It's 3£, which is $3.88. For a 600mAh battery. You can buy an 8-pack of 2800mAh batteries (each) for $15 on Amazon. So the manufacturer is definitely making money.
The recycling part is potentially interesting. Whoever figures out how to get a ton of these discarded can make money by making power packs.
Except the comment to which I replied was talking about '8-pack of 2800mAh' from Amazon. I'm pretty sure they're talking about 1.5v Ni-MH AA batteries.
