hi ya , as we are all holed up without being able to go for any kind of journey and i m not able to trickle charge the battery does anyone know how long it will last , my old porsche would be flat in 21 days for sure

I think a lot depends on different factors from age and condition (which are often unrelated) of battery to some element of luck on discharge current
Some folks will come back from a 2 week holiday to a flat battery others will tell you it sits weeks into months with no charge required
Mine's sat 3 weeks and will certainly not hesitate to spin the motor and fire instantly, but will have a low battery warning from now on. Never got to a month as I enjoy the car too much

If you add a signature to your profile with your car details (look at mine as an example), that will help us to help you.

Without knowing the age of you car/battery, we're goosed!

FWIW - if you're really bothered, just disconnect the positive and isolate the battery from the cars' system.

But make sure you know how to get into the boot to reconnect it before you close the lid!

Well remembered!
I use a small plastic trim tool to stop the boot latch from engaging, so it's closed 'ish, bit not latched... Wouldn't do it if outdoors.

You could (in theory) connect some plastic covered bowden cable to the manual boot lock emergency release and feed it out through the left side of the bootlid... I'd need to trial that a few times though as I'm not sure how much force is required to pull it.

Running to the supermarket twice a week would keep it topped up surely?

Better to limit trips to supermarket - less risk of exposure to anything nasty.
