My experience is that if a battery is called "genuine", you have
to check very carefully to see that it is also described as
"new"/"unused" (which it is probably not).

Batteries from another (random) supplier have since lasted well,
so far.

Same here. I think I get better odds of a good outcome by buying
a random supplier's "matching" battery, than of getting an actual
unused genuine one. Also, if the device is really old, it seems
to me that any actual unused genuine battery may have suffered
from aging.

I have interesting problems sometimes buying electronic accessories for
a keen price.

A set of active 3D glasses for a Sony TV can cost a lot in a dealer
(£100 a pair then), and is available discounted across both Amazon and
eBay. On there some of the packaging, printing and pack photographs look
suspect - never mind their claims that this a genuine or a genuine
compatible with an original part, either will leave my head spinning.

So I deliberately wound up buying something cheaper that looked
completely not a Sony product, yet had some positive views from previous
purchasers. It was fine for the two 3D bluerays I own.
