You can get a decent battery refractometer now for about $80. We got one and it
works fine. Check Amazon. The one we got is an Extech.

Eric,
I kept this in my inbox for awhile, and finally had to ask - where
did you get this information? I have never heard this
recommendation - to charge a taller flooded lead acid battery to a
higher voltage just because it's taller. I guess I see the
I would be more inclined to think it's because of a denser plate material in
the larger batteries
I know surrettes need longer absorbs and I believe a bit higher of a charging
voltage to remain happy
And I generally run the Trojan L16s Just a bit higher than normal

Steve,
Good advice but I'm not at all surprised that most folks don't have a
hydrometer. Frankly, unless you are willing to spend a bunch
maintenance.

Hi Larry,
I will bump up the absorb voltage to 29.6 V. How
long do you think the bank should stay in absorb
at that rate? The bank now seems healthy, with
the bad battery replaced. It does accept charge,
without going high prematurely. The max charge
rate from the array is around C/10.

Drake,
When you said, The batteries usually reach absorb voltage shortly after the
sun hits the array, I wondered if you had more of a problem with that system.
Glad to hear it's not that way.
Absorb time is an issue I have with the design of most charge controllers: They
do not measure
Larry and Tom,
Thanks for the information. I will boost the
voltage and the charge hours for the array. The inverter is good as is.
The batteries charge quickly since they are not
generally cycled deeply. The cabin is only used
for three or four days a week, giving the
batteries plenty of
Hi Drake,
It always concerns me when I hear that a battery bank reaches absorb setting
very quickly. It typically means one of two things: very few AH were removed
from the bank; the battery bank has sulfated cells due to chronic
undercharging. Far too often I find the latter to be true.
Are they too inefficient for off grid?

inefficient? they are better then lead antimony, but are considered 'shallow
cycle', so i never take them down more than 50%.

Hi Tom,
These are Trojan L-16E batteries, 370 AH. They
have a 2 hour absorb cycle at around 29.3
V. There is one series string of 4 batteries in
a small, off grid cabin that is used 3 or 4 days
a week. The system has 980 Watts of PV with an
Outback FM 60 CC and an Outback 3524 VFX

Hi Drake
The first thing I would look at is how the batteries are being charged... Can
they even be charged by the present equipment? What is the Bulk/Absorb voltage
and time? Equally important is the design of the bank... series or
series/parallel and if parallel how many strings. Lastly
