These could sometimes be 'fused apart' by shocking >(zapping) the cell with a heavy current / high voltage for a second or so. IIRC the other cause of symptoms attributed to the 'memory effect' is overcharging of the batteries. This was *sometimes* slightly improved by fully cycling the battery packs hence the commonly bounced around 'cure' of memory effect being fully cycling the battery a few times. - Raymond --- /~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\ | | "Does fuzzy logic tickle?" | | ___ | "My HDD has no reverse.
