Stock RS battery is 95Ah. Braille i48CE/CX rated at 75 PbEq/LAH (lead-acid equivalent) and i48CS is 150. Best to discuss best option with Gary.

It was an option (see catalog image) but Porsche pulled them from the orders of later cars. Mine had the battery pulled with no explanation but I believe it related to supply.

I believe Porsche pulled them because of a liability issue. If they drain out and do not have a safety feature your out $2500. Plus, in Cold weather regions you should put them on a trickle because not all these Lithuum batteries are built for extreme cold weather

​​​​​​​Braille makes the best and quite durable for cold weather

I bought my GT3 new and it came with the standard battery installed and the optional lithium battery in a separate box.

Are you satisfied with your decision and why?

GiuseppeM

I'm not the person that build it, not sure if it was the dealer, I don't know if there are any advantages other than weight but I wouldn't have paid extra for the battery. When I bought the car the lithium battery was in a box in the frunk.

^ Just weight which is a good amount. Nothing else i would be convinced to believe. Longevity is also a plus.

Thank you gentlemen for the info.

I have it in my RS. Just leave on charger when not in use.

How long do you think it would last before it dies?

I got it in my car, but my parking spot is no where near a power point. I've got the charger though...just no real way of charging if I leave the car for a long time.

Same here. Sitting in a box in the garage. I hear its mainly for track use. Was also informed if i dont plug in the car, the battery would die. What are you guys thoughts?

GiuseppeM

I'd like to know this as well, the standard battery has been pretty solid and I never had to put it on a charger, remember the Lithium batteries require a different charger (looks similar but has the LiIon logo)

This is from 2012 but talks about Porsche GT3's Lithium batteries:

I have a LWB (in a box), but dealer recommended not fitting it over the winter as it can be temperamental in cold weather.

thank you!
