Will car start after 11 weeks standing

Alfrescodave

Assuming that you're having to pay for 11 weeks underground car parking; would it not be cheaper to arrange a taxi drop and pick up ?

No, car will be at home!

This makes it even simpler (or at least, removes some of the complications) for you to disconnect / isolate the battery while you're gone.

Edit to add: is this your model of car? If so, the problem might have been solved already by Hyundai:

Thank you QB. I think it is.....

I am away from the car at present but will check tomorrow.  It certainly would be a good solution to start it using the reset button and then drive around for an hour to charge up.

Assuming the starter battery is some form of lead-acid, letting it discharge to the point where it won’t start the car is likely to ruin the battery.
As others mentioned, ask a dealer how best to avoid discharge while parked.

OP if you have doubts re your battery integrity unhook the -ve terminal when you park up.

If OP's car is like the ones on the Tucson forum link, it has a LFP 12V battery that's closely integrated with the traction battery. Hyundai has already designed-in a system to disconnect the 12V battery if the car is parked for a long period, and has provided a button to reconnect it.

Checked the Tucson today and it does indeed have the battery reset button which will start the car from the traction battery......

Seems like that's the answer, then!
