Is it possible that my alternator is not charging the battery anymore? Is there a way to test alternator ?

There are multiple ways: with the Durametric software, using a multimeter, or with a load tester.

If you take it for a drive, does it charge up the battery? Does the battery go dead if you are using the car a lot or just when sitting for a few days?
Take the car to your local and get them to test the system. Takes just a few minutes to put the gauges on it and find out if there is a drain or if your battery is need of replacing.
My system was pulling power when everything was off. The first season was not bad. It took a week or so for the battery to die. Last season it was over night. Like I said it was regulator/alternator.

Set your multimeter to DC volts and connect to your battery and start the engine.....Should read 14+ volts. Alternator is OK and is charging the battery!

I bought a cigarette lighter, USB charger thingy, it also has a digital volt readout that displays to a 10th of a volt. It is as accurate as my meter. I keep it plugged in most of the time. I think I paid +/-$8 on Amazon.

I bought a multimeter with a DC clamp on ammeter to test things like this. Haven't tried it yet I would say defective battery (it happens), charging system problem as mentioned or a system drain. You just need to do some testing.
