2018 Mazda 6 is going fine.\n\nProbably due for a battery soon as preventative maintenance.
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.
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
At one time Bosch batteries had a terrible reputation but they now have their quality control back on track.
My 2014 CX-5 eats batteries and always has since i bought it brand new. I usually have to replace 1x a year\u2026 and I know it\u2019s coming about 45 days in advance because my bluetooth and USB chargers will suddenly stop working and that\u2019s how i know oh my battery will die soon!
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.
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.
