Question

Quizplus · Accepted Answer

Technician B is correct because trickle charging a sulfated battery over an extended period (like 24 hours) is the appropriate method to help restore the battery's capacity. Fast charging a sulfated battery, as Technician A suggests, can cause further damage to the battery and is not recommended.
