battery problem

[Fazeel]

I got this new battery about 4 months back, but every now and then, the car refuses to start all of a sudden, cause somehow the battery dies out.

I went and got the battery checked and they said that its ok, so I dont know whats causing the problem ??

Is it not charging up or something, or are there some loose wires ??

And why does it not always happen ?? I mean once it breaks down and I charge it with wires connected to another battery, they its alright for over a week, and then suddenly I come home and then I want to go again after like an hour and it doesnt start !!

Sounds like its being drained by something permanent live?
You can check the voltage at the battery for charging / non charging easily enough with a volt meter (or get your mechanic to)
Not leaving something on that has a permanent live connection ? any after market accessories?

First step is to work through this guide: http://www.omegaowners.com/forum/YaBB.pl?num=1225724099

If the problem is intermittent I would be looking for a loose crimped connection to the battery / alternator / starter terminals or a loose grounding strap.
