Nope, don’t send me the ETDA Tim got enough goin on. Most I’m gonna try with this battery is what Jerry suggested, drain it all the way down and slow charge it a few times. If it don’t come back I’ll just pitch it. I just planned on using this one at the radio bench to power up 6v radios anyway.
Don’t doubt the Optima is a good battery, just don’t like the looks of them or the color. Picked up a Hydrometer at Farm & Fleet store this morning, looks like the one you linked to at TSC but it has a thermometer in the glass.
Enough time spent on an old hunk of lead, moving on to the next project.
