The designer of > this circuit seems to claim that it can revive dead batteries.... I'm pretty sure that pulsed current is a good thing. I implemented it in an NIMH charger, sort of accidentally. I was doing 1C charging of a battery that was connected across a significant load, and stopping once a second to make battery voltage measurements. Turned out that this current load just happened to match up well with the numbers recommended by the pulse charging docs I'd read. It makes sense to me that it would help avoid the smooth plating effects common with lower current charging. Gas buildup, I'm not sure. I've seen docs where they did manometer monitoring of single cells, and their data suggests an improvement. My take on it is that since it's just a bit of firmware, why not? :) -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
