Sorry for your misfortune, hopefully others can learn from it. There are a lot of threads here about " i changed my battery and did not register it, and it works fine". Unfortunately you got stung and learned first hand what can happen when a battery is not charged properly. Registering the battery is about telling the charger what kind of battery is installed (wet, AGM,etc), and what stage of life the battery is in so that overcharging does not occur.
