Getting the most out of your NOCO GB70 starts with understanding its core identity as a sophisticated piece of rescue equipment rather than just a basic jump starter. This intelligent lithium iron phosphate (LiFePO4) device is engineered to safely revive a dead vehicle battery while protecting your modern car’s sensitive electronics. Unlike older, bulkier lead-acid jump starters, the GB70 is compact, safe, and designed for the long term, making it an essential tool for both everyday drivers and professional technicians who refuse to compromise on performance or safety.
Understanding the NOCO GB70 Technology
The foundation of effective usage lies in appreciating the engineering behind the GB70. Its standout feature is the patented Safe-ER technology, which utilizes a low-impedance design to deliver a powerful, controlled surge that cranks even the most stubborn engines. Because it is based on LiFePO4 chemistry, it offers a significantly longer service life, thousands of charge cycles, and superior thermal stability compared to standard lithium-ion batteries. This inherent stability means the GB70 can be stored for extended periods without losing its charge and operates safely in a wide range of temperatures, from a sweltering summer day to a freezing winter morning.
Preparing for Your First Jump Start
Before you connect the clamps, preparation is the key to a smooth and safe procedure. Ensure the NOCO GB70 is fully charged by plugging it into a wall outlet using the included micro-USB cable; a green LED indicator will confirm it is ready. Park the vehicle with the dead battery next to your GB70 so the clamps can easily reach the battery terminals without stretching. It is critical to inspect the battery terminals for any corrosion, dirt, or grease; clean them thoroughly with a wire brush to ensure a strong, conductive connection. For safety, turn off the ignition, headlights, and any other electrical accessories in the vehicle that needs to be jumped.
Step-by-Step Connection Process
The connection sequence is designed for foolproof safety, so follow these steps exactly. First, attach the red positive (+) clamp to the positive terminal of the dead battery. Second, connect the other red clamp to the positive (+) terminal of the NOCO GB70. Third, attach the black negative (-) clamp to the negative terminal of the GB70. Finally, connect the remaining black clamp to a clean, unpainted metal ground point on the engine block or chassis of the vehicle with the dead battery, as far from the battery as possible. This final step minimizes the risk of sparking near the battery, which is crucial for safety.
Executing the Jump and Post-Operation
With all clamps securely connected, start the vehicle with the dead battery. You may need to wait a few moments for the GB70’s power to stabilize the battery voltage before the engine turns over. Once the vehicle fires up successfully, carefully reverse the connection sequence in this exact order: disconnect the black clamp from the vehicle’s ground, then the black clamp from the GB70, followed by the red clamp from the GB70, and finally the red clamp from the revived battery. Let the vehicle’s alternator charge the newly revived battery for at least 15 to 30 minutes of driving to ensure the charging system is replenishing it properly.
Advanced Features and Maintenance
Beyond jump starting, the NOCO GB70 functions as a versatile power bank, thanks to its USB-A and USB-C ports. You can use these ports to charge smartphones, tablets, GPS devices, and other USB-powered gadgets during road trips, emergencies, or daily commutes. The device includes a built-in LED flashlight with multiple modes, including a bright steady beam and a strobe function, which can be invaluable for roadside repairs or emergencies at night. To maintain peak performance, it is good practice to charge the GB70 every few months if it is not in regular use, preventing the internal battery from depleting completely.
