When to replace battery in GMC Duramax Diesel?

GP cascading (replace one, then next week another, etc.) failure is commonly experienced around the time you also have a battery failure. And when 1 in the pair fails, it’s usually the pass side. Heat, not frigid, kills batteries.

What causes a Duramax battery to wear out?

Any difference between the batteries’ open-circuit voltage will induce current from the one with the higher voltage to the other one, which will prematurely wear out the higher-voltage (newer) battery. Just happened to me. Passenger side was fried but the other was carrying it.

How much does it cost to replace a Duracell battery?

Thank you all for the very helpful information. Did two Duracell 78’s yesterday.. not bad, maybe 30 minutes. 800 CCA and $233 for both out the door at Sam’s Club. 3 year replacement which is about what we get here in SW AZ… I am thinking it is time to be proactive and replace my original batteries before I get stuck in the boonies.

Which is the first battery to go bad?

Always 1 that goes bad first. Not sure if it’s been said already but always replace the batteries in pairs, even if one of them passes a load test. Any difference between the batteries’ open-circuit voltage will induce current from the one with the higher voltage to the other one, which will prematurely wear out the higher-voltage (newer) battery.

Which is the best battery for a Duramax?

Stand up really well to vibration and bouncing too. I prefer the Optima batteries, but just replaced my two with AC Delco batteries a few months ago due to overall cost. Optimas would run me about $400 for both and the AC Delco with 780 CCA was about $200. The Optimas don’t leak and no battery corrosion is a plus.

Are there any problems with the LLY Duramax?

In terms of LLY injector problems, GM had sorted out the internal failures with the 2004 ½ redesign, but the LLY Duramax would occasionally exhibit a trouble code for the injectors, but in most cases it turned out to be an issue with the injector harness rubbing through and causing a short or open in the wiring.

LLY Duramax trucks don’t suffer from the same injector failure problems that LB7 trucks frequently had. Instead, many LLY Duramax problems stem from overheating. A new variable vane turbocharger and an EGR system were also added. Check out our LLY Duramax Specifications chart below for detailed information!
