Battery Bosch or OEM Hyundai

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.

And yet my 2008 VW had a Bosch battery out the factory ????‍♂️.

Fucking thing lasted 10 years or so though. So credit to Bosch for that one!

I've had good luck with Bosch (made by Varta iirc) and Yuasa.

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.

I switched to Bosch after that. that failed after 2.5 years, just under warranty. so it can happen with any company. some batches might have good quality some do not.

My experience: Stay away from Bosch.
