I have not driven my car for three weeks, i however warm it for at least 5minutes and sometimes 20mins daily.... Today my battery failed to start the car.... Another battery started the car without delay..... The battery is only 7 months old....

What could be the possible causes of this problem and how could we take better care of our batteries in the future?.... Thanks in anticipation

Is ur charging system (battery and alternator) ok? Do you have any after market gadget installed? By the way are we talking about a keke napep

Lol..... We are talking about a car..... Camry 05,i suspect the alternator is not charging the battery but how do i diagnose it?

The mechanic i saw just concluded that its the battery and he will charge it but i guess there is more to it..... Thats why i am here to get concrete opinions and suggestions before i see another mechanic. Thanks boss

Do you have a multimeter?

I dont have a multimeter..... Clearly i should get one

Against the backdrop that i am currently quite busy to spend time with mechanics and autos in diagnosing this problem....... How effective can i be if i get my battery charged and constantly disconnect my battery wen i park the car to avoid discharge...... On the chances the alternator isnt charging the battery. How long can i use this manoever before the battery discharges again?!...... Thanks in anticipation

Is it possible that my car mp3 which is never removed from its outlet was a cause of the battery drainage?
