Hey guys. I bought this one via eBay from a seller located in California, since Amazon won't ship it to my house in argentina.

Seems legit enough to me. You got to be careful, there's a lot of fakes going around on eBay, like this one. It should have to have a clean black side instead of the old design for user-accesible batteries. Also notice the lack of rubber rings around the cables.

Still, i'm a bit worried about getting a fake. Any tips you can give me to check it once it gets to my home? How do you do that amperage test?

Thanks in advance guys!
