Battery light usually means alternator not charging. Most common solutions would be be a bad alternator, bad connection, or loose alternator belt. If the battery and alt test ok than check the connections to the alternator and battery.
You cannot charge a battery without a battery charger or having it charged by the alternator in your vehicle while it is running.
This could also be alternator problems as in a bad diode in the alternator.
i think you are having problem with your alternator its not charging your battery
check the alternator for most cars the alternator is wat powers the car the battery is for accesories... a quick check for alternator wit out having to disemble it tunr on ur car disconnect the postitive cable on the battery if car stays on then the alternator is good and the actual battery itself might be bad
If the light remains on then the system still isn't charging as it should. Check the plug on the alternator and also that the wires to the alt have a good connection.
It means you are having a problem with the charging system. Have the alternator and battery checked. Good Luck!!!

Yes, a loose battery cable will prevent the alternator from charging the battery. The drain on the battery is not caused by the engine not running unless an accessory is left on. Most likely, the drain is caused by accessories (radio, lights, etc) while the engine is running due to the battery not receiving its charge from the alternator and then not having enough charge left to start the engine.
If its standard then more than likely its the clutch.
You need to check if the ALTERNATOR is giving the correct output so as to charge the battery. By having a volt meter across the batery terminals one can then rev the engine and the voltage accross the battery should be about 13.8 volt indicating that the Alternator is charging the battery. If this 12 volt bateery voltage does not increase, this indicates a charging problem (mostly with the alternator either the brushes or one of the diodes in the alternator).
