Thanks guys,
Roy, I do have an alternative... I have one of your lamps.... and mighty fine it is too! The Oldham is used for guests.... and well, yes, its old and heavy, agreed. After charging, 7 hours can be achieved. Charge it and leave it for a few days, and an hour tops before its dying.
The Battery is the type with the 2 holes for filling on each cell 1/5 the way down from the top. Same as yours Morlock, but with the holes. Its charged in a container, with a papered base, which shows no signs of liquid. It lives in said container, even when not on charge.
It seems to only loose the distilled water when its in use. Its left fully charged (Although it self discharges quickly) but the levels dont change.
I reckon the thing is rotting inside and its time to get rid. My last attempt in making a battery pack ended, just as Mr Fellows predicted, in a botched failure.!
