That may be but that brand is heavy duty stuff designed for trucking
applications. It is an OEM brand used on many truck chassis. My motorhome
had the alliance group 31 engine starting batteries, (2). I purchased the
rig April 2004 and I replaced them in 2012. The Trojan House batteries were
replaced November 2011 as one of the four tested bad. The alliance batteries
are good stuff.

Subject: Alliance Deep Cycle? (Grp. 27) Wire To Alternator?

Hi all.

Battery sales person said they're made by Johnston Controls.

Anyone used these?

I realize that a lot of battery longevity comes down to maintenance and
useage but if it's junk or really "average" quality, I'd avoid.
Also.....

The battery is rated at 25 Amps per 180 minutes. Assuming it's typically
drawn down 50%,  Truckfridge running, is a relay isolated and fused #8 wire
from alternator to battery of sufficient gauge?

Neil.
