  • Legit Milwaukee m18 12 amp /hr batteries from Jeff’s garage .
These batteries came in the Milwaukee packaging and are the real thing . Finally ! My last purchase from a seller that is no longer on Amazon thank God ! Sold me 4 counterfeit batteries . They work in my carry on all except for one for now with no warranty . These 4 batteries are brand new , which means I get the full 3 year warranty as soon as I register them . I’m very happy about my purchase ! I will order more from Jeff’s garage . ... show more
