The only way to do a capacity test is with a load bank over the rated
discharge period of the batteries, it they have a 6 hour rate, use that one.
The 20 hour rate takes too long! Voltage is a moving target and pretty

I know many on this list disagree, but this sounds SO typical for sealed
batteries. It is why I never use em... never! If they are 5 years old, you are
probably at the limit of their life

HI Todd,
I agree that the issue is probably dead batteries.
In regard to the calciums, what is the added cost per life. ie if they cost
3x as much and last 4 x as long when you calc in MX, venting etc, costs might
be pretty close?
thanks,

Wrenches;
I have quite a bit of experience with flooded lead-calcium vs.
traditional flooded lead-antimony battery banks in remote, off-grid
locations, over the course of the last 15 years. As always, your mileage
may vary.
On the positive side, lead calcium cells have a low self-discharge

capacity checker a waste of money.

Perhaps James @ Surrette can chime in about the cost difference. I do not think
flooded lead calciums are much more expensive then flooded lead antimony
batteries.

Lead cadmium or lead calcium? Again, I do not have the cycle chart handy,
but hopefully James can post that.

I've heard the same arguement, as well as its inverse. The battery choice was
the decision
I have a customer with a set of 24 Concord PVX-6480s that have twice failed
during grid outages during the night. No large loads are on the critical
load panel and, since it's at night when they drop to 50% dod, I'm not sure
what's up with them. I plan on cleaning and retightning all the cable
