Porsche OEM Lithium Ion Battery
Looks like Porsche has jumped into the Lithium Ion Battery game, has anyone bought this. There is a vendor on here who sells one for 1K and I will bet in time these will be a really affordable upgrade.

and oddly Suncoast has this for $4100 ??? I guess the $1700 is an option not a purchase price ?

anti gravity has one for $700, RS 30, but you have to buy the battery holder too for another $200
still a lot less than the Porsche one

@11.5lbs I'll just ziptie the thing down and save two hundred dollars LOL not a bad option IMO.

If you go the lithium battery route, the weight savings are close to what the T offers and it lowers Center cengravity a little. But be prepared to put the battery tender on it anytime it sits for a day. I'd probably put mine on it every night in the garage. The Li Battery A-Hr rating is 58% less vs the AGM.
But still, if my 991 needed a new battery without warranty coverage, I'd be tempted to go lithium, as the additional cost of going to the Zero Gravity is "only" $700. I'd have spent the added $200 cost on a new AGM battery anyway.

Agree. I would not want to use a Li battery if not storing, and having to cold start in Winter weather. But here's a thought - you could go lithium and swap back and forth in the Fall & Spring. The AGM battery on the shelf would need a maintainer, but it's my understanding that Li batteries do not, if stored while charged.

Plus, lets not forget that our modern Porsche 991s have regenerative braking. They prefer not to charge the battery when accelerating or cruising, but are programmed to charge the battery when engine braking (forget that stupid Greenie eco coasting option!). So there is no assurance your 991 battery will be fully charged when you park it in your garage when arriving home. If you only have a 30 A-Hr Li battery in there it might not have enough charge to sit for 6 days of current drain while parked from Sunday to Saturday, and still have enough charge to be able to start the car when you are ready to rumble.
And Li battery life is generally not as good if often stored at relatively low charge. They seem to like at least 70% charge during storage, for longevity. So that is another consideration.

A Li battery should b fine for a daily driver. But cold winter weather starts are more difficult for a battery. Do you have severely cold winter weather? If you only drive weekly, a Li battery has limits for storage without a battery maintainer. I don't know the load when a 991 is garaged, but simple math for example says at a 200 mA load, a Li battery will discharge about 50% in 3 days. So id use a maintainer unless driving it the next day. Without keyless Go, the current drain when parked should b less. Who knows? You might get away with 5-6 days in the garage without a maintainer if you don't have severe cold spells A start in cold weather requires more from the battery. The reason i am sharing a battery mainteance is a good idea is based on the small capacity of these Li batteries, the relatively high drain these modern Porsches have when parked, and a friend who runs a Porsche race shop who says a battery maintenence is going to be required for much of the time a 991 sits in a garage.

I'll do some more research, but most of what I've read so far indicates lithium batteries are less than ideal in sub-freezing temps. But it's easy enough to swap them out when I swap the tires, so I'd probably do that, if I wind up getting one.

You ride in 35F? Damn. I'd have to wear so much gear I'd look like I'm setting out to climb Everest to do that.

Only concern is tire grip, so no sudden acceleration and have to be careful. Bike has traction and Abs and usually keep it in rain mode in the cold. Just have to avoid any icy patches. As long as road is dry its all good.
when not riding I keep it plugged in to optimate, 4 years with no issues with the lithium battery. I ride a HP4, all the electronic aids are a big help.
for the car I swap to winter tires.
