Ron,
I'm going to reiterate what Jeff says here. It is similar to what I had
said in my email. The charge rate must REGULARLY be C10 on the KS
(5000 series) batteries. This means, on KS 25's, a routine bulk
charging rate of 135 amps. I find that on these types of hybrid
systems, while the

I asked Surrette about their lead calcium batteries this morning, right after
reading your post. Here's their reply:
I'm afraid our flooded calcium line is not yet available. Product testing went
very well but at this time our present high demand for our other product lines
has prevented

Hi Daryl. I've got other KS25's in hybrid systems (wind gen solar) that seem
to do fine over the last several years. The Ouback 3524 has an 85 amp charger.
There was no problem getting to 32 v and holding it for eight hours. This has
been done twice now. Larry and others attribute the
sure you are getting the picture.
Also, why have you not installed a battery monitor yet? It will give you
eyes into the battery and spare countless hours of time diagnosing the
problem.

Ron, you have misquoted me so yes you are wrong. It is not about getting to 32
volts. Go read it again.

You're correct Larry, my apologies. Been burning the candle at both ends.
Thanks for your input.

Ron,
This reply a little late since I have been off line a few days. I mentioned
in a similar thread last year that I had an off grid home client I designed
and installed in Idaho back in 1998 that had a Kohler 8.5 kw generator, a
Trace 4024 inverter, two separate solar arrays and Outback
I digress but... the best battery for grid tie with backup is not lead
antimony, but lead calcuum. Surrette makes these too and they use next to no
water and have a much longer warrantied life.

Ron,
What comes to mind for me is that Surrette 5000 series batteries like
to have a regular charge of C10. KS25 cells are rated for 1350 ah,
creating a need for a somewhat regularly occurring charge of 135 amps.
I do believe the batteries are not ever getting that, except for very
rare
Hi Ron,
Here is what I would do.
1. install a amp hr meter
without this you have no idea of what is going in/out. So when they mention
the batteries drop rapidly to 22.8, they can now see how many amps are going
out.
2. record voltages to 2 decimal places of each battery when these anomalies
monitor yet? It will give you "eyes" into the battery and spare countless hours of time diagnosing the problem.Larry

Folks, this one really has me puzzled. The client has done regular two hour
EQ's, at least once a month. When did a site visit and I topped up the
electrolyte (they'd been starving the batteries for water but always just above
the plates) the problem seemed to go away. They were satisfied that
Hi Larry,
I immediately assumed sulphated battery when I heard the customers description
a couple of weeks ago but the hydrometer readings didn't jive. Any sulphated
battery I've encountered, and I defer to your greater experience, has always

Ron,
You have made a connection that I would not have made, and while I may be
wrong here, it has got me thinking. I have never equated low water level
with SG, nor have I ever read in battery maintenance guides that I should
maintain a particular water level before measuring SG. I'm not convinced
Ron,
Sorry to beat a dead horse, but a Pentametric will reveal what happens at 4am
(or any other time). At a minimum all you need is the sending unit, 2-3 shunts
and the serial converter. You then use your laptop to download and analyze what
happened in the past few days, etc. of course, the

Battery voltage readings are deceiving because they do not indicate capacity.
