Hard Cell

[Dunc B]

I don't get to use my April '96 reg Chim very often so always have it connected up to an optimate which usually gives a green "fully charged" light within a few hours of connecting.Recently it's been taking 36hrs or so to go green and "iffy" starting.Checking battery level as i assumed was done on service was first time i realised battery box has to be removed completely after disconnection and de-rivetted to even see that all cells were dry.Have now topped it up, charged it,discharge tested it O.K.Surprised to see it's marked wk52 96.Original?Do dealers ever touch them on service?Must refit tomorrow and see if all is well,if not
