Jump starter NOCO GB251 24V 3000A portable lithium-ion vehicle starter for 24V systems

NOCO GB251 24V 3000A portable lithium-ion vehicle starter is a compact, rechargeable jump starter engineered for vehicles with 24V electrical systems. Designed to deliver a high peak current of up to 3000A, this unit provides on-the-spot starting power for trucks, buses and other commercial vehicles. The lithium-ion battery pack combines high energy density with a small footprint, allowing technicians and drivers to carry a reliable starter that can be used repeatedly for roadside assistance, fleet maintenance and workshop operations.

Advantages

The NOCO GB251 offers a high peak current output in a portable form factor, enabling fast cranking of large-displacement diesel and gasoline engines in 24V systems. Its lithium-ion construction reduces weight compared with traditional lead-acid jump starters while maintaining stable performance and multiple start cycles on a single charge. Built-in safety features protect against reverse polarity, short circuits and overcurrent, supporting safer handling during emergency starts and routine maintenance. Rechargeability and compact dimensions make the unit easy to store and transport between vehicles or across a service fleet.

Suitable for

• Starting trucks, buses and commercial vehicles with 24V electrical systems
• Roadside emergency jump starts for fleet vehicles
• Fleet maintenance, workshops and automotive service vans
• On-site vehicle recovery and transportation operations

Key specifications

• Operating voltage: 24 volts for vehicle systems
• Peak current: 3000 amperes for engine starting
• Battery type: lithium-ion rechargeable pack
• Design: portable, compact housing for easy transport
• Safety protections: reverse polarity, short-circuit and overcurrent safeguards

How to use

Ensure the jump starter is fully charged before use. Park the vehicle in a safe, stationary position and switch off ignition and accessories. Attach the starter's clamps to the battery or designated jump points on the vehicle, observing correct polarity. After secure connection, engage the starter according to the manufacturer's procedure and attempt to start the engine. Once the engine runs, disconnect the clamps in reverse order and recharge the unit as soon as possible to restore readiness for subsequent use. Follow vehicle manufacturer guidelines and local safety practices while performing starts.

Recommendations

Keep the device charged when stored and perform regular charge cycles if used infrequently. Store the starter in a dry environment and inspect clamps and cables for wear before each use. Use the unit only with compatible 24V vehicle systems and consult vehicle documentation for appropriate jump points and safety precautions.
