#105 is getting an new (refurbished) battery next week. It went the the SC this week unable to charge with a battery service required error. Not sure how I feel about it yet but they are replacing my 139CAC battery with a 146CAC battery. I don't know a ton about the batteries but it seems my CAC is always lower in winter and I haven't balanced it in a while. The new battery is coming from CA. Should I be concerned that the new battery from CA might not be a true equivalent?
