OK DOug thanks for that in depth post man,much appreciated...Still a little confused here (please forgive)
1st I should have said NiMH,thats what I meant,just been so long since I bought rechargeables I said nicad(went to wally world yesterday and looked at rechargeables and lit/ions batteries,got confused on everything,and posted the question here) HAHA, but these 18650's you are refering to,I just remove the 3AAA holder from my light,and replace with one 18650?(I know this has to be a newb question,but I never even knew my light could run off of anything but 3AAA) But the lit/ion 18650 for longevity,or the NiMH 18650 for rechargeables?Got it.And is the 18650 recharger available at a regular place like walmart?Again thanks,and thanks for bearing w/me on all the newb questions.
