<DIV>This sounds like an ideal customer for AGM or GEL batteries. Far more
efficient and no maintenance required. One thing for sure, I would check the
programming of the Trimetric. You can undercharge a battery and never know it
if the configuration is not done properly. Make sure to calculate and use P1,
P2 and P14 to determine SoC.</DIV>

<DIV> First off this pack is a 2.3 hour
round trip drive from here, it's winter so most of the charging would be her
AC genny, the customer is in her 80's. She has been recording SG's but I
discovered she would take them without regard to battery SOC reflected in her
Trimeteric, so they are useless. I did not check SG's while I was there
though I started the generator soon after I arrived to try and do just that,
but it was taking too long to get to even just 28 volts much less some
fully charged voltage for a couple hours.</DIV>
<DIV> </DIV>
<DIV> From all your responses, my sense
is to install a new pack. Part of me loves the challenge of trying
to"save" a pack that's on the edge of a (sulfated) cliff. However, she
is not capable of some of the tasks required those times when I'm not there
(watering cells, adjusting voltage settings according to SG response to long
charge times, monitoring temps to prevent a catastrophe, etc) This could
evolve over the course of what would easily be days, probably weeks of
culling/moving batts around in the pack, swapping cables, adjusting set
points, swearing. The cost to benefit ratio probably doesn't add
up.</DIV>
<DIV> </DIV>
<DIV> Thanks for slapping me upside the
head on this one.</DIV>
