Reason for my ego battery failure determined. I resolved the problem!

The 4 Ah battery quit and was flashing red and then off. According to what I read on posts, it was remotely possible that the battery overheated even though it was a cool day and I was not using the leaf blower on the turbo setting until it "failed" and shut off the blower. It would not charge, flashed red and then showed a full charge. The next day, I put it in the refridgerator for 2 hours at 34 degrees F. Then it charged normally to a full charge and the "malfunction" disappeared. The battery is a little over 3 years old and I have always kept it fully charged, take it off the charger when charged and placed it on a shelf in the basement. It appears that I just saved between $206 and $239 for a new battery! I hope this will help someone else with the same problem. I will update this post if the battery fails again.

Thanks for the post, Garry! Yes, it seems some batteries may fall victim to failed temperature sensors, in which case refrigeration can bring them back.

Thank you Gary..  I may have the same problem with my 7.5 ah lawn mower battery.  (2 months old). So I just ut it ion the freezer.  Hopefully a couple of hours will reset the temp sensor..  Since it doesn't charge now, ( it stays at 25pct when on the charger).  a try can't hurt.

I solved my problem with my three batteries not lasting more than a few minutes each, I took the blower and three batteries and threw them in the garbage and bought a gas powered one

It seems like using the warranty might be the smarter way to go. Or figure out what you're doing to keep trashing batteries. But maybe thinking things through isn't one of your strengths.

Ticky Tocky, you need more patents, EGO now has batterys with undated technology. Trashing then may have been to soon.
very interesting, thanks for the post and update

I am going to try this.  The rapid charger says my battery is 100%, but it runs only 10 or 15 seconds before dying, and the lights on both my mower and battery begin to flash red.  If I remove the battery and reinsert it, the mower runs a few seconds but conks out again with the same flashing lights.  Granted, my mower is probably four or five years old, but I really don't like the idea of paying another $350 to replace the 7.5Ah battery.  Subtract the price of the battery from the self-propelled mower, and it's like the mower only costs $150. :(
