Battery warranty sticker

[DickB]

This letter from the FTC in 2018 is interesting: https://www.ftc.gov/news-events/press-releases/2018/04/ftc-staff-warns-companies-it-illegal-condition-warranty-coverage
"Each company used different language, but here are examples of questionable provisions:
This warranty does not apply if this product . . .  has had the warranty seal on the [product] altered, defaced, or removed."

I've worked in the IT industry for decades.  This has been true on PC - related equipment for a long time.  No one in the 1960s was even allowed to look sideways at an IBM mainframe!  I had a SUN Systems server in the '90s that was the same.

Especially on electronic equipment, manufacturers loved to put those holographic stickers on everything.  Just like Microsoft has done for YEARS & Years!  It is a standard SOP anymore.
