Carbon dating doesn t work
It takes another 5,730 for half of the remainder to decay, and then another 5,730 for half of what's left then to decay and so on.The period of time that it takes for half of a sample to decay is called a "half-life." Radiocarbon oxidizes (that is, it combines with oxygen) and enters the biosphere through natural processes like breathing and eating.There are two distinguishing features of alkalines: First is their long shelf lifethey've still got plenty of energy even after sitting around for seven years (vs.rechargeable batteries, which lose their charge much faster), and that they're prone to leaking. This is how carbon dating works: Carbon is a naturally abundant element found in the atmosphere, in the earth, in the oceans, and in every living creature.C-12 is by far the most common isotope, while only about one in a trillion carbon atoms is C-14.That's not too much of a problem, because there's not much difference in capacity from brand to brand (as long as you're comparing standard to standard, and high drain to high drain).They're all pretty much the same, despite the manufacturers' commercials.
Radiocarbon dating has transformed our understanding of the past 50,000 years.
There is a constant exchange of carbon between the biotic and the abiotic world, thus forming a cycle which is called the carbon cycle.
This cycle plays an important role in maintaining proper levels of carbon in the Earth's atmosphere.
Consumer Reports found that the spread between the best and worst alkalines was only 9-15%. Alkalines leak more frequently than any other kind of battery. Three of the biggest battery-makers offer to replace any equipment damaged by their batteries.
Tests by ZBattery also showed little difference between name-brand alkalines. The Rayovac and Energizer guarantees seem to cover leakage, but the Duracell wording is a little more ambiguous (and they wouldn't answer my request for clarification).
