And it is now the standard battery on the Turbo S. I guess Porsche didn't get the memo....
New lithium-ion lightweight starter battery
Lighter, more powerful, faster: the 911 Turbo S is equipped as standard with a lithium iron phosphate battery (LiFePO4). The new battery offers higher voltage stability and lower internal resistance in comparison with a conventional lead battery. For the driver, this translates into shorter response times and an improved auto start/stop function. Even when the battery charge level is low, the higher performance of the new power store also enables much longer operation of energy-intensive and electric on-board vehicle systems, such as the sound system, with the combustion engine switched off. This means fuel-saving stop phases can be activated more frequently. The LiFePO4 battery has a service life of up to 2.5 times longer than lead-acid batteries and offers up to seven-times higher cycle stability. Thanks to the advanced battery technology and power density, 20 per cent less space is needed and the weight of the on-board battery is reduced by more than half, from 27 kg to 12.75 kg. These features made it possible to reduce the 95 Ah capacity of a conventional lead-acid battery to 60 Ah for the LiFePO4 battery.

This video has already been posted in another thread, but I thought it would help to repost here. It specifically covers How to jump start the 992 and the lithium ion battery too.

No, he’s saying that you have to wait 15 seconds to allow the battery’s internal sensor to close the relay which will reconnect the battery to the electrical system, then you can jump start the car.
