The curse of leaky alkaline batteries

Having just discovered yet another device with battery damage, I thought I'd raise the subject of switching away from zinc-chloride and alkaline single use cells, to the newer style of low self discharge Nickel Metal Hydride rechargeable cells. They are sometimes called "ready to use" or "pre-charged" cells due to retaining a useful capacity even when stored before retail. They won't work in all equipment due to their slightly lower cell voltage (1.2V vs 1.5V), but do work in most stuff, and are much less prone to leakage. The science of alkaline cell leakage may be down to the natural formation of gas bubbles during normal discharge. That results in a gradual increase in internal pressure that may eventually force the corrosive electrolyte out through the seal. That could be during normal use of a new battery, or it could be a long term thing when batteries have been left in a piece of equipment. Rechargeable cells like NiMh batteries do generate gas internally during charge, but self catalyse it back to liquid electrolyte internally. It usually takes serious overcharging to make them vent.
