Battery Bosch or ODYSSEY
Buy an odyssey. It will pay itself off in the long run nor let you down. I just ordered one for my Rubicon.
I'm running a 320 amp alternator with AGM odyssey battery so far no issues
Bosch batteries in my older bmw lasted around 5 years but I was told it’s recommended to change every 2 years.
Change mine in my 2016 Golf R to this battery and it's been great. EFB shite didn't even last the first 3yrs.
We have a 2009 Fiesta 1.4 petrol and replaced the battery with a Bosch battery 5 years ago after the same issue. The car does a few short journeys a week so not ideal but there's no signs that the battery is about to go flat.
Yuasa are high quality. I generally get Bosch S4 or S5 as they've never let me down.
looking at that reciept seeing Enhanced flooded its even worse, we are a main dealer of Bosch batteries and their EFB rated voltage is 12.6V when not in use not sure for the other big battery brands
New battery fitted and all ok for about 2 months, then same problem. Took new battery out (AGM Bosch S5 A08) and charged it on the bench, left it there overnight. Next morning its reading 12.2v.
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.
