[RE-wrenches] Fwd: Followup to Surrette Battery Question

[robert ellison]

This dosen't seem to have gone out.

Bob
 I could also add electrolyte to the cells with the lowest SG after all
this, but how much to add is a real crap shoot. Can anyone offer guidance on
adding electrolyte to compensate for spillage?

Hi Alan,
The process is called "acid Balancing" the battery and it is done in exactly
these circumstances.
I have had to do it on occasion on the industrial cells that I work on.I had
a 6 month old 4000" battery ruined from exactly what you describe. That one
had to be replaced. Then they did it again, but we could balance that
one,and bring it back.

You need access to electrolyte in the 1.400 sg range, do you have any motive
power (fork lift) battery shops near you?
That's the best place to get it. If they will sell it to you at all. You
really can't do it with standard gravity acid, it dilutes too much and would
take forever.
If you want to do it I can tell you how, but it involves frequent charges
and is easier to do in a shop on grid power than on solar. Just the same, if
they are not too far away you could do it over multiple trips and days and
get it done. I am betting that getting the pack to a shop is a non
starter....

Seems that I remember from the original post that the site was not exactly
next door.

Let me know,
Bob Ellison
