How often do you check your stored kit?

[NorthernRaider]

I always keep my batteries outside the device they are intened for cept my EDC flashlight, i believe anything with a circuit can slowly drain off a battery, not to mention leaks, I also only buy batts with expiracing dates on em like Duracell Ultras and energiser lithiums, had no success with rechargables. I tend to go through the kits around the 31 st March and 31 st Oct each year, or if something big kicks off.
