It's the second battery of the same model that I buy. Good charging capacity and excellent durability. The comment I made for the first battery is good but proved incomplete. These batteries are initially planned for Black and Decker drills, logically block for charging original B & D: or the battery power to sink into the base, the plastic shell of the "foot" is too strong of 1 mm without a doubt. Poor contact and great difficulty in removing the battery charge termination. Too bad, hence 3 stars this time. For cons, I have no problem charging my two batteries because I use the charging base my Dewalt drill, more powerful and faster, and for the same battery model.
