OEM milwaukee batteries-Get 'em when on sale

OEM milwaukee batteries are the best. Much better than after market batteries. Can't beat a sales price of $105 for two 5.0 mAH batteries (no charge included).

Great Deal.

When I seen the ad that Walmart was selling a two pack of M18 5.0 batteries for just over $100. I jumped on it and ordered them great deal. I had received as a Christmas present the Milwaukee tool portable air compressor and an impact gun and only one battery for both. Now I can have one in each and a backup ready.
