Nick;
I'm not basing this information on my own anecdotal experience, its based on
cycle life data from Trojan.
This test data is done independently by the BCI (Battery Council International)
The T105 gets 750 cycles to 80% DOD, while the L16 only gets 600 cycles to
80%DOD.
Obviously, your act
Really Ray:
Almost all of the L-16s I've installed or serviced, mostly Trojans, lasted
7-13 years. I have only seen one one bank of L-16s die in 5 years. On the
other other hand, I have seen golf cart batts, such as the T-105s last 3-7
years, with only a few making it any longer.
Nick
IF those L 16s are much over 5 years old, they could be gone. L16s (of any
brand) have less cycle life than a golf cart battery, just check the charts.
They also don't fair very well long term in float charge.
You can probably EQ them back to life as already mentioned, but then after 6
months to
Wrenches,
I reeaally need to find a bead on BP SX3190B Modules. I've tried all the
big names on the west coast to no avail.
Thanks

That is a tough one to diagnose, but I think you have some sulfation, I have
used interstates and had reasonable luck. They act more like a traction
battery than a RE battery. This might be a job for a desulfator or a very long
slow charge. It takes a long time to get sulfur to leave the plat
Andy,
Contact me off list and I'll send a photo of what we do. This is something I
came up with to comply with Article 690.31. No guarantee your AHJ will like
it. I shared this on list last year, nothing really new. We don't drill into
module frames, but use the aluminum mounting rack to fasten
Bob,
Sulfation, I'd say. Try EDTA. Trailhead Supply. See Home Power marketplace
ad for contact info.
If it's not sulfation then maybe it's simply diluted electrolyte(accidental,
or intentional) which would make the batteries have lower performance AH

Hi, I'm Looking for products or techniques that have been used as a raceway
for wire protection on the back of a ground mount array. The local AHJ is
not accepting a fence. We are required to cover or shield our USE module
wiring below 8'. Side question: if we directly attach (self tappers) a

IMHO Interstate makes a decent battery. It sounds like to me that you are not
Equalizing but just trying to BULK. You'll need at least one robust EQ cycle to
bring the SG's in line and likely 2-3 a couple of days apart. At least the
Magnum's of a couple of years ago are not intuitive to get into
I have 2 systems that I am trying to correct that another local dealer has
installed.
This one is 2 strings of (8) UL-16 HC Interstate Batteries, 16 batteries
total.
We cannot get the batteries to charge over 1.225 despite discharging them
and generator charging them till everything shut down.

I agree w/Don's comments and would add that I'm migrating away from Grundfos to
Lorentz. My main reasons are the poor CS from Grundfos, the inability to
rebuild the pump in the field and the electronics down the hole. In addition
Lorentz has a huge line of DC pumps up to 45gpm and soon beyond ev
I use a non-contact IR thermometer and tag the electrolyte.

Daniel,
Your home auditor should become more familiar with her own test equipment!!!
Hydrogen is well known to cause false positives for CO when using a combustion
analyzer. There are sensors which exhibit _low_ cross sensitivity to hydrogen,
but those are not the rule. I know of no CO sensor
By the way, it was a typo, it is an 8 battery system @48Vdc.
We just put in an order for a power vent, the home owner is going to install
this herself, as she is handy enough and has done PVC plumbing work before.
I will let the list know if this solves the issue or not. Also I plan to

Hello Daniel,
Unfortunately, I've had to deal with this issue in the past and after countless
hours of effort (end-users, fire departments, and my own), the conclusion
and/or corrective action has always been to replace the CO detector.
Carbon monoxide or other carbon oxides are not expected by
Hi, Daniel~ If your client has quantity six of the L16H batteries, that's
only a 36 volt string, not 48 volts. Let's hope this is only a typo.
The only vapor "emissions" likely from a group of floodies are oxygen &
hydrogen...then there's dilute sulfuric acid mist...but no carbon
component.
