Pardon the crude image. These are 12 volt, 7.2 Ah batteries, all the same make, and model. They’re from a server backup. Can, or should, I charge them like this or would it be safer or more power efficient to charge them individually? I was hoping to charge them like this to save time. In one of my prevous questions (on a different topic) someone told me to charge them either individually or in groups no more than 3.
Thanks for any thoughts.
