[beamcurrent]

I have recovered this battery from a dark corner were it has lain unused for 20 years. It is a 24volt battery of about 20Ah., made from cells recovered from an aircraft battery, now in a stout wooden box.

Now my first thought was to dispose of it, but it's rather nice really. It will need some sorting out, none of the cells are short circuit.

But I am worried about the electrolyte levels which can be seen through the cell walls and the vent plug.

Some cells seem to have more electrolyte than I would expect and some much less. None of the cells appear to leak.

Question; Is there any reason why the levels are so different between cells, I expect they were more or less correct when last used, and can I just transfer the excess to the cells with a deficit?

Regards
