If you need to replace your auto battery, always test it before you replace it. Also test the entire electrical system of your car. The reason for your battery problem might be a weak alternator or a drain on the system and if this is the case it won't take many weeks before your have to replace the new one as well. What seems to be a battery problem is not always caused by the battery itself. You can acquire more information about how to repair your car's electrical system on the web.
The car battery itself may be the cause if it has corroded cable terminals, bad wiring, damaged cells or plates inside or if it is leaking electrolyte. This article refers primarily to conventional vehicles with conventional 12-volt batteries; more electrified vehicles and those higher-voltage electrical systems will vary. The charging system warning light should show for a few seconds when you start the car, but if the battery light shows while you're driving the vehicle, that light signals a problem. Among other signs that the alternator or other parts of the charging system aren't working are dim headlights or the clock losing time.
