Battery Question

[spareparts]

reel, just drop the leads in the water, check voltage, each one from cell to cell should be a little over 2 volts( thats why there are 6 of them), kinda like a compresion test for batteries, you can find out which one is bad, but you can't do anything to fix it. I did see a battery on a trawler that used independant cells, had a manifold water distributor with a recovery tank so you never had to topp off the water, if you had a bad cell, you just replaced that one cell, look very expensive
