Bests & Worsts Reviews from Amazon

I'm a Framer, and was a dewalt fan, and would say we gave these 60v batteries a fair chance, but I bought 2 of the 9 ah batteries to use with 7-1/4" skil saw and the reciprocating saw, batteries lasted about max 2 months and some were barely lasting a month, and they all did the same thing, they would be working perfect and boom I would put one in the charger and it would not charge, and dewalt warranty would always replace them for free, but would have to wait couple weeks to get them and finally got tired of that, and finally bit my dewalt pride and went and switched to Milwaukee, and have not had 1 problem so far....will say the dewalt has more power then Milwaukee, but am happy I don't have to be running after batteries all the time...do still run 20 v dewalt drills, hope dewalt will get this problem fixed
