GMT900 5.3 question

[Retiredguy2]

The OEM Delco in my GMC lasted over 9 years and that was in Michigan winters. I paid $150 to replace it with the best battery Advance Auto sold and that one failed less than 3 years later. So many variables involved.

This is the very reason I change my auto batteries, boat batteries, tractor batteries, ect at 36 months no matter the condition. It's not worth it to me to be stranded and my mechanic swears 90% of the starters and alternators he replaces the people say "I just put a battery in it".

Makes sense. If the battery is weak the starter works harder to turn over the engine which leads to heat, which leads to resistance, which leads to failure. Then the alternator has to work hard to charge a weak and depleted batter. Again, heat and resistance lead to failure!

+1 Today's vehicles depend more on the battery to run and to run correctly than before. There's even a fair amount of talk in a few trade journals of raising the system voltage.

I remember reading in an automotive service trade publication (paper copy) back about 2001 that 24-volt electrical systems were being considered. Thank you for the reminder, but it is hardly a new idea.

Five years on a new battery should be no problem.

Can I come get your 3 year old batteries? To me that is a little over kill.

My boat batteries are well into their 4th year. Just fished yesterday and was on the trolling motor all day long with no issues. The main thing is to keep them fully charged when not in use. That is something a newer vehicle that gets driven regularly does very well.
