These are the newest Bauer20 v batteries from Harbor Freight, purchased them online 2 days ago and just received them today. I own several 5 ah batteries and seem to hold up very well. Got 2 of the 8 ah for my bigger tools since these are supposed to have a bit more power. I will test these 8 ah batteries in another video. Hope this video helps. And by the way everything in this video was purchased out of my pocket. Please hit subscribe and like. Thanks
