Need to know

A3 questions, answered

Will A3 work with my vehicle?

A3 is for compatible 12V vehicle systems, with an engine reference of up to 8.0L Gas / 5.5L Diesel. Battery condition, temperature and engine condition affect starting. Use the Vehicle Fit Check and follow the product and vehicle instructions.

What do 2500A Peak and 800A Starting mean?

2500A Peak is the brief maximum output. 800A Starting is the rated starting current. Peak current is not continuous output; the vehicle and battery condition still affect the result.

How many starts can I expect from one charge?

50+ starts is the stated capability per full charge. Your actual number of starts depends on the engine, vehicle battery, temperature, remaining charge and connection setup.

What if the vehicle still won’t start?

Wait at least one minute between attempts and stop after three unsuccessful attempts. Follow the manual for disconnection and check the vehicle battery. See starting help or contact us with your vehicle details and clamp status.
