Corolla quest battery reap off at the dealership

Bought my Corolla quest 2016. Year later the battery wasn't performing well, I bought a new battery at the dealership Mcathy Bruma, 2018 mid Year the battery couldn't perform. Corolla quest battery is too small for the car and we reaped off time again. I recent went to the dealer again I was told they can't find the info of exchange.. Seriously.
