[RE-wrenches] HUP and Hoppecke batteries - experience, comparisons?

[Dave]

Darren,

 

I have a set of Hoppecke 16 OPzS 2000's in my barn/shop. These have been in
service since 1996 with no problems.  One string of six for 12V.  Receive
light duty, rarely cycled below 80%.  Have added water every 12  months.  I
ended up with these monsters (330 lb 2V cells) by default as Hoppecke
warranted me on a couple of sets of their failed Fibered NiCads with these
LA batteries. I think the  SG of 1.240 (less corrosive to the plates) is a
key to the longevity. With these being so tall (32") I make sure that these
boil & off-gas hard regularly (at least every two weeks) to prevent
stratification.

Hi Wrenches - I know from time to time there is some good discussion on
batteries here.  I've searched the archives and can't find anything much
newer than 2007 in regards to HUP batteries - but maybe I'm missing
something?  We've had some disappointing results in the last few years with
other large deep cycle batteries in the field.  In an effort to increase the
longevity and sustainability of our systems, we are interested to hear (or
be referred to past threads) about HUP or Hoppecke OPzS batteries -
experiences, comparisons, recommendations?  Thanks!
