Batteries - Diesel Trucks
I wanted to solicit a few opinions on batteries. My 2015 Ram is on it's original set of batteries, so about three and a half years of use and a little under 50,000 miles. I haven't had any failures ...

2015 3500 CTD with 52k miles no problem with the batteries, so far. Probably just jinxed it.
Mine acted very strange when the batteries were older. When cold, I would get a rythmic discharge cycling on my V meter about 5 times as fast as the grid heaters. You could see the lights dim and brighten very quickly (it was NOT the GH's). It didn't seem to hurt anything but I eventually replaced the batts and the symptom quit immediately.
I also noted this exact same symptom on my 12, but when I read my manual it states that its normal after startup for headlights to dim and voltmeter spikes as truck warms up first minute or two.

He said it wasn’t the grid heater, it was more rapid than that.
