Slight follow up to a previous post of mine, I found the ever elusive car key, but I now have a dead battery that has refused to be jumped in my first attempt. While i will try a few more times before I give up, I figured I'd ask here; what do you guys suggest for a new battery.
O'Rielly's gives me these choices. How does one pick a car battery from that wide range of prices, and are there ones you guys recommend?

Much appreciated!!

 

Am using the Walmart MAXX sized to fit. Here (https://www.walmart.com/ip/EverStart...0&from=/search)...

Autozone Duralast got 5 years + out of my old one , use the protective terminal covers that comes with the battery to give a cleaner look

 

I use AMG from Wallmart but it is a personal choice. I would contact the Mercedese swap shop for a spare key before something happens again.

 

There is a search box on this site, but here are some additional answers from members:

The DieHard Platinum AGM is my choice.

 

We bought the car, drove to a hotel planning to drive home in the morning. Dead battery.
Called AAA. The tech was very thorough, tested all electrical systems before installing the new batter, then repeated all the tests.
The engince needs a lot of juice to crank over, our old battery was putting out 12 volts instead of the what? 700 it needs?
The battery comes with a three year warrantee, so, if it dies in two and a half years, new battery.

 

My choice for 16 years with the Crossfires has always been INTERSTATE BATTERIES

 

Remember weight means more lead in it and it is the lead that makes it more powerful, lightweight batteries have less power.
People on here have purchased lightweight batteries and soon found out that they are not reliable. These cars needs powerful battery and a lightweight one is no good.
The OEM battery (Varta) was the best battery I have had. Allstate is made by the same international company (Johnson Controls) as the OEM ones.

 

Project Farm did a great battery test/review on YouTube. I bought a Walmart brand battery after watching his video

 

It's luck of the draw these days with car batteries. Some people call Walmart batteries "Neverstart"

The original Varta battery was magical until it started to crack around the negative battery terminal.

 

Not Crossfire related but just this past weekend, the Group 58 Super Start Premium battery (2-Yr Replacement Warranty) in my 1995 Jeep Wrangler Rio Grande failed. Per my battery tester it showed just barely over 8 volts & tester said to replace it. I bought this battery from nearby O'Reilly's Auto Parts store. Bought the battery back in SEP/2021, so it was covered under full replacement warranty of 2 years. Took it back up to O'Reilly's store, they tested the battery & confirmed the low voltage (same value my tester showed), pulled a replacement battery from rack & apologized for the poor battery life. I left with a new battery at no cost. In all the years I've been driving & replacing batteries in the various cars I've owned, this was the first time I've ever replaced a defective car battery under warranty. (Note: The replacement battery is covered by the original warranty period so I've only got another 4 months of full replacement warranty on the new battery. Retailers don't ever want to have to replace more than 1 battery under warranty!)

 

The original VARTA battery in my 2007 Coupe lasted 8+ years! Replaced it with a Duracell battery in MAR2016 (+5.5 years life). Replaced that battery with a Super Start Extreme battery (3-Yr Replacement Warranty) in NOV/2021. Thus far, only 3 car batteries used in my 2007 Coupe.

 

I got my 2005 with the Varta in it in 2011, I thought I had better replace it after two years. It had never faltered once, I kept it charged for three more years. I replaced it with a top of the line lead/acid CTC battery, it failed in two years. With the remaining warranty I upgraded to a AGM battery, it hiccuped once after less than five years so I replaced it with another of its kind. The existing one has done three years thereabouts. You can never tell with batteries one minute they are great and then suddenly fail. Four years is about the most you can rely on them, less if used daily in cold climates. I keep my car in a garage that rarely goes below 3 deg.C. During its hibernation period. I still have only taken it around the block this year.
