Batteries?

Or battery cable connections.
2 year old batteries aren't "new" or necessarily good.

Batteries only last about two years in these trucks, because it takes so much power to start them.

The starting power required has little to do with battery live. Heat is the big killer of batteries. Mine usually last 6 years or so, we seldom see temps over 70 degrees. It could be a diode in the alternator, it will not properly charge and will not trigger the ALT light. I have had this happen twice. I would check that once you get it running.

I think.both of you have valid points.

Heat is a killer but I think a frequent heavy draw on a lead acid starter battery also shortens battery life. Such as that from glow plugs and starter demands of a cold engine.

Proper battery and charging system maintenance by making sure all cable connections are bright & tight, cleaning posts, using felt washers, occasionally topping off with a goid charger, etc can all help to protect the batteries.

I have also read the common practice of trickle chargers is also a battery killer.

And, again, you guys are both right, 2-5 years is the typical life of a lead acid battery.

That's why I switched to Odyssey extreme 65-PC1750T batteries, because I was only getting two years per set of batteries. Hopefully, I will get at least six years with these.

Just wondering why trickle chargers are considered battery killers?

I think that has to do with the evolution of trickle chargers. The old ones were simply low amperage chargers - nothing to stop them when the battery was fully charged so they would slowly cook a battery to death. The newer ones have sophisticated algorithms that control the charging - constantly monitoring the battery voltage and only applying current as necessary. I have the NOCO Genius chargers on both of my antiques. They have a very sophisticated charging system and I've got 10+ years on the batteries in those vehicles with no issues whatsoever.
