Battery Bosch or Deka

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.

I really like the Deka ETX12. Point is these batteries are bulletproof. They last longer than any other battery I have ever gotten. I highly recommend them.

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.

I currently run a Deka Intimidator in my rig and it's been problem free for 3 years now

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'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.
