i have the m2a, it takes both types of batt's, they plug in NICAD and u can put AA's in as well so no problem, i had another one last yr which was stolen, i forget the name but it was sweet, basically same as what i have but it also had a plug in for a cig lighter, i got it at west marine on sale for under a 100, good deal, i got my latest icom for 50 off usedvictoria, good luck in you search
