Yes, they replied within 2 hours..they said that yes a lot of the round batteries are lithium..thats what was confusing me..because the batteries said alkaline. but the number I gave them was fine!...otherwise.. I read you can't put lithium in your checked bag..it has to be in the carry on bag with the posts covered...If they find them in your checked you will get fined....Dang....I think I need some of that rum cream to chill out!!!! I really did appreciate that they got back to me and so quickly..I'm not even sure if I was contacting them in the right way...it was the only contact info I could find..From now on...its Ray O Vac for me!!!
