Jump N Start 600 Amp Lithium Jump Starter

The Battery Tender® 600 Amp is the compact portable lithium jump starter designed to live in your glove compartment — so when your battery dies in a parking garage, a trail head, or a highway shoulder, you have everything needed to jump start your car without jumper cables, without a second vehicle, and without waiting for help. Small enough to forget it's there. Powerful enough to start any V6 gas or diesel engine up to 3.0L the moment you need it.

Portable Jump Starter That Goes Where You Go

At 6,400mAh in a glove-compartment-sized housing, the Battery Tender® 600 Amp lithium jump starter is the portable car battery jump starter you keep in the vehicle full-time — not in the garage for the one time a year you remember to bring it. The internal lithium battery holds its charge for months in storage, meaning it's ready when the battery fails, not just when you remembered to top it off last month.

600 Peak Amps — The Right Jump Starter for Most Vehicles

600 peak Amps starts passenger cars, compact SUVs, motorcycles, ATVs, powersports vehicles, and any gas engine up to V6 or diesel up to 3.0L. For larger engines — full-size trucks, diesel pickups, V8s — see the Battery Tender® 1500 Amp or 2000 Amp jump starter. The 600 Amp is purpose-sized as the everyday portable car jump starter for everyday vehicles.

How to Jump Start a Car With the Battery Tender® 600 Amp

Jump starting a car without jumper cables is faster and safer than the traditional two-vehicle method. With the Battery Tender® 600 Amp:

• Connect the red clamp to the positive (+) terminal on the dead battery

• Connect the black clamp to a ground point or the negative (−) terminal

• The spark-proof system confirms the connection before any current flows

• Start the vehicle — most engines start within 1–3 attempts

• Disconnect the clamps and store the jump starter

No second vehicle needed. No cable management. No waiting for roadside assistance. The process takes under two minutes from connection to engine running.

Jump Starter and Power Bank

The 6,400mAh lithium battery pack doubles as a USB power bank for phones, tablets, and electronics — giving the 600 Amp a daily use case that keeps it in the vehicle and keeps it charged. A portable jump starter you use every day is one you'll actually have when the battery dies.

Why Lithium Jump Starters Outperform Lead-Acid Jump Boxes

Traditional lead-acid jump boxes are heavy, lose charge rapidly in storage, and degrade significantly in cold weather. The Battery Tender® 600 Amp lithium jump starter weighs a fraction of lead-acid units, holds charge for months between uses, and delivers consistent peak Amp output even in below-freezing temperatures when batteries are hardest to start.
