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.



You can only compare capacity in mAh if the batteries you're comparing have the same voltage. If not, you need to convert to mWh.

A 600mAh 3.7V battery holds the same amount of energy as a 1500mAh 1.5V battery.


We're talking about lithium ion batteries. They are all about the same voltage.


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.


Oh, maybe I shouldn't have given them the benefit of the doubt. Why would they talk about incompatible batteries? Weird.

You can get a four pack of 2800mAh lithium ion batteries for that price, though.
