Hi guys,
One of my S-460 Rolls battery show some problem. one of the cell drop out of balance, way out. All the cells SG measure 1.250 when charged except one that show 1.175, It did not use any water at all last month(this cell). I try to do some Absorb and EQ. the bank get too hot before it finished. So I call the dealer who sold me these batteries. He said he has one battery that he can swap it for me.
When I carry my battery to his place. He has three of these batteries, all of them are in bad shape. The SG read 1.150 and the volt is 5.9 volt. He has these battery over one year and never charge them. I carry two come home to see if they can be charged.
I put them on 12 volts automobile battery charger, it charge at 15 amps, I have them over night. This morning I put them on my small 12 volt solar panel system and set the absorb voltage to 16 volts. at 10 am the SG start to rise and by noon it near 1.225 then the rain start to fall. it still charging on a small current. I will try to absorb or EQ tomorrow to see if the SG can reach over 1.255. Do you guys think these batteries still good if the SG can rise to 1.255?
Thank you in advance.
