My Sony DCR-SX63 camera connector pins aren't working.

Although this isn't the right place, I wanted to know if anyone can help me with my Sony DCR-SX63, as I believe these are somewhat similar (at least hopefully). I'm not sure how, but the battery port is not accepting 3rd party batteries and for a while, was not accepting my OEM battery. I was getting an 04:00:00 message saying "Cannot use this battery in this camcorder". For months, maybe years, I was getting that message with my OEM, until I popped it into this cheap 3rd party charger I got today, and it suddenly started working. It is clear that the battery on the camera is not just depleted, I'm currently using a stopwatch and leaving the camera on, and it isn't an issue with the OEM battery, as it lasts a full 5 minutes without just randomly turning off. Sometimes, the message pops up, sometimes it doesn't. With that charger, I also got some 3rd party batteries, and they have worked certain times and not worked. Currently, they are getting either that 04:00:00 error or are just straight up saying they are depleted of battery, even though they are full. I can't even use them on the camera anymore. Does anyone know any way I could address this issue? I tried cleaning the connector pins, but it doesn't seem to work. I worry it is an issue with my camera, but I don't know how I could possibly fix this.
