Battery Bosch or Duralast

The battery in my MB was the original Bosch so 20 years old when I replaced it.

(for general reference Lion are one of the worst battery brands out there. Exide are OK but that's far too expensive. Bosch and Varta are generally the exact same product with different stickers on and are always good, and rarely all that expensive.

You need this one, and it takes about 10 minutes to install. Just hop into the front trunk, unbolt the bar from the firewall that braces the battery -- iirc 13mm. Remove the tire inflator and the box (pulls right out), remove the other bolt, unscrew the two terminals (10mm probably), swap batteries. Done.

These parts are New. Battery duralast gold

I will second a class 3 Bosch. I have one in a hilly city that absolutely rocks the steeps and has a great battery life. Going on 2 years strong and I've had zero battery issues. It rains a lot here but no problems with the Shimano drivetrain either, just regular maintenance.

Duralast AGM. No leaking, minimal to no corrosion, god life, decent power, and most importantly it was readily available.

Just had a 5yo Napa battery die, put a new Duralast Platinum Elite in there, back to running normal except 2 things: 1/ Random engine fan activation seems to be what killed the previous battery. Still happening.

Drive a 2018 Nissan Rogue, about 80k miles. Have a Duralast Gold battery from Oct 2023, but live in central Texas where I hear batteries don't last as long.

Duralast is almost always johnson controls, made in mexico.

Last December, the OEM battery died and I replaced it with a new Duralast battery from AutoZone. Fast forward to today, the car wouldn\u2019t start at all. Had to jump it just to get it running and drove straight to AutoZone to get it tested.\n\nBattery tested good. Starter tested good.\nBut the alternator failed, specifically the charging current test.
