PRODUCT DESCRIPTION

More peak cranking power. More battery capacity. More jump starts per charge. The Battery Tender® 1500 Amp Lithium Jump Starter is the portable car battery jump starter for drivers who want the extra headroom — 1500 peak Amps for larger engines, cold-weather starts, and hard-to-start vehicles, combined with a 12,000mAh power bank that charges devices multiple times and supports more jump start cycles before recharging. Handles any 12V gas engine up to V8 and diesel engines up to 7.0L.

1500 Peak Amps — Built for Bigger Engines and Harder Starts
1500 peak Amps delivers significantly more cranking power than 600 or 800 Amp units — the right specification for large displacement engines, diesel trucks, RVs, vehicles with high-compression engines, and any cold-weather start where battery output is reduced and extra cranking power is the margin between starting and staying stranded. Handles gas engines up to V8 and diesel engines up to 7.0L.

The Best Portable Jump Starter for Cold Weather
Cold temperatures reduce battery output dramatically — a battery that starts fine in summer may fail in below-freezing temperatures. Lithium jump starters maintain consistent peak Amp output in cold weather far better than lead-acid jump boxes, which lose significant capacity as temperatures drop. The 1500 Amp specification provides the buffer needed to start cold, marginally charged, or aging batteries that lower-output units cannot turn over.

12,000mAh Lithium Battery Pack
At 12,000mAh — nearly double the capacity of the 600 Amp unit — the Battery Tender® 1500 Amp supports more jump start cycles on a single charge and provides substantial USB charging capacity for phones, tablets, and USB-C devices. A larger internal battery means less frequent recharging and more confidence that the jump starter is ready after extended storage.

How to Jump Start a Car Battery
With the Battery Tender® 1500 Amp, jump starting a dead car battery without jumper cables takes under two minutes:

Connect the red clamp to the positive (+) terminal on the dead battery
Connect the black clamp to a ground point or the negative (−) terminal
Spark-proof connection technology confirms polarity before any current flows
Start the vehicle — crank for up to 5 seconds per attempt with 30 seconds between attempts
Once running, disconnect clamps and store the jump starter
No second vehicle. No waiting. No cable management. The 1500 Amp provides the cranking power to start most gas and diesel engines, even after extended discharge.

Portable Jump Starter That Fits Under the Seat
Despite 1500 peak Amps and a 12,000mAh battery, the Battery Tender® 1500 Amp remains compact enough for under-seat, trunk, or center console storage. Lithium technology delivers more power in less space than lead-acid alternatives — keeping the jump starter in the vehicle full-time without meaningful storage sacrifice.

USB Power Bank — Useful Every Day
The 12,000mAh battery charges phones, tablets, and electronics between jump start events — making the 1500 Amp a daily-use portable power bank that stays charged because it’s used regularly, not a device that sits discharged when the emergency finally arrives.
