My Opel Astra does not start after changing alternate

Hello everyone, after changing the alternator, and the battery although new, it was downloaded and has been used at least 5 months, they left me a portable device that they call starter, connect it to the terminals of the battery, the box on and made the attempt to start but I did not start.
My question is, do I need to put a full charge to the battery?

Hi, you would have to prompt with a well charged battery to get out of doubt and rule out that it was the battery .. greetings you will tell me

Hello partner according to accounts you have had the battery put to the car for five months without using. As long

Please companion where the brooms of the start -up are. How do you see I am a firecracker.
Thank you.

You can hit him (with a little tention to not load anything.) To the starter engine so that they sulate the brushes, but I doubt that they are stuck, most likely the battery is vague, you should try another. Salu2
