Technician A says that a sulfated battery is less likely to freeze in extreme cold temperatures.Technician B says that a sulfated battery often measures an abnormally high voltage across its terminals immediately after charging.Who is correct?

A) Technician A only
B) Technician B only
C) Both A and B
D) Neither A nor B

Technician B is correct because a sulfated battery, which has lead sulfate crystals built up on its plates, typically shows a false state of charge, leading to an abnormally high voltage reading immediately after charging. Technician A is incorrect because a sulfated battery, due to its reduced ability to hold a charge, is actually more likely to freeze in extreme cold temperatures, not less.
