After about 10 minutes of charging my 30 minute charger stops charging and the leftmost of the four lights on the charger is lit with a solid red light.  The other 3 lights on the charger are not lit. I haven't been able to locate any information on what this pattern of lights on the charger means.

1) Is it detecting a problem with the charger and I need to replace the charger (charger is 4 months over the 3 year warranty)
2) Is it detecting a problem with the battery and I need to replace the battery?
3) Is this a problem that I can resolve and I don't need to buy a new charger or battery (wishful thinking)

Thanks in advance for the help.  I tried contacting Ego support but have been hung up on twice while on hold.  I then tried creating a support case through the web site but haven't received any response to that.  I'm hoping that someone here has inside knowledge on the product and knows what the light patterns on the charger mean.

Is the battery charging for the 10 minutes? What do the lights on the battery do?

I know my rapid charger will have a single red light flashing if the battery is too hot, but the fan continues to run. But that happens within a few seconds of putting the battery on it. I believe the charger itself says that a solid red light means battery failure.

In the charger manual (assuming by 30 minute, you mean rapid charger) if the leftmost, LED1, LED is red, the battery is too hot or too cold. It says to allow the battery to warm, or cool, to resume charging. Does the battery seem like it's getting too hot during those 10 minutes? Manual says anything over 135F is too hot. Thinking that this time of year it wouldn't be getting too cold.
Flashing red light is usually an indication of battery or charger failure.

Thanks for the quick replies!  The battery is definitely charging for those 10 minutes as I have been able to get some additional use out of the battery after it has just charged for 10 minutes.  

I typically charge the battery right after I finish cutting either my front yard or back yard (can't do both on one charge) and I alternate doing one each week.  I have never seen this problem over the last 3 years until now; when it occurred about 3 weeks ago and then this past Sunday.  I'll try right now charging the battery when it should be cooler since it hasn't been running in the mower.  

Interesting that google searches on this topic didn't pick up the reference in the battery manual to this problem.  

Thanks again.

The troubleshooting guide in the manual doesn't exactly reference your particular problem. It seems more just about what it means when there's a solid red LED1 and not so much any other details about operation leading up to the error.

Thanks again to all for the help.  I just tried recharging the battery.  This time the charger ran for about 20 minutes and ended normally with all 4 lights lit green.  If I add the 10 minutes it charged before the error plus the 20 minutes it just charged then I get the 30 minutes it should have charged.  
I guess I'll have to try letting the battery cool down before I charge it and see if that resolves the issue.  That is a bit of a PITA since it was much easier to just throw the battery into the charger when I was done cutting.  Now I'll have to remember to charge it or kick myself a week later when I go to cut the lawn and it isn't charged.  

Hopefully this will fix the issue or I'll report back if the problem comes back.  

Thanks again!!!

Jay, your battery shouldn't need to cool down before being able to charge it.  This is abnormal behavior, especially since it just started doing it recently.  Check the vent holes in the battery case and make sure they're not blocked with debris which could keep cooling air from flowing through the battery while charging.

If the cooling slots are not blocked and if it's still under warranty I'd give Ego Customer Service a call and have it replaced.  If the vents are blocked try vacuuming them out and see if the problem persists.

I've had this before. It was due to under voltage. It did not ever recover.


If the battery internal fuse is blown, it will do the same thing but it will not take 10 mins. It takes 30 seconds


Your senario is an odd one. Cooling down isn't required at all as blue said.

Thanks for the additional replies.  After charging it today my battery should be charged enough to cut my front yard this weekend.  I'll see how that goes as well as how it goes to charge the battery after I've let it cool down.  Fingers crossed that I won't have problems though I'm not really that optimistic.  Maybe I can get this battery to limp along for the rest of the cutting season and buy a new one in the spring since the battery is 4 months out of warranty.

I would try contacting Ego now and see if they might honor the warranty due to the short time you are past warranty period.  The longer you wait the less likely chance for success.

Thanks. I have found that most companies are pretty strict about their warranty expiration date. That being said I have an open case with tech support so it is worth a try.  That being said I have never heard back from tech support since I opened the case a few days ago.

Hi Jay! Thank you very much for your post, and our apologies for the trouble you've had. Our database shows that you opened a case with tech support yesterday, so you should be hearing back shortly.

I wanted to follow up on the thread.  I used my mower again this weekend and this time instead of just charging the battery right after mowing I gave the battery a little time to cool down.  I wasn't able to time how long the battery charged but it did complete a charge cycle without stopping with a red light lit on the charger.  So, I'm hopeful that letting the battery cool before charging will let me continue mowing without having to replace the battery for a while longer.   Thanks again for everyone's help.

I should also note that in spite of Amber's comment above I've never heard from the folks at Ego on this.
