<P><FONT SIZE=2 FACE="Arial">On a battery back with 4 - 12v HUP 1690 Ah wired for 48VDC, I went out the other day and "charged" up the bank and give it a fair amount more at an equalizing voltage.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">I checked the specific gravity pretty much right away with the batteries still warm and bubbling. All cells read about 1.260, except a single cell that appears to have an graivity of 1.000.</FONT></P>
<P><FONT SIZE=2 FACE="Arial">Is this normal for a single cell in a bank to crap out completely while all the others remain in fairly good condition?</FONT>
</P>
<P><FONT SIZE=2 FACE="Arial">The bank is 6 years old and has been equiped with a Watermaster system from day one.</FONT>

<P><FONT SIZE=2 FACE="Arial">I can't believe that I have somehow washed out 3 gallons of electrolyte by overfilling or something.</FONT>
