Likely there are several other possible problems. First, batteries generally have a 5-year life although that's only average under GREAT conditions and service. Second, connections on top of the battery may need to be cleaned. Third, many times the alternator is unable to charge the battery if it is not functioning properly. Have the output of your alternator checked to make sure it is providing between 13.8V and 14.4V. If not, it may not be capable of charging your battery. And last, your electrical system may have a drain on it (a trunk light or glove box light stays on).
My tip is for all makes and models of vehicles
It is a common fault these days are more and more extra fittings are loaded to the cars and when proper precautions are not taken it will end up to fault the system. Hence in case of a battery drain overnight try these checks.
You must check the drain current on your battery after the engine is switched off. The best way to check this out is to connect an ammeter in series to the battery and check. There can be a permissible limit of few milli amps but a large drain can in about 12 hours ( overnight) fully drain the battery no matter how much you have charged it or the system charged it up. Now disconnect one by one the circuits to centre on the faulty circuit and then the faulty device. This is easy as the fuse can be pulled out one by one till the ammeter reading drops down. Now it is always possible that directly connected circuits like Clocks, audio/video systems, remote control units , brake lamps park lamp circuits can be possible problem areas. After the device is identified and battery must be charged up fully and tested overnight.
disconnect one fuse every night with a fully charge battery until you have a fully charged battery the next morning or take it to a repair shop
Electrical shorts are tough enough to find if you are not a trained mechcanic
You either have a bad battery or a bad alternator. Most alternator shops and Advance auto parts store will check both for free. It is possible for an alternator to charge the battery while the car is running but kill it when it is switched off because of a bad diode in the alternator.
This seems to be an electrical Problem. Though it is Hard to Diagnose as all the wiring needs to be checked.As this is not a Common problem in RAM, i would advise you to Check all the wiring Connections. If you have Security Feature, you could try to De-activate that to check, if that would help this situation. For the time being, if you are not using the Car, you could pull out the Battery Cable to make sure, that the Battery is not Drained.
If you see Check Engine Light being ON, along with some driveability issues, you could take the Car to Autozone and Get the Codes Scanned that would tell you what exactly went wrong with this.
Hi:
Though your car seems fine without using the headlights, you have a charging problem, and need to get a couple things checked out. First make sure your battery connections are clean and tight. Your alternator belt should also be checked to make sure it is serviceable and properly tightened too. Your alternator should be checked under load, and lastly, your battery too. Most auto parts stores, such as auto zone,will check your parts for free,so you should only be spending money on what is broken!
Need to recharge the battery,fully,start the car,and check the charging voltage at the battery with a voltmeter, to verify that the alternator is charging the battery properly.If the alternator isn't working (charging) then the battery will go dead again.Charging voltage at the battery with the engine running should be minimum 13.5 volts up to about 14.5 volts.Battery voltage with the engine off should be minimum 12.5 volts.
