Yes but I never carry batteries loose in that pocket, I've seen what can happen. My gonads might look a tad pickled at my age but I wouldn't like them roasted!
It's just like the old saying jeppo. It's not what you've got but how you use it that counts. Even if your vaping through a secondhand MacDonald's straw, if it works for you then stay with it. Don't be swayed by those of us who like to throw in the odd mention of this sooper dooper mod or atomiser that costs a small fortune. Stick with what you're happy with.
