<DIV><FONT size=2 face=Arial>Sounds like you've solved the sore back problem
without over- or under-watering cells.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>I water and check electrolyte level every 2 to
6 months depending on the battery bank's age and use (grid-tie float only,
off-grid daily charge/discharge, etc.). I encourage spot-checking specific
gravity of about 10% of the cells before each scheduled watering and
changing the sampling cells each time. That's only 5 cells of a 48
cell battery. But is that an adequate sampling or am I just rationalizing to
avoid a sore back?</FONT></DIV>

<P class=MsoNormal><SPAN
style="FONT-FAMILY: 'Century Gothic','sans-serif'; FONT-SIZE: 14pt">We have a
couple of auto water systems in use that we connect manually and it takes less
than 5 minutes to water a triple HUP 1690 amp hour-24vdc bank. Pretty sweet
but doing the SG is a bit of a hassle as you have to unscrew each cap. I hear
that there are auto water caps that have a port for the extraction of
electrolyte for testing, but I have not used or seen this
cap.<o:p></o:p></SPAN></P>

pretty good, but sometimes the float sticks open and sometimes it sticks
closed so I wouldn't turn on the water supply unless I was there to monitor
it." He said that his forklift customers schedule 30 minutes for watering -
turns the water on before going to lunch and checks to see if the cells are
full when he comes back from lunch.</SPAN><SPAN
