..but not INSTALLED in automotive untill 11.

Auto dept might close sooner than store close time, try to call the location and verify

Yes, you can

Yes. I have done it.

I believe automotive closes at 9.

They close auto and other provision centers like electronic n all soon..but you can try getting assistance there..

I believe batteries are also available in the main store area, if you know which model will fit your vehicle.
