It was then again discharged or 58.5 ampere hours were realised. The charge was then repeated as above & a further discharge realised 59.5 ampere hours. The battery was then charged again at a constant current of 6.0 amperes & when discharged realised a capacity of 56.2 ampere hours. This shows that batteries can be satisfactorily charged to this characteristic although they do not reach such a high P.D as when charged at a constant current. Signed g.J.
