Hi Travis,
I have had great luck with Trojan L-16s. I always opt for the -P, the
lowest amp hour version with handles. Lower capacity usually means more
electrolyte, fewer thicker plates and longer life. The high capacity is
great for floor scrubbers where more capacity means more work done
scrubbing each day. In this use they replace them every year. I
usually get 6 years out of the L-16-Ps with moderate care in my off-grid
house.

Hello All,
I noticed that Trojan L-16's aren't simply L-16's anymore. I can find at
least 6 models. Our local battery warehouse stocks L-16E-AC. According to
Trojan's website it's a floor scrubber battery (like it always has been),
370AH @ C/20 and weighs 100lbs.
Under the floor scrubber they also have an L-16H, P and G.
Under the renewable energy they have the L-16RE-A and an L-16RE-B rated at
325AH (115 lbs) and 370AH (118lbs) respectively. They also have a 2v
battery in a L-16 case now.
I couldn't find any DOD vs. cycle curves on their website so I'm curious if
the RE batteries really are better for RE applications. I remember the
general consensus was that the original RE "optimized" battery was actually
worse for RE applications because they increased the AH from 350 to 390 by
making the plates taller but did not make the battery taller. This left
less room for the crud (sulphate) that fills up the bottom of the battery
case to build up before built up to the point where it took the battery out.
Has anybody looked into this? My gut tells me that for the part time off
gridder the battery that my local warehouse stocks is just fine.
Happy New Year!
