Dead batteries are a common issue, especially if you have a lot of cars like a car flipper. In this article, we will discuss the essential tool you need to jump-start a dead car battery – the Jump and Carry JNC 770R.
This jumpbox has longer cables and a bent head, making it easier to reach difficult spots. It has a digital readout showing the power you’re giving the vehicle. The JNC 660 is almost identical to the JNC 770R, without the digital readout and with shorter cables.
To use the JNC 770R, connect the cables to the dead battery and turn it on. The engine should start after turning the key. It’s easier and more efficient than using traditional jumper cables, which might not give you enough power to start the car.
Using a jumpbox like the JNC 770R or JNC 660 has another advantage – it can verify that your alternator is charging the battery correctly. After starting the vehicle, you can see that the alternator is charging at 14.2 volts, which is what it should be doing.
The JNC 770R costs around $150, while the JNC 660 costs about $110. Both provide the same amount of power, so you should choose based on personal preference. Using a jumpbox is an essential tool for anyone dealing with cars, so if you’re in the market for one, we recommend the JNC 770R or JNC 660.
In summary, using a jumpbox like the JNC 770R or JNC 660 is an efficient way to revive a dead car battery. It’s a lot easier than using traditional jumper cables and can also verify that your alternator is charging the battery correctly. So, invest in a good jumpbox to make your life easier and save time.
