Questions and answers about car emergency starting power supply

The car emergency starting power supply is a practical tool used to assist in starting the car when the car battery is running low. You must have more or less questions about this type of product.  AMPROAD has comprehensively selected several common questions to answer for you.

 

 

  1. What is the Lifespan of an emergency vehicle start power supply (jump satarter) ?

In the case of regular usage, the lifespan of an emergency vehicle start power supply battery is generally 2-3 years. In practical terms, this is often defined as reaching the end of life when the battery's capacity has dropped to around 60%, accounting for the time effect on the Lithium battery jump starter. Since not everyone possesses professional knowledge about this, in simple terms, the cycle lifespan of an emergency vehicle start power supply is typically around 2-3 years. Users need not worry about the power supply they purchase having a short lifespan.

 

 

  1. Can an battery booster jump starter Completely Replace the Original Car Battery?

An emergency power supply is essentially a small-sized battery capable of instantly delivering the required starting current for a vehicle's emergency start. However, due to the rated power of the emergency power supply being much smaller than a regular car battery, and because the alternator's output power is designed for a standard car battery, the emergency power supply cannot be used to replace the car battery for long-term use.

 

 

  1. Do Car Batteries Store Power? Can a portable car jump starter be Used for Prolonged Periods?

No, they cannot. The emergency power supply's rated power is significantly smaller than a regular car battery, and the alternator's output power is designed for a standard car battery. Therefore, the emergency power supply cannot be used as a long-term replacement for the battery. The emergency power supply is a small battery designed to deliver the required starting current for a vehicle during an emergency, particularly when the battery lacks sufficient charge or experiences a performance decline. In other words, when the battery's charge is insufficient, the emergency power supply works in conjunction with the battery or independently starts the engine.

 

 

  1. Does Using an multi function jump starter Harm the Car's Original Battery?

Firstly, if we disregard the depreciation damage incurred during a car's normal use, using an emergency vehicle start power supply to start a car does not harm the vehicle.

 

Additionally, emergency vehicle start power supplies are generally high-rate discharge lithium batteries, which have different properties from the car's own battery (lead-acid battery). Moreover, when using an emergency vehicle start power supply, it is connected in parallel with the vehicle's battery. This is equivalent to parallel connection of two batteries with different properties. In this case, due to differences in capacity, voltage (if the car does not start, it means the car battery may be damaged or low on charge, with a low voltage), internal resistance, discharge characteristics, and other factors, they may mutually affect each other's service life. Over time, the use of two batteries connected in parallel can affect the stability of the internal materials of each battery, leading to a situation where they influence each other's lifespan."
