Doorbell Not Working with Fully Charged Battery

Hi. I had a Video Doorbell 3+ (plus spare battery) from Feb 2021 which was replaced by a Video Doorbell 4 in Feb 2022. So I've now got 3 batteries that I've been alternating between. The battery needed replacing today - the newer battery was in the doorbell and both of the older batteries were fully charged (green light only when connected to a charger). But when I put either of the fully charged batteries back in the doorbell it didn't recognise either of them - no flashing blue lights as it normally does, and no response even when I held down the reset button for 30+ seconds on either battery. Is there a short lifespan for the batteries if they've been charged quite regularly? I'm usually lucky to get a months use out of a fully charged battery so they get charged quite often. (The newer battery is currently on charge so I'm not able to check it again with that one yet.) Thanks.
