Arlo Pro installed but doesn't take charge anymore. Are my batteries reaching the end of their life?

[Boxerdog]

My Arlo Pros were installed just over three years ago.  Several are not taking a charge anymore when I try to recharge them.  I live in Florida where it can get hot. Question: Are my batteries reaching the end of their life?

Maybe... li-ion battery pack can be from 100 charge cycles +....

tho I do have several over 3 yrs that are still fine.

make sure yr using the proper adapters for the cameras and also read the added info.
