Battery Bosch or OEM Hyundai

Change the battery to a bosch one, I had this issue and my car does 600 miles a week for work took it to toyota and they just kept charging it then giving it back to die again the next Monday morning, they tried to say I wasn't driving it enough until they pulled up the service history (2020 with 54k miles) but they still wouldn't agree to replacing the battery

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

Put a new Bosch AGM in.

Original battery in my GF’s Elantra finally died today after 10 years.

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.

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.

I bought a Bosch battery from a respected online company in the UK. The only change I made was uprating from a 100Ah Varta I think the original was to a 110Ah Bosch S5 015 as I thought more storage would help as the car ages and things are naturally a bit more susceptible to failure. Battery lasted 3 years until about January/Feb 2024 when a cold snap hit and the battery just failed to hold a charge overnight.
