Did a test.
New Duracells and a bunch of old batteries (Duracells, energizers, and workaholics) from my recycle bucket:

All these batteries are sold as 1.5 V batteries. They usually start out as 1.6+ volts.
I bounced them on a glass table, over the place where the glass is supported by one of the legs.

                                  number    meter voltage
non-bouncers:
Duracell AA:                  12          1.593, 1.617, 1.616, 1.615, 1.620, 1.618, 1.620, 1 .618, 1.617, 1.614, 1.620, 1.617;
                                    average: 1.615

Workaholic AA:              2             0.484, 1.335;    average: 0.909

workaholic AA:               3             1.339, 0.192, 1.339             average:  0.956
