Yes, it seems to be random. The idea that the failures are caused by the wiring or maintenance or anything on the user/ installer side is ludicris. I will also second William's comments that Trojan has been less than helpful, and if you're one month past the 2 year warranty: forget about it. This is truely a shame, since we all consider Trojan to be one of the top battery manufacturers. In the past Trojan was known for outlasting competing brands by many years.

Hi Ray

Would that be random dead cells?

Oh I'm going to risk the wrath of Trojan and others, but I can confirm issues 
with the Trojan L16 having premature cell failures within a couple of years 
just as you reported.  We use the T105 RE and have not had problems, but stay 
away from their L16 line.  I otherwise do not know or understand the causes 
behind these failures, but I think this list proves to be at its most valuable 
when we can save each other and our customers needless suffering.
