<div class="moz-cite-prefix">Right Bill. We recommend fully charging
and then an equalization charge on all new flooded batteries. It
takes many cycles on a new battery to achieve full saturation of
all the active material. Because of this effect, I believe it is
vital to reach 100% SoC regularly during the first few months of a
battery life.<br>

<p class="MsoNormal">I have installed/serviced thousands of
battery based systems, I have not seen any reversed cells
either, but I know how it happens.<br>
<br>
Here's a thought on what could cause multiple lower capacity
cells in a bank. >From the moment a battery is not being
charged, including newly assembled batteries, it is self
discharging and lead sulfate is forming on the plates. If
left uncharged or undercharged for months, which could be
date of assembly to date of installation, the capacity could
be affected due to ionic bonding (a level 2 sulfate bond
blocking SO4 from finishing the electrochemical process by
discharging its electron to Pb). Simply put, less surface
area is available so there is less capacity. Unless the
installation date is within 60 days or less of the
manufacturing date, this could happen.<br>
<br>
If these damaged batteries were then mixed with healthy
ones, this could account for multiple low capacity cells and
the scenario I described in my previous email would apply. <br>
