The Battery Tender 2000 Amp Lithium Jump Starter is a portable 12V jump pack rated at 2000 peak amps, the highest output in Battery Tender's portable lineup. It is built for large-displacement gas and diesel engines, including V8s and full-size diesel trucks, and for deeply discharged batteries in cold weather. A 16,000mAh lithium pack is the largest in the line, giving more jump cycles per charge and enough capacity to charge phones and other devices over USB. It sits above 600 to 1500 amp units for drivers who need the extra cranking power without commercial-grade equipment.

The Battery Tender 2000 Amp Lithium Jump Starter delivers 2000 peak Amps of cranking power for 12V gas engines up to V8 and diesel engines up to 8.0L. It is the highest-output standard portable jump starter in the Battery Tender lineup. It is meant for full-size diesel trucks, large engines, extreme cold weather starts and deeply discharged batteries.
A 16,000mAh internal lithium battery is the largest capacity in the lineup. It provides power for multiple jump starts per charge and for charging devices through its USB outputs. The lithium battery keeps a consistent peak Amp output in cold weather and holds its charge for months between uses.
To use it, connect the red clamp to the positive (+) terminal of the dead battery. Connect the black clamp to a ground point or the negative (−) terminal. The spark-proof safety system confirms polarity before any current flows. Crank for up to 5 seconds, and wait 30 seconds between attempts. Once the engine is running, disconnect the clamps. No second vehicle is needed.
