I have a 2.5ah battery with a mfr date of 2/17. Was functional until a couple weeks ago. Finished some light weed trimming with the tool it came with, put it back up for storage and the battery light continuously blinked green for over 24 hours. Now it's a brick. Ego said they'd send me a new one once I provide the receipt... well that's long gone. I'm positive I bought it at HD summer of 17, they couldn't pull anything passed 2 years ago. Am I screwed here?
