Great suggestion. I'm battery challenged, but fortunately not adventurous until I know what I don't know, I tend to err on the side of extreme caution. I've bought/gotten a few mods - with no enclosed info. Since batteries are crucial to our mods and the use and care of correct batteries are 'need-to-know', your suggestion (and the wording of the heading) would get the attention of and inform the largest segment of this forum. I'm not a fan of non-replaceable batteries, but, to protect consumers and mod manufacturers, I'd like to see warning notices included with every mod sold. It wouldn't have to be WARNING in big, red letters - just information about what batteries are recommended and some info about the proper care of batteries. I've learned what little I know about batteries from informed posts on this forum. So thank you, everyone who takes the time and effort to educate me.
