Had bought one from Costco. The battery started giving the red blinking light issue in a little over a year. Had to buy a new battery because of this. I don't trust this brand for this specific reason. I have tools from practically all other brands including refurbished 40v ryobi and I haven't had this problem elsewhere.

What blinking red light issue? Is not the battery just getting drained? Sorry if it's a dumb question, but I'm just getting into these things

Eh, batteries do fail.
Did you contact them? They have a 3 year warranty.
I have 2 of their batteries (a 2Ah and a 4Ah), very old (6+ years), still going strong - used them in the snow blower the other day.

Did they honor the warranty?

I've had 4 total 80v batts - one battery failed even though I kept a good charge on it over a winter. I called Green Works and they replaced it.

DJI drone batteries usually deplete to 75% for storage if they haven't been used in two weeks, so I tried to keep these charged up and if I don't use them, I'll rotate them on the charger about every month

Sounds like the battery was too hot to charge. It happens, it's why I have 3 (or maybe 4 now) in rotation. Spring lawn season and summer heat really puts a lot of load on these batteries and they need to cool prior to charging.

"I'm having the same problem. While charging, I get a blinking red light, and it looks like the battery failed after only a year."

Where are you getting a tool and 4ah battery for this price?

Edit: dang, I am seeing some expired deals that were close to this price with 4Ah. I don't need anymore of these damn tools though lol
