[RE-wrenches] Electrolyte level measurement

Wed Feb 28 12:35:18 PST 2024

And to add to Steve's good advice, make sure the sprayer has a plastic 
wand. Some are made with brass
wands and that can add a degree of excitement that I can live without.

I also only fill when the batteries are mostly charged. That lessens the 
chance of the cell being overfilled
as the state of charge increases. Oh...and a headlamp helps to see the 
fluid level, just cock you head
and you'll find just the right angle to see the fluid.
