I wonder how can this be economically viable...
- nickparker 9y agoThis is paraphrased from last time it came up so I apologize for any inaccuracy: They're reject cells from the manufacturing process. In manufacturing you have a specification your products must meet or exceed for you to sell them with a certain rating. Some fraction of the cells a factory produces don't meet that specification, so they're either thrown out or used in unimportant applications like this.
- imaginenore 9y agoIt'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.
- rahimnathwani 9y agoYou 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.
- Dylan16807 9y agoWe're talking about lithium ion batteries. They are all about the same voltage.
- rahimnathwani 9y agoExcept 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.
- Dylan16807 9y agoOh, 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.
