Do the lights work and does it start the car? In U.S. a lot of parts stores will check it for free. There should be a sticker on it somewhere that has a letter/number on it like 1/7 which is the month and year it was sold. 1/7 would be January of 2007. That would let you know how old it was. You can just make brief contact across the terminal with a wire and see if you get a spark.

Well alternator charges battery can it still be bad?
A good lead/acid battery will measure about 13.2 vdc. If that is happening it seems to be good. A load test at your local battery sales point would tell you if it is bad. There are amp probes that clamp on the battery lead and will show the current flowing. If the car is starting and you are seeing a higher than 13.2 vdc at the battery (switching to 13.2 when the battery is charged) then the alternator is working and the battery is good. Clean terminals are needed.
