Yes this is actually the third battery am using now and whenever I pack and remove the terminal head of the battery I come back to start it one hand but when I leave the terminal head from evening to morning or for 10 hours the battery will run down

I would start by charging up the battery. You may have to disconnect from the vehicle.
Then have the alternator tested. The alternator not only produces the charge voltage+current but can draw from the battery. When you have it tested, have them check for abnormal draw.
Remove any add on accessory [even if it had been working fine] as they are typically the cause of the problem.
Once that is done determine the vehicle off state current drain. Search on "parasitic draw". Keep in mind that the expected number will not be zero. More details are in the threads that the search will find for you.
You can start pulling out the fuses to determine which circuit is drawing the current in off state.

Check for a bad voltage regulator, or a parasitic draw. AC voltage across the battery terminals while running will indicate a bad VR in the alternator. It will drain down a battery overnight with no other symptoms, often.
