If i hook two 12v batteries in parallel will the amperage be higher?

And volt be same? will it last longer with two batteries?

If one battery is dead or bad or discharged.... then the good one will constantly drain its capacity into the dead/bad one. Thats why batteries in parallel must be of equal quality.

Yes, you're right there.
But make sure the batteries are the same.
