Quizplus · Accepted Answer

Technician A is correct in stating that AGM batteries never require water, but incorrect about the spiral wound plates, which are a characteristic of some, but not all, AGM batteries. Technician B is correct about recombinant batteries, which include AGM and gel-type batteries, using a process to recombine hydrogen and oxygen back into water, thus not requiring water to be added.
