Can these batteries be salvaged?
I was given these two Gel batteries but they are not taking a charge. Is there some way to recondition them so they can be usable again?
These were installed in a solar cell and wind generator remote radio relay tower. They were new when put in. The wind charger was at first hooked up wrong (Not me who did that) and the batteries kept going flat until it was corrected. They did freeze once but after being pulled and brought inside they took a charge and worked just fine. They only had a few months of operation when the tower was blown down and the project was scrapped. The batteries and all the other stuff went into a store basement. Now, 2 years later, I am given these batteries but they will not charge. I don't know what might have happened to them in storage. Physically they are in perfect shape. I left one on a battery charger for 1 1/2 days and its still dead. My meter does show it has 10.3 volts across the terminals but there is no real amperage. The other one I put on a better charger and set it to recondition the battery. It ran for 24 hours and that one is also still dead. These are sealed, non spillable, maintenance free batteries. Is there any way to bring them back from the dead and get them working again?
