What size battery can the NOCO GB40 jump start?

The NOCO Boost GB40 can jump-start vehicles with up to a 6-liter gas engine or a 3-liter diesel engine. This versatility makes it suitable for a variety of cars, trucks, and even some larger vehicles. The 1000A peak current rating provides ample power for quick starts, making it an excellent choice for those who need reliable jump-starting capabilities. For instance, it can easily handle most sedans, SUVs, and light-duty trucks. Pro tip: Always check your vehicle’s battery type and size to ensure compatibility before use. However, for heavy-duty trucks or commercial vehicles, you might need a more powerful jump starter or a dedicated truck jump starter instead.
