Battery Panasonic or Bosch

I use a Group 27 battery in my Mustang and have found Bosch to work very well for me.

Panasonic Eneloops for me all the way. Bit of an initial investment, but they work so well they're all I buy now for anything that needs batteries. They even kept my Pix running for almost 10 days!

We had a 2016 lexus with original Panasonic battery. in 2022 had to be replaced, thats 6years. In Arizona batteries last about 2 years. so that was nice.

Put a new Bosch AGM in.

Probably the easiest car to swap a battery on imo. Just remove and replace, negative off first. Bosch is good quality, but not required...Use 80Ah 12V.

I am using Bosch battery for my BMW, going through my 2nd, it lasts for 2 years+, less than 50% of the price of the dealership

There is a known random issue with 400 packs. On mine, it is always when I turn on the bike. The speedometer doesn't come on and there is no assist. What I learned about on the internet is to push the test button on the battery with the bike turned on and it will reset and work just fine.

I find that the Bosch batteries I regularly sell last 5-7 years or 5-7 months.

My experience: Stay away from Bosch.

I've had a couple of issues with my BMW 5-series, I found Bosch batteries don't last as long as they should. I changed them twice in the span of 3 years or so, each time resetting the battery management system with the correct capacity. I changed it to a Deka Intimidator and I'm much happier with it.
