<p>Interstate is not a long life battery. 5 years is probably
getting near the end. As they age, they start using more water
which leads to running them dry, which leads to killing them even
quicker. The end of service for L16s is usually not pretty. I'd
be checking for dead cells, in addition to Steve Higgins's
recommendations. Whether she can recover them or not, its time to
at least start shopping for new batteries. As this continues,
they'll use more and more water, make more acid mess, and in
general not work as well from here on out. Then, cells will start
dying left and right, and it will get really miserable. Basically
it comes down to how long she is willing to suffer.<br>

<div>I have a homeowner client that takes pretty good care of
her batteries. She has a 5 year old set of Interstate L16s (2
strings of 8). However, she recently didn't water them for
longer than normal and they gulped up more distilled water
than usual (4 gallons). She was unsure if any of the plates
were exposed. She has reported that since she added the water
the battery bank has lost about 1.5-2V (48V bank) of her bank
voltage in the morning. She reported ~49.5V in the morning
before she added the water and now she is below 48V.</div>
<div><br>
</div>
<div>I have advised a good strong equalize charge to destratify
the electrolyte.</div>
<div><br>
</div>
<div>Will diluting the electrolyte make the voltage sag like
that? Is there any other advice you might give her until I
can get up there?</div>
<div><br>
</div>
<div>Thanks</div>
