Why would you want to pay almost $300 for an AGM battery? Regardless of how great it is, you would most likely want to swap it out every 4 to 5 years anyway as batteries have a tendency to just randomly die with age. Just pick one with a good warranty and call it the day. Batteries had gone so expensive recently, I've decided to try out a Walmart AGM for my 17-year-old X5 (pictured below), which have a 4 year free replacement warranty...will see how that goes
I had various batteries over the years and had come to the conclusion that they're all basically the same. Some examples that I could remember (you can tell I'm an old fart with the list):
- Interstate (Exide) - Gone through 2 bad batteries in a row within 1 week and finally, replaced it with a 3rd one that lasted about 3 years.
- Sears Diehard - Lasted about 4 years. Just died suddenly one afternoon. I had remembered that it started the car perfectly that morning without any signs of going bad (no slow start), then went to completely dead in that afternoon.
- Autozone Duralast (JCI) - The AGM lasted 4.5 years until it stop holding a charge. The flooded one went 5 years before I preemptively replaced it (could probably go longer)
- O'Reilly Super Start (Exide) - Slow turnover after 3 years...preemptively replaced
- Carquest - Slow turnover after 4 years...preemptively replaced
- Honda - Two died after 4 years. One died after 7 years.
- PepBoys Bosch AGM - One lasted 7 years+ before I preemptively replaced it (could probably go longer). Another one stop holding a charge after 2 years and got warrantied.
