Truck Bugout bag

[StagLefty]

I've used these for my CR123,AAA, & AA. They're not a have to have thing but they keep the batteries separated . My current ones have been in my pack for a couple of years now.

As far as the candles go-if their stored in extreme heat I don't think there's much you can do. I usually make a habit of going through my truck bag every few months and check on the status of gear.Rotate MRE'S etc.
I've had a few runny energy bars.
