https://community.arlo.com/t5/Arlo-Pro-4/Pro-4-XL-two-batteries-read-97/m-p/1905943#M8402 <P>Installed a set of three Pro 4 XL cameras in February. They seem to be operating fine, but I have a concern about 2 of the 3 batteries. After charging them yesterday, one battery read 100% immediately after being installed in the camera, but the other two read only 97%. This may seem trivial, but the cameras are at a property that will be uninhabited for weeks/months at a time and is far away from home, so I'm wanting maximum capacity from the batteries. Any explanation why the two batteries didn't read 100% right out of the charger (yes, the light on the charger had turned green)? Is there a potential defect?</P> Wed, 15 Mar 2023 22:18:12 GMT ekclymer 2023-03-15T22:18:12Z https://community.arlo.com/t5/Arlo-Pro-4/Pro-4-XL-two-batteries-read-97/m-p/1905943#M8402 <P>Installed a set of three Pro 4 XL cameras in February.

It's based on measurements of the battery voltage and perhaps the current draw.</P> <P>&nbsp;</P> <P>You'll need to run them for quite a bit longer to get a good estimate on how long they will run between charges.</P> Tue, 14 Mar 2023 20:29:07 GMT https://community.arlo.com/t5/Arlo-Pro-4/Pro-4-XL-two-batteries-read-97/m-p/1905957#M8404 StephenB 2023-03-14T20:29:07Z
