Been using ego batts and dct tanks for 2 years--now two of the batts are not accepting the tank properly---not tightening down enough t allow the tank to even stand up straight. It will not allow the tanks to even make enough connection to fire.. My question is --can these batts be fixed or do they need to be trashed?? Not a big problem just do not want to throw away if I can fix. My apologies if this has been ask before and answered but could not find it. Thanks--
