Greetings,

After extensive research of online reviews, yesterday evening I took the plunge and purchased a new EGO power string trimmer model ST1500SF. After first time use of 25-30 minutes of light trimming I noticed the power indicator light on the battery pack was flashing green continuously. I put the battery back on the charger. The battery pack has been on the charger for over 8 hours and the power indicator won't stop flashing. Is this normal?

Thanks,
Tony

No it is not normal.  There have been several other complaints regarding the same issue.  I think the prescribed solution is to call customer service and they will send you a new battery.  However if you bought the trimmer at Home Depot you should be able to return it for another unit.  Note that Ego's customer service will be closed on Memorial Day.   Sorry your new trimmer has this issue.  Its an awesome trimmer otherwise, and the new battery will fix you right up.

Thanks for the prompt reply and concise advice.  I'm going to Home Depot now to run an errand now and will discuss with them for how they wish handle the situation.  Hopefully they will take care of it by simply swapping a battery.

Be careful and make sure you get the same battery.  The ST1500SF comes with a 2.5 aH battery...if they want to trade it with a 5.0  magnificent, but watch that they don't give you a 2.0.  

Let us know what happens with that, I am curious.  It would make sense to just exchange batteries, but with computerized stock and so forth it might be cheaper for them to just exchange the whole unit.  If they do exchange just the battery, be sure to register the new serial number with Ego.  Good luck!

Thank you for your thoughtful tip.  I was at Home Depot today (05/28/17) and explained my situation.  It was my hope Home Depot would crack open the box of new unit and just swap out the battery.  The sales associate recommended, as you suggested, to exchange the entire unit with a new one... to which I easily complied. 

By the way, the Home Depot in my area only stock 2.0 aH battery which sells for $129.00 while the entire unit (trimmer, charger and battery) sells for $149.00.

Thanks for the reminder of registering the replacement unit.  Done!

Thanks!  The real test will come when I do the yard next week.  I want it to go well because the trimmer itself is awesome.  I will revert with an update next week.

Anyone know what causes the battery to start flashing? What does it mean?

It's a defect in the battery circuitry. If this happens give Ego Customer Service a call and they'll get you fixed up.

My battery isn't under warranty, since I bought it on ebay. But other than the flashing green light, it seems to work just fine.

It's the the 6th or 7th time I use the trimmer since replacing the defective battery which barely gave 30 minutes of trimming time.  I give the trimmer a pretty good workout when I use it.  It takes 45 to 50 minutes to trim the grass around flower, beds, trees, driveway, etc.  I also use the trimmer as a edger by rotating it 180 degree such that the string is perpendicular to the ground to cut a clean well defined edge around of flower beds, shrub beds and driveway.  I haven't yet managed to get power indicator to flash red.  Truly impressed!

I'm having this problem a second time with the ST1502SF. I've already had to exchange the entire unit once this summer. I'm still within the 90-day Home Depot return policy, but if the same thing will continue to happen, I'm not sure it's worth the trouble of trying again.

I ended up just returning mine to Home Depot for a refund before my return window closed. I didn't want to be stuck trying to get replacement batteries every time this happened.

Oh boy, my ST1502SF light started flashing green today. Called CS and a new battery is on its way. Ironically my sons trimmer battery did the same thing two days ago! Both were bought this year and batteries only charged once.

After reading above comments, I'm not going to deal with the hassle of getting my battery replaced.  Going to return it to home depot.

Same problem here with a pair of 2.5 Ah batteries.  Both were used in the ST1502 trimmer as well.  So is the issue with the batteries or is the trimmer somehow ruining the batteries?

When I called customer service I was told that it was a bad battery. It seemed to me that they had dealt with this problem some already. I had registered my equipment on line so she was able to look it all up and got me a replacement battery sent out right away. No fuss, no hassle just good service. I have had no problems with the replacement battery as to this date and have had no problems with the battery that came on the blower that I bought at the same time. Give customer service a chance to help. I hope you have the same experience that I did!

After using my trimmer today the battery started flashing green and won't stop. Putting it on the charger does nothing.

I bought a blower two weeks ago and the battery has the same problem. The battery died after two uses.  I called the Customer Service on Monday (4 days ago!), left a message and never got their response. They said that they will call me back in 24 hours. I am so disappointed!

Battery quality is great and the reason I invested in this line of tools.
Unfortunate you got a bad one or that something happened to it while you had it.  Also unfortunate you had a bad CS experience.
But I have had nothing but good results and the batteries have a 3 year warranty, so I am still still confident in the products.

I was on hold for more that 50 minutes and then pressed 0 to leave call back but then sent to another line with same message and then after ten minutes was able to press 0 and ask for callback. We''l see. Hope they boost their CS department. Heck Sunjoe responded better that these folks.

CS called me back next morning and sent them my receipt. Then no response so I called back. Got a live person who put in order for new battery. Seems they have some CS issues they are working on. Also, problem may be caused by charging battery and then letting it sit at full charge. They said it's better to 1/3 to 1/2 charge it an then store it. Charge it fully just before use. Hopefully, they will better disseminate this information and add a charge indicator to battery so we consumers can follow this procedure more easily and have optimal battery life.

Roger, see my reply to your other post. Ego’s long term storage mode is built into the battery and happens automatically.

Also got replies form other Ego reps to do partial charge for long term storage as described above. In another thread, a user actually tested battery degradation using both methods and active method or partially charging did better than depending on built in storage mode. Still don't know what the fault is that caused blinking light.
