Put in an OEM battery on my 2015 C7 convertible stingray in January 2021. I do not drive my car that often sometimes as little as 30-40 miles in a week. After getting my new battery I experienced a few weeks later where the car would not start and used one of the little jump starters to get it working again and since then I started keeping it on the OEM trickle charger. Yesterday my car started fine- I drove it about 30 miles and it had been on the trickle charger, when I got into my car after it sat for two hours it would not start I had to jump it and then I drove it 15 miles it started fine. Even though I don't drive my car a lot it seems like my old battery never had this level of issue when I was driving it the same amount of time. So obviously I can take it to a dealer but I'm just curious if anyone has any advice and thank you. I couldn't find a different place to post this thread so I hope it's OK.
