[RE-wrenches] Battery Damage

[Will White]

Wrenches,

I have a customer who's got a 24V off grid system with one string of 12 two volt, 2000AH Power Battery brand flooded lead batteries.  The bank is about four years old and has been working great except the customer forgot to water the batteries for an extended period.  When I went out to service them the plates were exposed and I had to add about a gallon of water per battery.  These batteries have a large amount of water over the plates usually so I'm guessing that about 1-2" of the top of the plates were exposed which is about 10% of the total plate surface.

So here's the question.  The bank seems to be working fine, is it likely that permanent damage was done?  Is there a good way to test for damage?  Is there anything I can to do mitigate any damage done?

Thanks,
Will
