No, but the 12 volt outlet must be activated. On some cars you must have the ignition switch turned to accessory.
No. The alternator has to be turning to produce the charging voltage. It only turns when the engine is running.
your alternator charges the battery while the car is running. The alternator actually puts out a higher voltage than 14 volts while it is running, but it is reduced by a voltage regulator (most of which are already built into the alternator housing), to prevent damage and premature death of the vehicles battery. While your car is not running, the alternator is not charging the battery, and the 13.5 volt reading you get is just the measurement of the voltage the battery is holding at that given point.
If the car is left sitting for a long time and not running, yes. In some cars the cigarette lighter wont work unless the car is on for this reason.
If your 1997 Mercury Tracer has a battery light that blinks on and off while the car is running, it most likely means that the battery is not charging. This could be an issue with your alternator.
If the cause of the dead battery is from the charging system failure, yes.
No. The engine has to be running for the charging system to operate.
Maybe if you left it in there for a loooog period of time. I have left my cell phone charging (palm pre plus) in my car, with the engine off, for 4 hours and the car started fine.
Your car will have to at least have the battery running to charge the phone, but the engine does not have to be engaged.
not at all but if you dont use your car for a while and charge you phone inside its maybe possible but after a month or so if your battery is worn
a charger for the battery is provided along with the car it almost same as charging your mobile phone
Yes you can, you can listen to any iPod whole its charging in the car and if its hooked up to an AUX jack you still can.
No , for the battery to be charged the engine must be running . This means that your alternator , if it's functioning properly , is charging the car's battery as the engine is on/running .
