I'm with Mike and Tom. I don't understand a 1V short.
A simple, very simple test is use bulb, current matters. One can take a VOM and attach to one pole of the battery and use the other lead on the top of the battery and read voltage.
A simple bulb test will indicate .250mils or less. time is the variable.
I once told a customer to hold my hand. I hooked a lead to one side of a battery. I held the other lead of the DVOM in my hand and asked the the customer (holding my hand) to touch the other pole of the battery. The meter read 12.6V.
