Ego 56v battery problems

Hi. My 56v battery has been failing frequently in the last few months. It stops working in the mower and rapidly flashes yellow. Usually, I can then put it in the trimmer and it works again. But now flashes in the trimmer too. If I press the battery button, it also flashes yellow. In the charger, the charging light flashes green, while the battery light cycles through red, yellow and green. Anyone know what is wrong?

I had this happen to one of my batteries a couple of years ago. My personal guess is a faulty temperature sensor, but that’s not confirmed.

You’ll need to call Ego Customer Service and they’ll get you fixed up.

Can you let us know what mower and trimmer you have? Might be helpful.
The green light on the charger and the cycling lights on the battery during charging are exactly what is supposed to happen when charging a battery.

You should call C/S if under warranty, but sounds like could be a heat sensor but from my experience I would say it has a bad cell in it which would cause a rapid depletion based on the strain of the battery. ex.. mower will have a bigger draw than ur trimmer. since it works in both pieces of equipment and it takes a full charge, my guess battery vs sensor. not sure how many cells are in the battery but once one goes bad it will affect the rest. like a car battery

Sounds like a bad battery. Mine flashes green also.Sometimes doesn't charge at first. Mine is still useful but always flashes green. So the beeing that the green light is flashing green in or out of charger drains the battery down. Call customer service they will ask for serial number. and manufacturers date.

Patrick, the green, orange, red flashing light in the charger is normal charging behavior. Wait, is Best Buy offering EGO products now?

Ok thank you my other battery didn't do that.

If your other battery was mostly charged, meaning over 75% charge, the charger won't charge it so you wouldn't see those colors. 
Ensure that other battery is run down sufficiently to initiate a charge sequence then see if flashes the colors when on the charger. If it doesn't happen then, you have a bad battery (and not the one you thought after all).

Do these batteries eventually need to be replaced? If so, what kind of life should I expect?

Yes, all batteries have a life span.  Ego is a newer product so there is not a ton of longevity data.  There are batteries out there now passing the 5 year mark in usage.

Opinions vary, but I am expecting 7-10 years from mine.  Use, charging practices and storage conditions will all affect the life of the battery.  They come with a 3 year warranty so you are guaranteed at least that long.

My battery seems to be running down more quickly lately. I used to get my whole front OR back yard done in one charge, even did both once! Lately, it seems to run down before I finish. Mower and battery are about three years old now I think.
what battery are you using? im just curious

if you are within the 3 year warranty and can show a substantial drop in power, Ego will replace the battery.  Others have posted about just such a problem and replacement by Ego.
A nominal drop in power is normal for batteries over their life.
