NiCad? where are these batteries.. They look like lead acid batteries to me.. the "frosting" is acid spillage once it has been charged...
NOTE!! Appologies… After a bit of googling they are Ni cad... Never seen top-upable ones before... Still warm water removes this corrosion.. Still looks a tad overcharged though..
Yup, Ni-Cd batteries and they are used in UPS for a telephone exchange. I am pretty sure no acid reached the cap. Do you mean some vaporized acid (if that is even possible)?
Reading further... They shouldn't do that... The top is a flame suppressor... They are called "pocket plate ni-cd batteries" But nothing should get out as they have anti overcharge capability.... I hope someone in your company didn't think they were lead acid and topped them up....

Overcharging is not possible.. these thing are supposed to be nigh on impossible to break ( fool proof ) if the electrolyte has escaped a bit there must be a reason... Clean them with warm water and see if it re-occurs...
