH lead acid/AGM battery, so it should be more than enough.

 

[Eagle7]

An amp hour (AH) just means how much power the battery can deliver in one hour before being completely drained. It would matter if you have accessories that are steadily drawing power, like an alarm system, etc., and are concerned how long the battery would be able to power them. Most of those types of things are drawing milliamps, which is thousandths of an amp. If you put your battery on a trickle charger each night, they're running off the charger anyways. If you're leaving your car for weeks without starting it or being on a trickle charger, you might have problems starting because there might not be enough amperage to start it.

The only real concern is having enough power to start the car. Once the engine is running, it's charging the battery anyways. The amp hours would determine how long you can go without starting it before you'd have a problem.

Ah thanks. but how able if you want to be able to store the car longer without using a trickle?

Yea but I thought part of the reason for this thread is not only the weight saving but to be able to store the car longer then 2 weeks without using a trickle.

Wouldn’t the restart capabilities in these batteries solve that issue?

Most people will use trickle charger when not in use, including myself.

So either the 40 or 60 would work for the EMIRA? It’s only a 3 lbs difference between the 2

Depends on what you've got using the power. If you have a dash/security camera for example, that's going to drain the battery faster than if you just have it parked without anything extra pulling power. Amp hour capacity is going to depend on what you're going to need and how long of an interval between when you start the car.

Yep. I bought the 40AH one.

Depend on your parking situation. The reason I'm caring for a new 718S is that my friend have to work overseas for the next few months but the secure parking for his highend apartment have no AC outlet near his space.

And I don't have a car yet to test mine. Probably six weeks to go.

Swapped in my Antigravity battery today with only 54 miles on the odometer. It was easier than expected, taking about 20 minutes. I also added their "battery tracker plus" bluetooth module that's fun/helpful for data nerds. It graphs your voltage, cranking amps, temp, GPS if you forget where you park your car, etc.

My Emira is now ~30lbs lighter and my wallet $880 lighter but I feel good knowing this will perform much more reliably than the OEM battery and probably last 10 years or more. Plus it has a reserve jump start capability which is huge if I forget to unplug my dash cam with parking mode running for a few days.

Very cool. FYI - For the little black plastic cover, you can trim ever so slightly to fit the pig tails of the tracker etc.

That’s excellent, but also extremely annoying as it doesn’t seem we can get these batteries in Australia.

If we could I’d order one tomorrow.

I guarantee there is an equivalent of some kind. This style of battery is super popular at the moment.

Took the time to get my LiOn Antigravity battery installed. You don't appreciate how light it is until you have to lift out the factory battery. Weighed both. The factory battery weighs 42 lbs. 6.8 oz. The 40Ah Antigravity weighs 13 lbs. 1 oz. About 29 1/2 lbs lighter.

Are these direct fit replacements? I could stand to lose 30 lbs on a diet, but this would be faster.

Yes. Uses the same mounting plate and clamp that the factory battery does. I got mine from GRP the vendor here. Fit's perfectly.

Is this the 40 or 60 you went with?
