Yes. Every couple of weeks I trickle charge it overnight. It accepts a full charge and slowly goes down until the next recharge. I have my charge port easily accessible from outside the car without having to open the hood and the charger is permanently mounted in my garage so it's a 10 second operation.

Would like to know what your statement of the need for "electronic testers that are programmed specifically for them" is based on. The link in your post does not work.
AGM battery still is a lead acid battery, it just is built differently but basic function of the battery is the same as traditional flooded lead acid battery.
I don't see any difference in load testing, i.e. you pull load from the battery and monitor voltage drop.

Just Google AGM batteries and you'll see the differences.

The link works fine for me Arrie. Here it is again :http://www.phillipsind.com/upload/re...1236015433.pdf

Well, in your reference site it gives three options for the AGM battery load testing. The first one "Carbon pile" I think is the most used for all battery testing. The third one requiring the specifically programmed tester is the one done with "Handheld micro processor based tester".
The instructions further explain how to pull half of the CCA rating amps from the battery for 15 seconds and monitor the voltage. If voltage is at or higher than 9.6 volts the battery is good.
There is nothing special in this.

I let my dealer service to change the battery for me just to keep good relationship going while the car is still under warranty. It probably cost me $100 or so more than if I did it myself.
Next time I will change it myself and it does not have to be an AGM battery either. It probably will though.
Normal flooded lead acid battery will work in our cars just fine too. Just need to have it at the same or higher CCA.

It's at the passenger end of the cowling outside. Close to the battery, easy to attach (don't even need to bend over), the hood line keeps away the air blast,water, and FOD, no extra anything required but I did zip tie it around the hood bracket just in case. I spliced some wires into the trickle charger (black&decker) plug, covered the splices and a good part of the wires with shrink tubing. I permanently mounted the charger in the garage above the spot and the cord just drops down to plug in. Multiple plug variations come with the chargers so you'll see which one you want to use. I'd stay away from the clamps though. I posted some pictures here somewhere. If you can't find them I'll take some more.

The 1st one shows the trickle charger connected. For convenience mount it in the rafters if you have to and extend the cord. My cord lifts out of the way and is kept up when not in use. The 2nd one shows how it exits into the cowl from the battery. No hole added it just fits under a rubber seal. The 3rd shows how it snakes from the battery. The 4th shows it again in the cowl. The last is another view of the wires coming from the battery posts and going up. You don't even notice the plug outside the car unless you know where to look and it's pretty protected from the elements. I knew if I didn't make the process easy I probably wouldn't do it as often.
