GT3 battery woes
Discussion
I think once they have gone completely flat more than once they are generally done for and I think the lifespan is only about 6 years anyway. Other experts will be along shortly I am sure. I would have taken it for a longer run than 20 minutes (30 to 60 mins). Also I would try the trickle charger on overnight basis and have a look the next day.
With the engine running the voltage at the battery should be between 13.5v and 14.7v otherwise maybe the alternator isn't doing its job.

Hiya, if it's a 2018 GT3 (nice car but a 991.2?) battery has probably failed through age. I've had some success using a CTEK charger with a recondition option to revive batteries - I use my 2015 981 GT4 battery to power electric fencing and it is still going strong despite sitting in fields in sub zero by regular use of CTEK's recondition programme.
The Liteblox battery I bought for my GT4 is now running happily in the GT4RS after about 6 years of ownership. These, and the Antigravity equivalent - which are more competitively priced - have run flat protection and can restart your car if you let this happen with, it seems no ill effect.
If you are like many of us, limiting the miles while this bloody rain remains unstopping, maybe a new battery and get a CTEK charger attached to it directly under the plastic tray in the frunk and your battery will last forever!
I have read here that Porsche can disclaim warranty claims if you don't fit their battery; when I bought one from Porsche West London, it was about £300 - mybe you can get a PCGB discount. It's a lot more than a Halfords job but.....
A Liteblox is roughly £2k and an Antigravity is c£1k. I see that ninemeister has launched a Lithium battery range too.

The thing I find a pain is even where charged, when a battery starts to age this can't easily be detected with a simple voltmeter because the battery needs to be under load to show its true colours.
A useful tip I learned was that the battery voltage when starting the car (under this load) should hold over 9v which is the voltage required by most ignition circuits ... the danger often at the end of battery life is that the car will start if it starts first time but if this fails you are really stuck.
