Are AGM batteries worth the extra money?
Warranties seem to be the same.

The original in my durango went eight years, so i went with another AGM. It is also a pain to change it out.

AGM batteries last longest with the correct charging voltage. They also don't like to sit partially charged. Modern cars are programmed to reduce charging output from the alternator after about 90 seconds as a fuel saving measure. This does not help AGM's, which like to be charged at around 14.7 volts, if memory serves.
On my 2008 GMC 2500HD gas 6.0, I have two AGM's and a pretty heavy amp load for the stereo. I learned about this issue and found an interesting solution. It involves a Sterling Power DC Input Battery Charger, which charges the batteries at the level that's best suited for them.

Yes a Mopar Battery. I did not want to push my luck,thats why i changed it out.
done many in vw/audi or mb that are over 12 years old
but they use a smart charging system that will addapt to a older worn battery
they like a stable load and charge and work well with a constant load of lots of computers sitting for a long time without starting

AGM in my Camaro went ten years (tho not many miles). I put another agm in it (I'm not sure there is a lead/acid for it!).
The agms in my diesel pickup did well, but when I needed to replace em, I bought lead/acid for the same warrantee, half the money. I figure if they last more than half what I would expect out of an agm, I'm ahead.
My Opel has the worst battery access on the planet, I would have definitely bought an agm for it...... but the battery supplier I use didn't make one for my app. So, lead/acid it is.
Bottom line: for me it's application specific. If the agm has no more power, and no better warrantee.......?

The Interstate agm actually have a shorter warranty than their lead acid batteries. At least the mtx line is free replacement for 3 years and nothing after. The mtp line of lead/acid is free for 30 months and then pro rated out to 5 years.
Life got better when I started avoiding Interstate batteries for some reason.
I like AGM batteries, but keep them charged in a car that sits, not a tender or a trickle charger. Charge when Volts go down to 12.4. Don't over do it.

Get a charger that is meant for AGM batteries. I have one from HF and has worked well to keep my red top alive for 6 years now. On the other side we have an Odyssey 20a charger and they thing will bring a battery back to life. My bother has some Optima batteries that are about 15 years old and still running strong…

I need to replace the battery in my Ford puddlejumper. Best thing I like about the car is when I have to fill it with gas, but honestly I'd rather be driving something else so spending as little as possible to get down the road appeals most to me. Time will come to drive something more appealing, the sooner the better.

My Red-Top, Dry-cell technology Optima was new in year 2000.
I finally replaced it in year 2015.
Cheapest doggone battery I ever bought.
Heavy bugger too.... but just right to bolt down over my right rear wheel;
and to think, I bought it cuz it didn't need to be vented, and was thus legal to run in my trunk...... which now, by father time, is ventilated anyway, as rust.

Just can't let them get discharged too much
I have one of the Reproduction MOPAR Yellow Top AGM batteries in my 69. Still working ok since 2014.
Was thinking when it comes time will need something that looks oe
