<p class="MsoNormal">Since the cells stack in series the low voltage cell must be discharged. they are under compression, However If they are disconnected and charged separately perhaps they can be brought back. Are these batteries used in frequent cycles
or just backup power? Lead Acid depends upon overcharge immunity, thee may not have that. If they are not overcharging the good cells the weak cells will continue to discharge until the battery has some very weak cells. <o:p></o:p></p>

<p class="MsoNormal" style="margin-bottom:12.0pt">We have a situation with a customer's Aquion (Understand there's now longer a warranty) I spent some hours looking at the Aquions. I tested the voltage of each cell. 4 out of the 6 stacks had a cell that was
low, in the range of 0, 3, 4, volts, while all the rest were above 6.<br>
<br>
Each of the cells has a test point above the connector. The cells that were low each have corrosion on the positive terminal, such as you see in the photo. Any ideas as to what is causing this? Has anyone seen this before?<br>
