How old is it cos mine is giving me other problems with the drill not the batteries. I know of mine and another where the trigger is packing up and the battery holder clip bends and the contacts seperate in use. Never had a problem with the batts
I think the drill is 2006 I've had trigger replaced & a couple off other bits , the 3 lights on both battery's come on when charging but once out the charger & in use won't light up , charger is saying battery ok just not lasting , they only have set amount of charges , have herd china is the place to buy from for replacment parts but struggling lingo , do you know of any where ?
