I run my lights nearly all the time I'm on a bike, so typically about 6 hours a week (across 2 bikes).I haven't yet changed the non-rechargeables in either of my Smarts, which I've had for over a year. I think that is Potsy's point.
Alkaline batteries, which came with the lights, lasted about 2 months. NiMH ones do about the same but I routinely change them round once a month, that way, apart from one brand, they go on working forever.
