Actually the opposite is true. You'll get longer life with shallow discharge/charge cycles. The only reason to do a full charge/discharge is if the battery contains a fuel gauge and it gets out of calibration which isn't uncommon with laptops. Cheap lights don't have sophisticated fuel gauges in their batteries however so you're better off charging every day.
edit: Sorry, I didn't read the rest of the thread where others said basically the same thing regarding charging Lithium batteries.
