<DIV><FONT face=Arial size=2>Hi, list.</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2>I'am looking for backup batteries for some
low-voltage cmos ram.</FONT></DIV>
<DIV><FONT face=Arial size=2>Never used low-voltage devices before and
wonder what way to go.</FONT></DIV>
<DIV> </DIV>
<OL>
<LI><FONT face=Arial size=2>Is there a special data retention mode like on old
fashion cmos?</FONT><FONT face=Arial size=2> <BR>If so, what will be the
maxium backup voltage</FONT><FONT face=Arial size=2> <BR>(the
devices operate normal down to 2.2V).</FONT><FONT face=Arial size=2>
<BR>The data sheets I have are not clear about this point (if the point still
exists o'cause).<BR></FONT><FONT face=Arial size=2></FONT></LI>
<LI><FONT face=Arial size=2>What should be the better pick: NiMH or
Lithium?<BR></FONT></LI>
<LI><FONT face=Arial size=2>Also in the case of NiMH:</FONT><FONT face=Arial
size=2><BR>Some packs list 20% of the capacity for 7 hours for optimal
loading,</FONT><FONT face=Arial size=2> <BR>others 1mA continues
charge.</FONT><FONT face=Arial size=2><BR>Does this matter</FONT><FONT
face=Arial size=2> or can both methods be used on all NiMH's?</FONT></LI></OL>
