From an experience standpoint, I have to say this is not true.
I'd get maybe 5-8 days out of a Rotor before the batteries started to affect the performance. My Spire is still doing just fine on the batteries I got in September, including 10 playing days and quite a few days where I just screwed around with my gun all day.
