Vibrators.com recently performed a comparison test of batteries to see which brand lasted the longest in vibrator applications. Energizer won. In our vibrator endurance test they lasted slightly longer than the other premium brand and much longer than generic batteries.
In our test we experienced about 26 hours of continuous use from a set of C batteries.
