How long should you let a car idle to charge the battery?
If you find any of these cars start easily (the starter spins quickly), battery status is likely quite good, and a short drive or idling for 10 to 15 minutes may be adequate to keep the battery full, if done once every two weeks. If slower cranking is noted, a half hour drive once a week should do the trick.
Can I let my car idle all night?
It’s bad to idle your car overnight, but probably not as bad as you think. It won’t destroy your car in a single day, but it will do lasting damage, especially if you idle overnight repeatedly.
How long do you need to drive a car to recharge a dead battery?
One way to avoid early replacement is to recharge the battery and determine if it is dead or just in need of a recharge. Recharging the battery can take between a few and 30 hours. If you don’t have a battery charger handy, you can let the car’s alternator recharge the battery while the engine is running.
Does engine running idle still charge the car battery?
Yes, your car battery will charge while it is idling and this is possible because of the alternator in the battery itself. The alternator will charge the car’s battery by providing it with electricity. The alternator, on the other hand, is driven by the engine in your car.
Can a car start without a battery?
You can start a car without a battery and the car can run without a battery. If you have a manual trans its just a matter of push starting the car with someone pushing behind it. In order to start an automatic you would need to get the car up to a speed where the converter has enough pressure to lock up (never tried that before).
Will a car battery recharge itself after being dead?
Yes , a dead battery can be recharged provided that the battery cells inside the battery aren’t damaged. As long as the battery cells can still hold a charge an alternator or trickle charger would be able to recharge the battery to a fully charged state after a couple of hours.
