Trying to make household appliances last longer, to keep their plastic in active use and out of landfills. So when my old cordless phone’s battery wore out, I ordered one from an eBay vendor. Cheaper that way. (I care about low cost, too, to a point.)
Of course, the product did come with a small plastic blister; I assume there’s some plastic in the battery itself, but that was a given and the packing isn’t.
Note: I received no compensation for this notice; indeed, I have not contacted the vendor about it.
