Huh, certainly not my experience. Maybe it's because the mower is bigger? I've got one of their smaller ones, and two medium/small batteries (one 4Ah and one 2Ah iirc), and never have problems, even with damp grass. Only on the most overgrown day have I gone through both batteries, and thrn the first one was charged and ready.
