it's not really strong enough to start our cars with a dead battery, it's fine to assist in cold weather starting, but you better hook it up PRIOR to starting your car. not after your battery fails to start you.
for serious dead battery assists on our cars, you need a commercial 1200 CA which would be 900 or so CCA probably around 3000Peak amp packs... about 250.00
