APC Universal Battery 70Wh + Asus Laptop

So I'm getting an Asus X83VM - X1, and I was a little disappointed to find out that Asus doesn't provide any 9-cell or 12-cell batteries for my model. Tom's Hardware had reviewed a Universal Battery manufactured by APC, and they seemed pretty pleased with it. What with it being discontinued (Along will all of APC's mobile products), they're probably going to be dropping in price pretty soon. I was a little let down when I saw that Asus wasn't listed at all on the list of laptops compatible with this battery pack. I was just wondering if anyone had heard anything about the battery's compatability with Asus laptops, specifically my own.
