My dealer was nice enough to do a free battery check. Apparently, they said that the voltage was not the main factor as the reading should be above 12V (mine was 12.39V). Rather, they said the key is CCA, a full battery is 800 and mine is 463, so just over 50%.

How long would you guys wait before getting a new battery given these readings?
