Can a portable NOCO Boost help start a vehicle after its battery has gone flat during winter storage? In this Handyman Problem Fixer video, the owner tests an older NOCO Boost power pack on a vehicle that will not crank. The video description reports about three months of Pennsylvania winter storage and a chilly day near 30°F.

Watch the original video on YouTube. This companion article is based on the original description and transcript; it adds general battery-safety guidance.

What Happens in the Demonstration?

At the beginning of the video, the driver tries to start the vehicle, but the engine does not turn over. The creator then connects his NOCO Boost power pack and activates it. After an initial attempt and a brief pause, the engine starts. The creator notes that this is the same power pack used in an earlier demonstration and that it has been around for at least a couple of years.

This shows one successful real-world attempt, not a controlled comparison or a guarantee for every completely discharged battery. Results vary with the booster model, battery condition, engine size, ambient temperature, cable placement, and state of charge of the booster itself.

Choose a Jump Starter That Fits Your Vehicle

NOCO makes several Boost models with different starting capabilities. A small portable pack may suit some gasoline engines but not larger engines or diesels. Before buying, compare the manufacturer’s stated engine-size ratings, operating-temperature limits, and battery-chemistry requirements with your vehicle. The exact model used in this older video needs to be confirmed before labeling any current product an identical replacement.

Connection and Safety Checks

Refer to the vehicle owner’s manual and the jump pack’s own instructions for the correct connection points and order. Inspect both batteries, leads, and clamps for damage. Keep clear of fans, belts, and moving engine parts, and avoid sparks or flames around lead-acid batteries. Never attempt to jump-start a visibly damaged, leaking, swollen, or frozen battery.

Some NOCO models have a manual override intended for particular low-voltage situations. Manual override may bypass protection features and must not be used casually or simply because a light appears on the pack. Follow the exact model-specific instructions rather than copying a button sequence from a video.

After the Engine Starts

Successful starting does not confirm that the battery has recovered. Have the battery and charging system tested if the vehicle has been sitting for months, repeatedly needs a boost, or will not restart. Recharge the jump pack according to the maker’s instructions and store it within the specified temperature range.
