BATTERY REPLACEMENTS FOR
THE MILITARY STROBE LIGHT
By: WildCard1
Once the military battery goes dead, remove the brass tail cap from the old battery; be sure to clean out the inside of the cap. Install two lithium CR-123A (3-volt) with the positive side (+) up or to the brass cap.
.. and last add a rubber O-ring to the brass battery cap. There should already be one on the tail cap; the extra one gives the needed space to not crush the civilian batteries and it gives a good seal at the battery port.
The strobe will only run for about an hour on a set of batteries, but the price is right and the batteries are readily available at any hardware store.
