6 mos ago I bought two grp 27's because that's what would fit under my step.
So far I'm very happy with them. Power wise, they seem to perform as well as my previous pair of DEKA 8A31DTM AGM Battery in grp 31.
I'm a light power user and get by charging using 100w of solar and my genny as a supplement. They power me all night during 25F temps running the furnace all night plus lights, water pump, detectors and fridge on gas. I also run a 15" DVD player For 2-4 hrs or so each night watching movies off those batts. My morning voltage is usually around 12v to 12.1v when I kick on the genny .

Amazon has the Universal grp 27 AGM for 179.00
Universal Power Group 12V 100Ah Solar Wind AGM SLA DEEP Cycle VRLA Battery 12V

Dimensions: 12.17 inches x 6.61 inches x 9.16 inches. Weight: 63.93 Lbs

That is a very interesting consideration. I wonder what it's physical dimensions are.

A quick search, I found this.......Group 31 batteries are approximately 13" x 6-13/16" x 9-7/16"


That's a good battery, its actually made by DEKA. They are really hybrid batteries not true deep cycles and that's fine for most people. You might only be able to fit one under a class c step due to the width, that was the case with mine, which forced me to go with a pair grp 27's for more amps. I also lack the height for GC-2's.


FYI....I guess im a little behind the times regarding Trojan , I only found out that Trojan is no longer made by a private company , its been taken over by C&D Technologies.

"Nov 6, 2018 - C&D Technologies to acquire Trojan Battery Company. Trojan Battery Company's current majority owner, an affiliate of Charlesbank Capital Partners, has reached an agreement with C&D Technologies, a portfolio company of KPS Capital Partners, for C&D Technologies to acquire Trojan".

FYI....for those considering T-105's .

bulk charge rate is 14.82 when at paired 12v's , I assume the proper converter would be needed to achieve that. I have a PD-4000 and not sure.

this was copied from the T-105 pdf

CHARGING INSTRUCTIONS
CHARGER VOLTAGE SETTINGS (AT 77°F/25°C)
SYSTEM VOLTAGE 6V 12V 24V 36V 48V
Bulk Charge 7.41 14.82 29.64 44.46 59.28
Float Charge 6.75 13.50 27.00 40.50 54.00
Equalize Charge 8.10 16.20 32.40 48.60 64.80
