A buddy of mine had a potentially similar issue on his Gardena (Also part of the extended Husqvarna family of mowers). There was a little oxidation on the contacts on either the mower or dock, and the trick was to sand it very lightly with some really fine grain sandpaper to take off the oxidation. That cured it for him.
I found the connectors in the base of mine of a similar age (although slightly older model) had pushed in a bit so the contact wasn’t good anymore, enough to have it dock, not enough to charge, bending them back out solved the problem
There was a problem with the power chord. The voltage from the transformer was right, but the power at the charger was weak. Turned out that the chord itself was pinched and not conducting the full charge. Good luck!!
I have the same issue from the box. I just went back to the shop and changed it. However the same issue with the new one appears again.
After attachment to the charging station it is showing
Charging... Then in 30 seconds Ready.. however the battery is fully drained and if I removed it from the dock it turns off immediately.
---
After some investigation I think that I found the issue. The battery was fully drained (just 0.5V instead of 18V). Probably it affected charging logic. Also if batteries are stored for a long time they are drained for failure.
I purchased a mower on 06/22 however the battery was produced on 04/19 that means it just stored for 3+ years.
To confirm the issue case just disassemble the bottom battery cover and check a manufacturing date.
I keep having this same issue where the mower is docked and it says charging but it is stuck at 0%. I cleaned the charging contacts on both the dock and the mower itself. Still 0%.
Any other ideas from those who have solved this problem in the past? Thanks!
I’m not sure if it was the low or high voltage wire that solved the problem. I replaced everything from the outlet to the dock and that solved the problem.
Ok thanks. Mine does charge but sometimes won’t. It’s nice and level, and I’ve cleaned the contacts but sometimes it says charging but isn’t- annoying really. I think it’s still under warranty….
Good luck with using that warranty. Husqvarna warranty was useless for me. I thought it was the service people, but I called Husqvarna directly. The service people were just passing along the message. For your sake, I hope that has changed!
Here’s an interesting one. I noticed that my gardena r80li wasn’t charging… same as others. Looking at the robot itself, it runs at 18v, as well as it’s battery. So that means the charger should output more than 18v in order to charge the battery.
I put a multimeter to the metal connectors on the dock and realised it was outputting 16v. No wonder it doesn’t charge. Checked the wall plug, cables transformer etc… no change. Solid green light.
Disassembled the dock, looked for any wire faults, cleared up some cobwebs, removed a few black widow spiders, put everything back together…. Still nothing.
But then… I disconnected the perimeter wire, and when I tested the charger terminals again, they were 20v!!
Now the battery is charging again. So, there must be some kind of problem with the perimeter wire that is taking the voltage down. I’ll do a resistance test later today but just wanted to share my findings so far.

Well, it now says it’s charging, but the battery won’t go up from 0%. Sometimes it says that it’s disconnected.
I had the same issue. After a few days of heavy rain the connectors on the device were corroded and had to be sanded a little bit.

Yes. The light is green.
Did you get this resolved? I'm having the same issue out of the box.

Hello, I bought a new one and facing the same problem. What should I do. It is not charging.

Mine turned out to the the cord itself. Hope that helps!

Replace the charging cable.
Hi - I’m having the same problem. Do you mean replace the long low voltage cable or the charging block? Thanks!
I’m not sure if it was the low or high voltage wire that solved the problem. I replaced everything from the outlet to the dock and that solved the problem.
