I'm new to the forum, and new to e-bikes, so thanks in advance for humouring me ...
Last November (2020) I bought a Daymak e-bike online from costco.ca here in Toronto. It's this one: https://www.daymak.com/milan
When I unpacked it I saw a label on the battery that looks like it might be a date stamp. A pic is attached. To my untrained eyes it looks like "DE 2009" may refer to the date the battery was manufactured. If this is correct then the battery is more than eleven years old. (There's a bunch of other text on the label but I can't decipher what it means)
I raised this issue with Costco who told me that Daytek insists the battery was manufactured in 2019, not 2009. Who/what should I believe?
(I understand that a Lithium-Ion battery like this one will lose significant charging capacity over the years even if it isn't used. Am I right about that?)
