I have an electric G-van (converted GM van) and it has a 216v string of 34
air-cooled STM-5-200's. I can't find any data on these on Saft's site, but
they seem similar to the 180's. They also have a large "PSA" molded into
the plastic tops across from "SAFT". I assume they were made for PSA
(Peugeot/Citroen). The "STM-5-200" is stamped into the top of the case
permanently on each battery. There is no discernable date code I can see,
but they look to be about as old as the van (1990).

Here is a crappy cell-phone pic:

Everything seems ok with this pack, and I've done 20 miles so far without
them seeming to be near end of charge. I'll keep increasing my mileage over
time to ascertain what my real range is.

The charger that came with the van is an enormous LaMarche 60a charger,
which is microcontroller-based and seems to have been programmed for "Saft
NiCd profile" according to what is labeled on the charger.

The pack is equipped with a watering system that consists of 3 water
"loops", one loop with 12 batteries, and 2 loops with 11 in it. The 3 loops
end in some sort of catalyst block filters that I assume are responsible for
neutralizing the electrolyte should it vent too much. The beginning of the
loops have fill ports with an auto-sealing valve system.

The electrolyte level seems "normal" (up to the bottom of the caps, and the
first time I did a "maintenance" charge, a little water appeared out of each
of the catalyst filters.

I'd love to hear more about your MRE-180 watering procedure if you care to
share, as it's probably pretty close to what these need!

Thanks!
