~8 yrs ago i bought what I thought was a genuine Dewalt 18v Li battery, it died after 6mo, when I brought it to the Dewalt store they were able to show me the very subtle but distinct differences between the fake I had and a real one.

So far in 20yrs of use I've had 1 Ryobi 40v die and that was a refurbished one that I got by accident, currently have 3 genuine ones that are on the way out, all from, 8 to 10 yrs old

I have had some Milwaukee M12 batteries die (usable life was VERY short, but still worked). I bought, what I believe is a genuine M12. If it's fake, it's VERY well done, battery, packaging, etc..., and the price wasn't "too good to be true".
