I think outgassing could well be the issue with some Nicads: I remember that some of the early AA cells I played with actually had a small vent-hole punched in the centre of the positive cap, and the positive terminal in the usual moulded-plastic battery-holders often seemed to be selectively targeted for corrosion (the use of a brass terminal-rivet to connect to a steel spring didn't help either)
