Not sure what type of battery charger you used, but mine is a 10 amp Twin Rate charger. It has switch settings for LOW MAINTENANCE & MAINTENANCE FREE battery types, along with a MANUAL setting. I've never experienced the "boiling over" situation you described above with any car battery I've charged with this unit.
Typically, once the correct battery type is selected, the charger will start out around 5 amps (as most batteries aren't completed depleted when connected) and gradually reduces to 0 amps and shuts off automatically when the battery is fully charged. So I think it would have to be really a bizarre circumstance for a car battery charged with my charger to experience the "boiling over" that happened to yours. Maybe I've been lucky all these years.
But thanks for the "heads up" and I'll pay particular attention on the XFire when using the battery charger in the future.
