12 Solar batteries, Rolls brand Solar Deep Cycle series 5000, Model 2 KS 33P, weigh 208lbs each. They are approximately 9 years old, but have never been used, were to be used for a 24v solar well pump. Kept in storage and checked and charged every year and hold 2.1-2.2 volts each. These would work in a 12v or 24 volt solar system or an addition to a larger voltage system. Will sell separately for $200 each or the whole set of 12 for $2000. Total weight is 2496 lbs, so bring a heavy duty truck or trailer. I can load with forklift.
