Big differance between a "sealed" battery and a gel battery. The 950 has a gel battery in it that can be mounted upside down if need be and they're WAY more money. You can see in the Sears picture of the sealed battery that it comes with acid that YOU have to put in...than "seal" it up.
I had a Yuasa shit the bed in a year and a half and just replaced it with a Interstate gel. Let's see how long that lasts.
