Hi SRJ -

I can clarify. Don & I are describing the same thing. The batteries are shipped dry. You add the acid (it's easy), let it absorb, and then seal the battery. It is a sealed, maintenance free battery from that point forward.

GTX-14BS is a good number. Many manufacturers sell under that number, others cross reference to it. At any rate, you need an AGM battery that is 5.875x3.375x5.6875 inches. Go buy it at autozone. Take it out of the box and compare it to the one in the car, make sure they are the same physical size. If all is good, add the acid and pop it in the car.

No need to go to the dealer, they are selling the same thing. For the extra 30 bucks they will add the acid for you, that's all.

Trickle charging it is optional. The car will charge it for you, but you'll get the red warning at start until it is sufficiently charged. May take a few start cycles.
