Question

Rochelle Ricketts · Accepted Answer

Final Answer : A, Explanation :  Technician A is correct because gassing in wet cell batteries indeed produces a potentially explosive mixture of hydrogen and oxygen, especially during charging cycles. Technician B is incorrect because gassing can occur during both charging and discharging cycles, not only during discharge cycles, and it is not exclusive to maintenance-free batteries.
