Re: Battery electrolyte leakage detectors? (acid/alkaline)

In principle any form of pH paper would change colour, providing it is not bone dry. The real problem is that by the time you notice that the paper colour has changed a considerably amount of damage has probably been done. There are continous electronic pH sensors available, but using them would be really gilding the lilly, as they are horendously expensive.

maybe some sort of sensitive litmus paper that would detect
