Ownership a new battery for a device can be a frustratingly opaque experience. It'south effectively impossible to tell whether more than expensive batteries are actually better batteries. Capacity and fifty-fifty chemistry claims are just words printed on packaging, not something the buyer can evaluate prior to purchase. It's why some people stick to batteries bought straight from the manufacturer, even though they're inevitably much more expensive. And if the problem is bad here, I can merely imagine it'due south worse in China, where product counterfeiting runs rampant.

But with all of that said, please don't bite an iPhone bombardment (or any battery) every bit a way of confirming it'south 18-carat. Co-ordinate to the Taiwan News, the video below was the event of a customer in demand of a new iPhone bombardment biting it to see if information technology'south genuine.

Taiwan News reports 1 Chinese netizen chided the man, maxim: "The battery is non gold, why are you biting information technology?" This is a very good question that almost certainly lacks a satisfactory response. The video appears to be real and neither individual was injured when the bombardment ignited — hopefully the bright flash visible to a higher place serves as a low-cal bulb moment for the man in question.

One popular misconception is that lithium-ion batteries explode when punctured because the lithium inside them has been exposed to air. This is true of lithium-metal batteries, only lithium-ion batteries don't contain enough lithium to have this problem. (This is why lithium-ion bombardment fires tin can exist put out with h2o, while lithium-metal battery fires can't.)

Instead, lithium-ion batteries explode when punctured considering the separator betwixt the anode and the cathode is breached. This separator layer is vital to the function of the battery. Once it's damaged, the bombardment immediately short-circuits, with the results seen above. Bitter a battery can't institute whether it's counterfeit, any more than than licking a CPU can tell you if it's been deliberately mislabeled.

We alive in uncertain times. North Korea's nuclear ambitions, concerns over Russia, Europe'southward refugee crisis, and ongoing civil wars raging in places similar Syrian arab republic and Yemen aren't but United states of america concerns, they're global concerns as well. It's understandable people would be looking for ways to cope. Merely please remember, neither lithium-ion batteries nor Tide Pods are on the approved listing of foods for homo consumption published by anyone, anywhere. Eat a donut. Take a salad. Enjoy a steak. Past all means, drop your lithium-ion batteries off at a recycling bulldoze or dispose of them properly. Just don't effort verifying them with your teeth.
