Batteries not charging

I have had to put my rov project on hold so to programming issues and decided to charge my batteries after a few months of them sitting on my desk. I set them to charge and start task. I get beeps and I’m asked battery type LiHv. I confirm and nothing happens. I try the other option and abnormal battery connection. I try the CB other battery and the charger tells me abnormal balancer port connection. Is there anything I can do to mediate this or am I just out of two batteries?

Update. One battery has began to charge but the balancer port error battery is still showing that error on a different charger.
