Battery Bosch or Deka
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
Deka ETX15, Deka makes a great battery and they’re sold under a few manufacturers.
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.
I use Deka for all of my cars and they take Minnesota winters like a champ
Deka is the best I’ve found.
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 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.
