ABSTRACT:
A pair of vacuum chambers (27 and 28) are mounted on a T-bar gripper (19) which engages the back walls of a pair of adjacent batteries (16). Operation of a knurled, internally threaded collar (23) draws the vacuum chambers into sealed (54) engagement with the battery casings. A pair of drills (66) mounted at acute angles greater than 45.degree. are operated to drill angular holes (71) through the casings into the vicinity of the bottoms of the casings. Application of vacuum to the chambers draws electrolyte from the casings to levels below the levels of the entries of the angular holes into the casings.
