It could be up around 15v or more.
The worse case scenario is connecting a dumb charger to a battery that has an open cell.
That's when the charger could put extra high voltage on the battery, and the electronics in your car.
The stuff that stays on all the time.

??? Generally the absolute max voltage limit for 12v electronics is rather high in the 18-24v area before anything actually becomes damaged. I have owned many many dumb chargers and none has ever been able to exceed
16v, even open terminal no load.
So, Unless you are running a strip of bailing wire out of a 220v wall socket to charge your 12v battery it is nearly impossible for you to get a battery that high. (I say nearly because I have seen some pretty amazing things done but in reality it may as well be impossible)
