Is it a good idea to jump start a car in the rain? As the electrical system in cars has a very low voltage, jump starting a car in the rain is completely safe and will not cause any harm to you. Since the voltage of your car is not high enough, there is no danger of being electrocuted. #batteryservice#exideservice#batteryexpert#maintenance#batteryshop#exidecare#batterystore#authoriseddealer#carbattery#bikebattery#inverterbattery#bestservice#batteryservice#exideservice#batteryexpert#maintenance#batteryshop#exidecare#batterystore#authoriseddealer#carbattery#bikebattery#inverterbattery#best service
