Rolls Surrette User manual
And I thought the Lifeline user's manual was well written and comprehensive.
Roll's manual should be made a Sticky. I think most every question about lead acid batteries I have ever read on this forum is covered here:

Seems like they consulted Mex's postings over the years, and then cut away all the obtuseness and sarcasm.
One thing I find interesting is that they say in a renewable energy PV system, on page 30:
Before I went with the single screwy 31 deliberately lowering capacity to have my 198 watts of solar be able to charge at a higher rate approaching 10%, I started this thread titled, Perhaps capacity is not king:

It details my thinking on this topic with good input from the usual suspects and the acquisition of the Screwy31, so I like seeing it in print from the premier flooded deep cycle battery maker.
Where has mena661 been BTW? We need a report on his L-16's
As far as the lowered capacity, well the screwy 31. Dollar per cycle compared to 2 sets of previous 2 group 27s in parallel, I came out ahead.
Rolls does make a T-1275 sized battery. It weighs 90 LBS, has 136AH capacity, and positive plate thickness of 0.170 or 4.32MM and ~ 1400 Cycles to 50% DOD

The Trojan T-1275 claims 150AH, 82 LBS and unknown plate thickness and 1200 Cycles to 50% DOD.
Can't seem to find Roll's 12 FS 135 for less than about 400$ before tax core and shipping, so A new T-1275 at under 200 smackers delivered, it will be.

The charge current should be
within 10-20% of the 20 Hr AH rate (C20) rate of the battery bank
