2011 Grand Cherokee - AGM Battery

Why did Jeep decide to put the battery under the passenger seat, where the only way to get to it is to remove the passenger seat? Also I read AGM (Absorbent Glass Mat) batteries cannot be charged in the traditional way (it takes a few hours to charge it). Are these AGM batteries dependable in a Jeep?

It comes down to packaging. The front of vehicles are smaller for aerodynamics which makes it harder to put everything under the hood. Moving the battery also moves a heavy object from the front. It might also reduce vibration to the battery since it is closer to the center of the vehicle. And the battery is away from the engine heat which can kill a battery.
At least you don't have to take off a wheel and inner fender liner to replace the battery like on lots of cars. On the Chrysler 300 and Dodge Charger the battery is in the trunk. And I think some Buick's have the battery underneath the rear seat.
Optima batteries are AGM and can be charged at 13.8 volts so I don't know why Jeep's AGM battery needs to be charged at 12.65 volts. Not being able to use a regular charger is stupid.

I know on the M-Class suv there is a jumper box in the engine compartment that you can use to jump start the car or charge the battery, There battery was under the passenger seat also.

The battery ought to be in the rear, behind the passenger side wheel well. Better weight distribution, and room for a nice 1150 CCA AGM battery or two.

Update

UPDATE: I recently read that the AGM battery under the passenger seat has an access panel which you can open by adjusting the passenger seat all the way foward, exposing the negative terminal (and assuming positive as well). Also read that the battery will have pos & neg charging posts under the hood, so you can still charge it the normal way.
