18883RE: [RoboMower] Batteries not charging
- Jul 17, 2014
Mine did the same thing years ago, and I simply quit charging in the battery inside the mower. I use an external fast charger now and rotate two battery packs. I assume my issue was charging circuit related internally, as my display still works and everything else seems fine. May not be worth the effort if you can get an external charger still….
The yellow cable in the cradle is the first place to look as it flexes back and forth everytime that controller is removed or the charger is attached to the port it's on.
Check the connection of the controller for corrosion. I've had the same problem with the RL1000. The controller board that the controller hooks into really isn't that expensive. I think 16 bucks when I bought it.
While the controller looks like it has an RJ11 phone jack, it doesn't. It's an odd sized plug that is now obsolete. From the female plug, I determined this. I'm now in the process of replacing the jack and don't know yet if the standard telephone crimper will work on it. But, the next logical step is to look for and remove any corrosion on the plug and jack.
I checked the yellow cord. I couldn't see any damage done to it. During the process of checking it, I noticed that the display screen is completely blank (and the charger is still hooked up). It is not responding to any control buttons.
Check the (yellow?) cable that runs from the handset cradle to the mower. My RL850 did the same when that cable was defective.

Subject: [RoboMower] Batteries not charging
Hello everyone. I haven't posted on this group for a long time. My RL550 was purchased around 2004 and its still going strong. Well, until now. Maybe someone can help me out with this problem.
The batteries are not taking a charge. The screen display shows that it is charging, but then will either beep at me or will display the message "check power." I have plugged another device into my power outlet and it works fine. It doesn't matter how long I leave it on the charger, it just isn't charging.
I'm assuming that my battery charger has failed. Would there me anything else that could cause the problem?
