Battery Jumps to 100% When Plugged In: Acer Aspire Issue

I recently purchased an Acer Aspire laptop for my business, 350 PPM Ltd. I've noticed that when I plug in the charger, the battery percentage jumps directly to 100%, regardless of its actual charge level. It doesn't seem to be charging normally, and I'm concerned there might be an issue with the battery or charging system. Has anyone experienced this before or know how to resolve it?"
