What should I do if my starting power pack is dead?

Oct 21, 2025 Leave a message

A starting power pack is a lifesaver when your car won't start. But what if one day you find yourself running out of power? Don't panic! Here are a few simple solutions.

 

1. Common Causes of a Dead Starting Power Pack

Long-Term Use

Many car owners buy a starting power pack and leave it in their car for long periods of time. Over time, the power slowly drains.

A typical lithium battery-based starting power pack will self-discharge by about 3%-5% per month, even when not in use.

 

Ambient Temperature Too Low or Too High

If the battery is left in the sun in the summer or stored in sub-zero temperatures in the winter, the battery charge will decrease rapidly.

 

Battery Cell Aging

If a starting power pack has been used for more than two or three years, the cell capacity will decrease, resulting in slower charging and faster power loss, making it more likely to fail to charge.

2. How to Charge a Dead Starting Power Pack?

Using the Original Charger

The safest and most effective way is to use the charger that comes with the starting power pack.

After plugging in the power pack, check to see if the indicator light is on. Charging time for power banks varies by brand.

 

In-Vehicle Charging

Some jump starters support charging via a 12V car cigarette lighter, making them ideal for recharging while driving.

 

Type-C or USB Charging

Many new lithium-ion jump starters now support Type-C fast charging.

Easily recharge your battery at home, in the office, or in your car with just a single cable – convenient and practical.

 

3. Can I still start my vehicle if my jump starter is dead?

A jump starter requires a high instantaneous current to start the engine. If the battery is low and the output power is insufficient, the engine will not start.

Therefore, always ensure that the jump starter's battery is at least 80% before use.

 

4. How to determine the jump starter's battery level?

Most jump starters have a battery indicator:

Four lights on: 100% battery

Two lights on: Approximately 50% battery

One flashing light: Low battery, needs to be recharged immediately

 

5. How can I extend the life of my jump starter?

Charge regularly.

It is recommended to charge the battery every 2-3 months, even when not in use, to prevent the battery cells from over-discharging.

 

Avoid exposure to sunlight and moisture.

High temperatures will cause the battery cells to expand, while low temperatures will affect the current output.

Store the starting power supply in a cool, dry place.

 

Connect the cables correctly.

When starting the car, always clamp the positive (red) terminal first, then the negative (black) terminal.

After use, always remove the negative terminal first, then the positive terminal, to avoid short circuits.

 

Choose a reliable starting power supply.

There are many types of starting power supplies on the market. It is recommended to choose a well-known brand or one from a manufacturer with factory certification.

High-quality starting power supplies not only last longer but are also safer.
