flashlight(2, Batteries, Working)

(on the Net) i only see flashlight(2, 8, 4) being asked, mentioned,

but flashlight(2, 6, 3) is interesting too.

flashlight(2, 6, 4)

flashlight(2, 5, 3)

flashlight(3, 5, 3)

_____________________________________________

A flashlight takes 2 (working) batteries.

There are 8 batteries (on the Table), but some of them may be Dead (and Non-Conducting).

To guarantee that the flashlight gets turned on, what is the minimum number of battery pairs you need to test ?
