You probably get 3-4 hours on a fresh set of batteries. If you remember to turn off the radar setting it lasts a lot longer. Also I don’t think f class rules allow the use of a chrono.
I have no idea how long standard [AA] batteries last, I've never used them. The USB rechargeable battery I use lasts a long time. I've never gone through more than ~25% (one single indicator light) of the charge during a range trip, many of which last at least 2-3 hr. As noted above, I turn it off while the barrel is cooling, or while the range is cold for target change-out. The LabRadar is not allowed on the firing line during F-Class matches. If it were, this USB battery would have no problem recording for 3 x 20 min strings.
