My 7.5 amp battery has apparently hit the fan. It came with the 21inch self propelled mower I bought from HD in March of this year. I’ve used the mower all summer with no problems. Also own a leaf blower, carbon fiber shaft edged, and the edger. I have two other 2.5 amp batters that have had no issues since the last year. I have used them all with the rapid charger that came with the mower and this batter. When I put it in the mower it mows for 2 seconds and then quits with an alternating green/amber or orange blinking. When I put it on the charger it blinks 25% forever and never moves past that and when I press the button on the battery it doesn’t light up at all. Any suggestions? Could I technically take the whole unit back to HD since I purchased it on their credit card and have them replace the whole system even though i don’t have the box or should I just call Ego and have the battery replaced. Tried calling today, but was on hold for like two hours and eventually just hung up. Any other suggestions? Yes I have tried and succeeded in charging the smaller batters in the rapid charger so pretty sure it’s not the charger. Also, when I put the battery on the smaller charger that came with weed eater it just has a ticking sound and a flashing green light on that charger.
