Comparison between lead-acid battery type and lithium polymer battery type
Lead acid battery type
Advantages:
  • The starting current is high. Strong instantaneous discharge ability, able to easily drive large displacement diesel vehicles and heavy-duty vehicles.
  • Low cost. Lead acid battery type is an early type of emergency starting power source, with mature production technology and a much lower price than lithium battery products of the same specifications.
  • Low technical threshold. Simple structure, easy maintenance and replacement of parts
Disadvantages:
  • Large volume and weight. Usually weighing several kilograms, it has extremely poor portability.
  • The battery life deteriorates quickly. The charging and discharging cycle life is short, and long-term self discharge is severe.
  • Poor temperature resistance. The capacity and discharge capacity significantly decrease at low temperatures, and it is prone to bulging and leakage at high temperatures.
  • Poor environmental friendliness. Lead containing heavy metals, improper disposal after scrapping can easily cause pollution.

Lead acid battery type is mainly used for professional rescue in fixed places such as auto repair shops and roadside rescue stations, rather than for daily use by individual car owners.

Lithium polymer battery type
Advantages:
  • Small size and light weight. Most finished products weigh between 0.5-1.5kg and can be carried in the car without any burden.
  • Long cycle life. The number of charge and discharge cycles can reach 800-1000 times, which is 2-3 times that of lead-acid models, and the long-term cost-effectiveness is higher.
  • Low self discharge rate. Even if it is discharged for a long time, it can maintain battery life
  • Good temperature resistance. It can work normally in the temperature range of -20 ℃ to 60 ℃ (-4 ℉ to 140 ℉) and adapt to various climates. Its low-temperature starting performance is better than that of lead-acid models.
  • Safe and environmentally friendly. Does not contain heavy metals such as lead, there is no risk of leakage during use, and recycling after disposal has less environmental pollution.
  • Strong functional expandability. Integrated with multiple functions such as an air pump, power bank, and LED lighting, its practicality far exceeds that of lead acid

Disadvantages:
  • The price is on the high side. 2-3 times more expensive than lead-acid under the same specifications
  • Shortboard of high current. For large displacement, diesel vehicles may fail to start.
