<div class="moz-cite-prefix">When I had batteries reverse polarity
they quickly turned around but never had their capacity after.<br>
2nd, that is a clear indication of a DC drain that can kept
draining all the way to zero. The strongest batteries keep giving
voltage, while weaker batteries give all they have and become
resistors. Its really a horrible situation that I have since
avoided with LVDs, etc.<br>

<div>I visited the customer's house yesterday to set up a pulse
charger. Much to my surprise the three batteries that
originally registered negative voltage are now reading
positive. Does this make sense - are batteries able to shift
between negative and positive voltages at such a low charge
level?</div>

I second tump.<br>
Most likely a bad /cell battery took out the system.<br>
As these are VRLA batteries, I'm curious do,the cases
look damaged such as expanded or sunk in?<br>
