<p class="MsoNormal">Hi Gary;<br>
<br>
I think it would be a waste of time to load test a sealed battery that is 9 years old. Even at only 20% discharge, that battery only has 2800 cycles. At 80% discharge, its 550 cycles. The daily system cycle is probably roughly a 10% cycle, coupled with the
frequent deep cycles. We have been seeing 5 to 7 years in GTB systems with regular sealed batteries. Even in float mode, they don't last forever.<br>
Also the customer has already done a basic load test, and the battery is failing. Its only a matter of time before you start seeing cell failures, and then the system won't even work when the grid is up.<br>
I'd just replace the set on your next trip.<br>

<p class="MsoNormal">You can do a carbon pile test but the best way is testing under several conditions. Here is an option real easy and maybe faster, put a volt meter on each battery under constant charge conditions, higher volts on one battery meens high
resistance in battery, low volts meens low resistance, either extreme can be an issue. Then let sit for at least an hour with no load and check the volts, next put a fixed load on the system, again a volt meter check each battery, here you may find a lower
reading then the rest, there is the problem, now replace the entire bank not just the single battery. This is an easy test and the customer can see it easily too.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">We have a grid tied battery backup system that uses 8 Sun Xtender PVX-2120L batteries, about 9 years old. The grid has been going out frequently – about 4 times in the past 3 weeks.
When the grid goes out, the battery voltage gets too low and shuts the system down pretty quickly. One of the times, this happened within 4 hours. We want to test the capacity of the batteries and we have a testing procedure from Concorde that seems like it
would take a lot of time. Is there a quick way to test the battery capacity? <o:p>
