The Differences Between Lithium Batteries And Lead-Acid Batteries
The Differences Between Lithium Batteries And Lead-Acid Batteries
From the market, it is known that there are various battery brands and qualities. What are the differences between lithium-ion batteries and lead-acid batteries? The following is an introduction to the differences between lithium-ion batteries and lead-acid batteries by a professional lithium-ion battery manufacturer, hoping to provide reference for customers or suppliers.
Lead-acid battery packs typically weigh 16 to 30 kilograms and are relatively large in size. But lithium-ion battery pack usually weigh 2.5 to 3.0 kilograms and are relatively smaller in volume. Therefore, lithium-ion batteries are lightweight and easy to carry. In terms of quality, it is difficult to define good or bad, but customers can purchase high-quality batteries produced by reputable manufacturers based on their actual needs.
1: Battery capacity
The capacity of a lithium-ion battery pack is generally 8 to 10Amps. The capacity of a lead-acid battery is approximately 20Amps.
2: Kilometer Travel
For example, for the same capacity 48V battery, when fully charged, electric vehicles with lithium-ion batteries and lead-acid batteries can travel 30-40 kilometers. The speed depends on the size of the electric motor used.
3: Durability
Lithium-ion batteries are highly durable, with slow power consumption. They can be charged and discharged more than 500 times without memory effect. The general service life is usually 4 to 5 years.
Lead-acid batteries are generally capable of being fully charged and discharged 400 times. They have a memory effect and have a lifespan of about 2 years. If maintenance-free lead-acid batteries are used, it is important to note that they lose less water and generally do not require adding distilled water during use. In terms of durability, lithium-ion batteries have excellent shock resistance. A fully charged battery in its complete charging state is safe and fixed. 1 hour, amplitude 4mm, frequency 16.7Hz. No leakage, no battery expansion or fracture, open-circuit voltage is normal. The battery can be charged for 48 hours at 0.1CA, without leakage, no battery expansion or fracture, open-circuit voltage is normal, and the capacity retention rate is above 95%; high current resistance, fully charged 2CA discharge for 5 minutes or 10CA discharge for 5 seconds, no conductive part fusion, appearance has no deformation.
4: Price and Warranty Period
Warranty period: The after-sales warranty period for lead-acid batteries is 1 year; the after-sales warranty period for lithium-ion batteries is 2 years.
Price: The price of lithium-ion batteries is higher than that of lead-acid batteries.
5: Environmental Protection
In 2012, the country issued the occupational entry conditions for batteries. After that, lead-acid batteries gradually took over the initial integration process. Now, most manufacturers have chosen to incorporate green production without cadmium and arsenic, which is more energy-efficient and environmentally friendly. However, only during the recycling process, methods may cause pollution. Lithium-ion batteries are relatively environmentally friendly in terms of production and recycling.
