Hi William;
My now apparently orphaned copy of Maui Solar Software has Pacific
Chloride Brand batteries listed in its data base that are industrial
flooded lead acid batteries. They have very similar performance
parameters as other fork lift batteries like the HUP. I don't have cycle
life info though, but most of those types were rated at 1500 cycles to
80% DOD. You could estimate the amp hours just by comparing physical
dimensions to another brand. (I'm guessing from the Pic a 85-27 size?,
about 1375 AH new?)
I've come across a few old 2 v sets like that (Exide, Bulldog, Crown,
IBE, C&D, ????) that all seem to go forever. I would do a 2 hr load test
just to see what the cells do under an extended, heavy load. You might
have some weak cells, but usually I just keep them in service. They do
eventually go bad, but it's like a golf cart battery deteriorating in
slow motion: you have a little more time to shop for your next bank.

I visited an off-grid residence a few weeks ago to evaluate. They have a
set of batteries that are steel jacketed 2 volt cells that look a lot like
IBE 2 volt batteries. The batteries are 28 years old. Although they look a
little rough (dirty, some corrosion on the upper rims of the cases), the
specific gravity readings of these cells looks like those of brand new
batteries! There are all in the 1.270 range and plus or minus .01. The
batteries say "Chloride" on the outside with a lightning bolt in the logo.
I was amazed. Could this be true with 28 year old batteries. Does anyone
know anything about this type of battery? Are these standard lead acid
batteries?
We are removing a Heart Interface inverter and installing an Outback
(sideways). The client has a Trace C40 charge controller connected to a
pretty modest solar array. I could not recommend he spend the money for a
new FM60 considering how well the C40 is working. I hope I am giving good
advice.
Anyone have any history they could share on these batteries?
Thanks,
William Miller
PS: I have included a photo. I rarely do this so I am not sure it will pass
the server.
