today was battery day... I was showing a friend a weapons light the other day, and discovered a dead cr123 battery... embarrassing...so much for the advertised long battery life... ordered a 12 pack, and they came in... checked the voltage on the other lights containing primary cr123s, which were all good to go....checked the charge on my lone 18650 light, and was still good after 3 months....I've got a couple of months before the beginning of hurricane season... then will go through the stored water ... need to find a one pot replacement for Dinty Moore Stew as my local Sam's doesn't carry it any longer
