[T] Just to share a passing though, I believe the 'memory effect' was one of those 'tekky myths' (and Nicad / Camcorder sales persons)? *Apparently* it was first spotted in satellite Nicads where there was VERY strict charge (solar panel / sunny side) and discharge (electrical system and dark side) cycles? After MANY of such cycles the nicads showed the memory effect (thinking they were a lower capacity than they should be). This outcome could be easily broken by a charge / discharge above or below the cycle range and 'hey presto' (ish) 100% capacity? I also believe the 'real' case of nicad failure was the build-up of small hair like fibres between the plates (dendrites or summat) effectively shorting the cell out? These could sometimes be 'fused apart' by shocking (zapping) the cell with a heavy current / high voltage for a second or so. Just a thought .. ;-) T i m ************************************************************** http://libretto.basiclink.com - Libretto mailing list http://libretto.basiclink.com/archive - Archives http://www.picante.com/~gtaylor/portable/faq.html - FAQ -------TO UNSUBSCRIBE------- Reply to any of the list messages.
