Sounds like your battery has dead cells. It might not pass load test at the dealer. Don't know if your current battery is AGM. AGM batteries are black in color and non AGM ones are white. All the error codes are stored in the vehicle computer and the service advisor will be able to pull it from you key. Mine was a couple pages long.
Remember to trickle charge it if you don't drive it regularly or you will kill the new battery too. AGM batteries are expensive to replace without warranty plus programming fee. We are screwed in terms of paying high price because we live in Alberta.
