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?</span></span></font><div><font class="Apple-style-span" color="#333333" face="'Trebuchet MS', Verdana, Helvetica, Arial, sans-serif" size="3"><span class="Apple-style-span" style="font-size: 13px; line-height: 18px; white-space: pre-wrap;"><br></span></font></div><div><font class="Apple-style-span" color="#333333" face="'Trebuchet MS', Verdana, Helvetica, Arial, sans-serif" size="3"><span class="Apple-style-span" style="font-size: 13px; line-height: 18px; white-space: pre-wrap;">Ron Young</span></font></div></body></html>
