    I have a question quite important to me:
    Car: VW Polo 1.4 petrol, 44 Ah battery, 4 months old
    After the failure, there is no V-belt, and therefore no power steering and no alternator. And here you have to get to the workshop somehow. At this point, the question arises: how long will the car last on the battery alone, I assume driving up to 2000 rpm. And the headlights are on normally.

    I'm asking because I don't know if I should take a tow truck.

    Regards.

    if well charged, I think 15-20km. Of course, if you don't get stuck in traffic.
    Time is more important than distance

    In the past, when the belt failed, a woman was undressed from tights and somehow reached the destination without lights. I drove about 40km (there was no own woman at hand, and harassment of random people can be dangerous).

    Gentlemen, what is the discussion about. I've already seen the effects of such a ride. The pillow drivers give the body first.

    You won't get much on it, but you can get there ;)

    I had a similar case, the electricity was enough for less than 40 km. but without the lights it will definitely go half way further.

    I don't know how in this engine with a cooling pump - belt drive or timing belt?

    And here I agree with my colleague, at the end of such a drive there can be many errors in the drivers.

    Thanks all for the replies. And I'm already writing:

    :arrow: salmon : The water pump on the timing belt, so it shouldn't overheat.

    If there are mistakes, it's hard, maybe you can deal with them somehow. I'm sure they'll be fine in the workshop. If only to arrive.

    I wonder how much electricity the computers and the ignition consume during operation, because light bulbs are known (all together about 200W, I think).

    It's supposed to be close, about 6 km, but it's through the city. Well, let's see if it works. I will write about the effects. Oh, I'll be driving with a voltmeter connected to the cigarette lighter. That way I should probably know how much more the battery can do. I can make it to 10 volts.

    Regards.

    6km, you can only charge the battery with a rectifier before this ;)

Topic summary

The discussion revolves around the feasibility of driving a VW Polo 1.4 petrol with a 44Ah battery after an alternator failure, specifically without a V-belt, which results in no power steering or alternator function. Users estimate that the car can travel approximately 6 to 40 kilometers on battery power alone, depending on driving conditions and whether headlights are used. Some responses suggest that the battery could sustain driving for 2-3 hours, while others emphasize the importance of avoiding traffic to maximize distance. The author plans to monitor battery voltage during the drive to assess remaining capacity and is concerned about the electrical consumption of the vehicle's systems. The water pump is confirmed to be on a timing belt, reducing overheating risks.
