You do not need an upgraded battery in your climate. We see lower temps here and the 51R works fine for the K24.
Based on what you describe, you probably have a bad battery. Test and replace as-needed. I do like the AGM batteries- the 51R I recently installed starts my girlfriend's K24 much faster than it has ever started.
