JohnnyScience they aren't based in the US, so shipping can take from 3 weeks to infinity, depending on where you are located on the globe.
Maybe you can buy one from the manufacturer if you must have one? I'm a bit confused about why the cord is such a dealbreaker for you, I mean, you already have what you need? I've owned one of those batteries with that charger, and it was perfectly fine, usable, and etc. If you must have one more quickly, why not check out the manufacturer's site or see if you can find one from a US based vendor.
