Car batteries, especially in cold climates, often face the problem of discharge. This can happen for many reasons: low temperatures, prolonged downtime of the car, forgotten headlights on, or simply an outdated battery. In such situations, a battery booster comes to the rescue – a compact device that can start the car engine even with a completely discharged battery.
Battery boosters have long-established themselves as a necessary accessory for motorists. But what is it, how does this device work, and how to choose the right option? Let’s take a closer look.
What is a battery booster
A battery booster (or jump starter) is a portable device for starting a car engine with a discharged battery. It is a powerful external energy source that is connected to the battery terminals via special clamps (“crocodiles”) and provides a short-term starting current to start the engine.
The battery booster has a compact size and light weight, which makes it convenient to store in the trunk or even inside the car. Modern models are often equipped with additional features, such as built-in lights, USB ports for charging gadgets, and even compressors for inflating tires.
Benefits of using a battery booster
Using a battery booster has a number of significant advantages:
- Autonomy. You don’t need to look for roadside assistance or depend on other cars. All you need is a booster in the trunk to handle a dead battery on your own.
- Multifunctionality. Most models are capable of not only starting the engine, but also charging phones, tablets, or other devices. Some models come with additional features, such as a built-in tire compressor, making them a versatile tool.
- Compactness. Battery boosters are small in size and weight, which makes them easy to store in your car and use when needed.
- Saving time. A booster eliminates the need to wait for assistance or to seek paid services such as calling a tow truck.
- Reliability. Modern devices are designed to operate in extreme conditions, including low temperatures and high humidity, making them useful in any situation.
How to choose a battery booster: main parameters
When choosing a booster, it is important to consider several key characteristics so that the device is suitable for your vehicle and operating conditions.
Starting current
This is the main parameter that you need to pay attention to. It shows what maximum current the booster can produce when starting the engine.
- For passenger cars, 200–600 amperes is sufficient.
- SUVs and light trucks require 600 amps.
- For large-sized equipment and diesel engines – from 1000 amperes.
Battery capacity
Measured in milliamp hours (mAh), it determines how many times you can use the booster without recharging. The larger the capacity, the longer the device will work.
| Vehicle type | Recommended capacity of battery booster |
| Car | 8000-12000 mAh |
| SUV | 12,000–15,000 mAh |
| Commercial transport | 15,000+ mAh |
Battery type in booster
There are two main types of batteries on the market:
- Lithium-ion. Lightweight and compact, with high capacity, they are suitable for passenger cars, but can lose efficiency at very low temperatures.
- Lead acid. They are reliable, produce more powerful current, and are suitable for large equipment. However, they are heavier and less compact.
Additional functions
Many modern boosters are equipped with additional functions:
- Built-in flashlight (useful at night).
- Charging USB gadgets.
- Compressor for inflating tires.
- LCD display for displaying charging status and operating parameters.
Operating temperature range
If you live in a region with harsh winters, make sure the booster can operate in low temperatures (down to -30 °C).
Size and weight
Make sure the device is easy to store in your car and does not take up too much space.
Quality and brand
Give preference to proven brands that provide a guarantee and have positive reviews. Popular manufacturers include: NOCO, CARKU, Schumacher, DeWalt.
Tips for using a battery booster
- Charge your device regularly. Even if the booster is not in use, its battery may be discharged. Check the charge level at least once a month.
- Observe polarity. When connecting to the battery terminals, make sure that the “+” of the booster is connected to the “+” of the battery, and the “-” is connected to the “-”.
- Do not use the device if it is damaged. If the booster housing is cracked or has other visible damage, use may be dangerous.
- Monitor the temperature regime. Do not leave the booster in the vehicle in extreme heat or cold conditions.
Battery boosters are easy to use, but it is important to follow certain rules:
- Prepare the device. Please make sure the booster is fully charged before use.
- Connect the clamps. Connect the red clamp to the positive battery terminal and the black clamp to the negative battery terminal.
- Start the engine. Turn on the booster and try to start the car. After successful start, immediately turn off the device.
- Charge the booster. After use, be sure to charge the device for further operation.
A battery booster is an indispensable assistant for any motorist. It eliminates many problems associated with a discharged battery and provides mobility in any conditions. Choose the device consciously, taking into account the starting current, battery capacity, additional functions and climatic features of your region. By investing in a quality booster, you provide yourself with peace of mind on the road and confidence in any situation.
