If you are recharging a battery you will need to input more power than you could draw from the battery after charging, as the charging process is not 100% efficient. Most of this excess power will be lost as heat during charging.

You might need an Altenator!!
The voltage in your house is AC. It is in the form of a sine wave that goes positive and negative 60 times a second. To charge a battery you need DC so you do an AC to DC conversion and then apply the DC to the battery charging circuit that applies the correct charging current to the battery and checks on the state of the charge.
You should consult a cellphone repair expert for a device inspection
Check the voltage of your battery, first thing to do. It should be 12+ volts shown in you battery tester. Then, start the engine and check the battery voltage again. If the voltage goes up to 14 to 14+ volts, it means that your alternator is working. It's time for you to replace the battery.
This is not a battery problem. Your charging system, the alternator, is not putting out enough juice to charge the battery until you reach 4000 rpm. Have the alternator and charging system checked.
Sounds like your charging system isn't working and you are running off battery power until the battery goes dead. Have the battery and the charging system tested to determine what part is at fault.
Typically that means that the alternator is not functioning properly and is unable to maintain the battery charge. Many auto parts retailers will test the charging system for you, free of charge. If the battery light is on, have the charging system tested immediately, before your battery goes dead and you are unable to start the car.
