Battery Operation
The battery compartment contains
two O-rings. The one farthest from
the light head is used primarily as a
reference; it also serves as a backup
seal. You should be sure both are
clean and slightly lubricated.
Sealed LiOn battery with about three hours
of operation; six hours on half power
