Water level

How much acid should be above the plates on a lead acid battery?

Thanks for any input

Easy..simple

X4 or 5 or whatever. Got mine back when I pumped gas for a living. Used it a lot back then. Works on both 6 and 12 volt batteries 🙂

Thanks for all the input.

If you don't have room for the 'water jug' then you can always install a 'watering system'




That water jug has been around since, well I'm not sure. But I do remember Full Service Gas Station attendants popping the hood and using one of those water jugs on the battery

That's pretty neat. I'll have to look this up.

The CORRECT LEVEL is that which is low enough to prevent purging at max charging and temperature. It is pre-determined by the manufacturer according to cell dimension and plate percentage fill. Start with a level 1/8" above the plates then check it again after max charge rate charging. If it did not rise a lot add a bit more water. Simple enough.

My original post still stands
Really doesn't matter as long as its above. But why not play it safer,.. keep the level 1/8" below the slots at the top ? But be sure the batt is fully charged before you do that.

Yep, those work great,.....wherever there is enuff space above.

Yup, putting that on the "immediate wish list". They work great.

That is one of the only things I like about Interstate batteries. They are translucent and you can see the levels. A lot of industrial I have seen are this way as well. On these, Min/Max levels are clearly marked.

One mechanic told me that the little ridge at the bottom of each cell-fill was the indicator as to where the fluid level was supposed to be. I've always used that as my "FULL" point.
