I was referring to deep-cycle wet cells (lead) not NiCad. I could measure the effect (I forget the _name_ for that effect, it was someone's name from the 19th century) when I had my 2000 Amp-Hour array. NiCd is far more expensive than wet lead cells. However, they may be cheaper than the gell lead cells common in UPS. Wet is far easier to maintain. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
