Arlo Camera Ultra 2 not charging

[MikeFM]

I have 4 Arlo Ultra 2 cameras. They are roughly 3 years old. For the past few months 2 of them won't charge. The light comes on to say it's charging but it's not charging.

I've replaced the batteries thinking that was the problem. 

I've tried different USB power packs thinking the Arlo ones provided were faulty. 

I've tried different power points.

I've tried swopping the cables etc.

I've taken the batteries out and re-inserted many times.

Nothing seems to work.

Has anyone had similar issues.

You say "the light comes on" - it should only blink blue briefly to indicate power has been applied. Is that what happens or is it on all the time?

Have you cleaned the contacts on the camera and cable with isopropyl alcohol to see if that helps? Make sure the camera is fully seated into the case (the camera face should be flush with the case). If that doesn't work, the external charging station and an extra battery may be your best solution so you can just swap batteries as needed.

BTW, did you let the batteries fully deplete before charging? If so, don't do that - charge proactively. You can try this procedure to see if you can get the batteries charging - the key is to plug in and unplug many times to get enough charge into the batteries to allow them to then charge normally:

Thanks for the feedback.

Yes the blue light comes on only briefly. Flashes a few times then is gone. My assumption was that this shows that the battery is charging. But of course this doesn't happen.

I haven't tried cleaning with alcohol. so I'll try that next. But I'm not holding my breath as this should not be an issue with brand new batteries as I have also tried.

The old batteries did deplete all the way down as I kept using the system even though I couldn't get the cameras to charge. However the new batteries were both above 50% when I tried to charge them with no success.

 This depends on how the LED behavior is set up in the app.

If the battery no longer powers the camera, then the LED will flash when you connect the power.  That is because the camera is booting up and reconnecting to the base.  The LED then turns back off (whether it reconnects or not).

Normally the LED will come back on when the camera is fully charged.  But that is something you can turn off in the camera settings.  (If the camera is always AC powered, then this setting lets you keep the LED off).

Have you tried swapping batteries with the two working cameras?
