Gray Material in Battery

rucster

I'm in the middle of EDTA'en some '05 6volts. Can anyone tell me what this muddy stuff is inside these batteries?



I dumped it in a cooler - this was at the bottom

could be a build up of gunk from filling with non-distilled water.....all in all its possible there are several reasons for it at this point i would check cells with a hydrometer and see where we are at but that stuff isn,t a good sign.........................

I was getting < 1.0 SpGv and they would not charge more then 6 volts. 4 of them stayed at 5.8 and one appeared to have a dead cell. I am flushing them a couple times and EDTA'ed 2 of them overnight. I just finished adding new acid and have them (series) on a 12v charger for a slow charge. One of the guinea pigs is the suspected shorted battery. I'll know tomorrow, but so its working SWEEEET!

to get them back you need voltage at each battery at least 6. 4 volts or better....the gravity readings are also a problem they should be in the area 1.25 each give or take a wee bit and they should all read very close togather so if you have 5 batts reading 1.25 and 1 batt reading say 1.60 than thats as problem........keep us updated.........................................

5 out of 6 make it. I screwed one up by trying to dig garbage out of it. NAPA had the acid @ $25 (1.265 SpGv) for 5 gallons.
