<p style="margin-top: 0; margin-bottom: 0">
<font face="Lucida Grande" size="3">Given the time in "storage" the cells will be severely sulfated and will not accept much current initially - probably 28A max (1400x2%) and 70A (1400x5%) will suffice once current is accepted. A standalone "unregulated" charger or constant current would be best to reclaim these or at least get things started.</font> </p>

They were connected up in a system that was never turned on (long story). I believe these batteries can be recovered if I can get a high enough amp charge into them. The battery mfg. recommends putting a 200 amp charge on until internal temp rises to 40 degrees C then let them cool and do it again, maybe 15 times, to blow the sulphates of the plates. Unfortunately I don't have a 200 amp charger but I do have an Outback 3524 inverter with an 85 amp charger. I'm wondering if I can force the inverter to maximum charge to accomplish this. I hooked the inverter up but the batteries only have about 10.5 v output from the batteries (hooked up 12 in series for 24v). For this reason the Outback won't power up. I am wondering about using a standalone charger to provide power to the batteries -- which will also provide power to the inverter -- and allow it to come on and charge. Anyone suggest a better way?</font></span> </p>
