Very Slow Battery Charging

[JoeWar]

I have several Arlo 4 cameras and 5 battery packs.  I use a 2-port charger as needed.

Recently, I experience a quite long time to fully charge a battery pack.  Like 24 hours or more, even when charging just one battery, not two.

This is much worse than in the past.  Is it possible that the battery packs degrade over time, as to how long charging takes?  Or, might other things be a factor?

It could be a failing charger.  Is this happening with every battery, or just some?
