Yeesh. This is written as if someone is just discovering rudimentary details of technology, manufacturing, and logistics. But instead of learning, they're repeating benign information in the most paranoid-judgmental way possible. "<i>Amazon ... would not explain why tracking is assigned only after a product has left a fulfillment center</i>". heh.<p>These batteries are made by Fujitsu? That seems quite upstanding compared to what I would guess. It sounds like there is/was a quality problem, but no actual details to put it in context. I don't know Fujitsu's precise reputation here, but it's possible Amazon could have switched to them <i>due to</i> quality issues somewhere else.<p>Shedding some light on supply chains is certainly a worthy goal, but this does not help.
While mildly interesting - take any mundane product - a can of beans on the shelf at the grocery store - white label manufactured in a plant in the Midwest, ingredients from around the world, a can made in Mexico with metals mined in China, with a label printed in Florida from paper paper mill in Georgia from trees in South Carolina
I actually have a little more trust in AmazonBasics batteries than others.<p>I once bought a AmazonBasics power bank which got recalled quite some time later due to a possible fire hazard. They refunded me the money and told me to dispose of the unit. Although the fire hazard part did not help my trust in the brand at first I later wondered how other manufacturers would have handled this. I'm pretty sure that I wouldn't have heard anything from most of them.<p>(Lightly related, just this week I noticed the battery of my Dell laptop had swollen so far that it bulged the casing. Batteries are scary...)
