Batteries have quite a gurgle

Edited out my confusion--now clear that HCL is 210 and ECL is 225.

See above--did you get Trojan T-605s for $83 ??? :)

Seems to be a new line-up

Compare with T-605 for 210 and T-105 for 225

Hmmmmm--does Interstate have a new source for its GC2s?

Note here on Interstate site, link to GC2 gets you a Trojan page.

Just reading what the label said as a reference point. BTW $83.99

Costco item number 850284

What's an Interstate 210? They used to be 208, 232, etc.

Four new Costco/Interstate GC2 210 a/h today has cured the issue. :B
Long overdue. Solar had them topped up so much faster... made a real difference.

I'm sure a couple (or 6) new batteries will be a very pleasant return to the capacity you expect.

Definite loss of capacity. I think the solar has been masking the issue for some time. Yes I am concerned with potential expelling of electrolyte or worse.

Thanks again MEX for the explanation.

Fiberglass mats can clog with shedded plate. Avoiding hydrodynamic theory let me put it this way...older batteries can gurgle. I have seen GC220's burp so bad undergoing a 40 ampere charge they expelled electrolyte out of an opened cap.

Guesswork always loses. Without total kWh usage data and maintenance values is it not pointless to ponder the exact state of the batteries? Seldom cycled properly maintained GC's can endure a dozen or more years.

Carbon pile load test, hydrometer analysis, and impedance testing is the only way to get a grip on the state of these accumulators.
