Frequently Asked Question (FAQ)

Can a car run without a battery?

Indeed, a can run without a battery, if the alternator is sufficiently large to help all of the electrical needs. In principle, yes you can, after the vehicle has been started. However, it is dangerous.

The alternator/generator attached to the motor ought to be structured and worked to supply enough power to keep the battery charged in any event when all the accessories are on – lights, wipers, heater, defroster, radio/sound system, everything (in any case, driving with everything on would kill the battery after some time).

In present-day vehicles, the alternator is also intended to run with the load of the battery in the electrical framework. The battery is viewed as a load as it is being charged by the alternator. Expelling this load (the battery) could damage the alternator or the implicit voltage regulator. Most alternators nowadays have worked in voltage regulators. Many vintage cars had an external voltage regulator (i.e.: not incorporated with the alternator or generator). On the off chance that the alternator/voltage regulator gets damaged because of running without the battery associated, the vehicle will probably pass on, leaving you stranded.

Current vehicles have PC controlled internal combustion motors. The ECU (PC) is usually reliant after accepting a clean supply of power. I.e.: the power has to reasonably be a steady voltage and liberated from spikes, drops, EMI, RFI, and so forth. Disengaging the battery while the motor is running could cause the power provided by the alternator to go past the range considered safe for the ECU, potentially browning the ECU. Again, should this happen, the vehicle will bite the dust, leaving you stranded.

Should the vehicle stall (e.g.: choosing too high a gear at a stop sign or light), without a battery, you have no easy/reasonable way of restarting the motor.

In this way, yes it is conceivable to start a vehicle, expel the battery, and drive the vehicle. Yet, it isn’t suggested.
