Lithium battery fitted -12kg
Discussion
That's good to hear Liam.
@bcr5784 Porsche quote 'about a thousand' for a replacement LiFePo' for a Taycan. Mine is just about to have its third in two years (all under warranty) due to a software glitch (don't ask..!). Speaking from experience, you don't want to be stuck with an EV with a completely dead 12v battery..
A replacement lead acid will probably be c.£120? The Antigravity battery is c.£790 for a 24Ah model but I'm ordering an Optimate charger and quick connect lead as well as a remote monitor. I'm fortunate in that my Alpine is garaged and therefore connecting it to a trickle charger is a cinch. These batteries do have a useful 'jump start' feature that will give you 2-3 attempts at cranking the engine if the battery goes into self protect mode. Unlike lead acid batteries, the LiFePo battery will switch off if the charge drops below 11v.
The guy at Antigravity was very interested in the A110 application, and very helpful too.
Something that will be an issue is the stop/start function, as explained by Liam22 and a110au previously, but I'm willing to live with that in exchange for shedding 12kg.
On the plus side, £65-70 for each kilo saved is pretty compelling, esp as it is relatively high up in the car.

As I have the slightly porkier Legende GT with comfort seats I'm keen to find some weight saving.
Inspired by Justin's very detailed thread on the subject https://www.pistonheads.com/gassing/topic.asp?t=20...
I decided to buy a reassuringly expensive Antigravity battery. They have a drop-in replacement in "group 47" (aka type 027) form factor. 24Ah, 30Ah and 40Ah options are available. I went for the lightest (ahem, cheapest) 24Ah option at 3.9kg. The OE battery is 16.0kg according to my bathroom scales.
Although it has regular battery posts, they are also tapped at M8 and supplied with stainless steel bolts. I liked this option, although I had to open up the holes on the positive cable ends from 6mm to 8mm. It's also a slight faff with the captive nut on the negative cable, but no big deal.
With the foam/foil insulation box reinstated, it looks very much like the OE setup.
I also picked up the same battery monitor as Justin, so I can keep an eye on the voltage and temperature from my phone. I originally attached this to the centre of the front face of the battery, but it fouled the frunk tray just enough so that it wouldn't go back in properly. Now relocated to the bottom left of the front face.
With the OE battery condition monitor deleted, the "check stop/start" message needs to be cleared with a press of the left stalk on startup. Also, the "disable stop/start" button on the centre console has changed from white to red. No other ill effects.
After installation, I drove it once and then parked it for a week.
Cranking voltage drops to 12.0V [good]
After the engine bay fans finished, battery voltage was 13.38V [expected a bigger drop]
A week later, battery voltage was 13.33V [still >90% state of charge]
So this looks pretty good, and glad that I didn't spec a larger capacity. I was also impressed that the car remembered the time - I was expecting to reset the clock.
The nice thing about the Antigravity is that it will disconnect itself if the voltage drops too low. There is a button on top of the battery, and 2 remote keyfob buttons that will restore power with enough charge to start the car.
I have an Anti Gravity H5 AH40 at home and was wondering if it would fit in my A110 so glad it does, just a couple of questions please:Inspired by Justin's very detailed thread on the subject https://www.pistonheads.com/gassing/topic.asp?t=20...

1. Does the anti gravity clamp/secure to stock mount?
2. Why did you delete the battery monitor, is that necessary?
Thank you.

where did he say he removed the battery monitor? I scrolled back but didn't see that at first glance.1. Does the anti gravity clamp/secure to stock mount?

It doesn't leech much if any power from the battery while connected and is invaluable IMO. I can walk near my garage and check on the app the SOC without touching or activating the car in any way.
I think Gibbo is referring to the OE 'battery condition sensor". The reason for removing it was already described in detail https://www.pistonheads.com/gassing/topic.asp?t=20...
As for the clamp. I went for the Antigravity H5 form factor so that I could reuse the OE clamp. It's a drop-in replacement.
