Ordering is easy although paypal would be nice. I bought the 22ah from here because it is a 22ah that has the same height as the 18ah batteries that I have been using meaning it will fit as an upgrade in my jump starter pack. this means that it has a greater density than the taller 22ah batteries on the market. It also works in a riding mower that it only has room for a smaller battery that is not the same size as the normal lawn mower battery. It also works great in my 2007 Prius at a MUCH better price than the Toyoyo battery that is an AGM battery as well. Thanks, J.
