How to distinguish between lead-acid battery and lithium battery?

In terms of quality and volume, the lead-acid battery pack usually weighs 16-30 kg and has a relatively large volume; while lithium batteries generally weigh 2.5-3.0 kg and are relatively small in size, so they are light and convenient to ride. From the quality point of view, it is difficult to define the quality of the two, but consumers can buy good quality batteries processed by regular manufacturers according to their actual needs. In terms of battery capacity, the capacity of lithium batteries is generally 8-10 amps; the capacity of lead-acid batteries is about 20 amps. In terms of driving kilometers, for example, the same 48V battery, when fully charged, both lithium battery and lead-acid battery electric vehicles can run 30-40 kilometers, and its speed is importantly dependent on the size of the motor used. In terms of durability, lithium batteries have strong durability, slow consumption, charge and discharge more than 500 times, and have no memory. The general life span is 45 years. Lead-acid batteries generally have a memory within 400 times of deep charge and deep discharge, and their life span is about two years. If you are using a maintenance-free lead-acid battery, it should be noted that the battery loses less water, and it is generally not necessary to add distilled water during use. In terms of durability, the lithium battery has good vibration resistance. The fully charged battery is safe and fixed. It vibrates for 1 hour with an amplitude of 4mm and a frequency of 16.7Hz. There is no leakage, no battery expansion or rupture, and the open circuit voltage is normal; Good rechargeability, 25 degrees Celsius, fully charged battery 0.1CA for 48 hours, no leakage, no battery expansion or rupture, normal open circuit voltage, capacity retention rate above 95%; good high current resistance, fully charged state When the battery is discharged at 2CA for 5 minutes or at 10CA for 5 seconds, the non-conductive parts are fused, and there is no appearance deformation. In terms of price and warranty period, the mainstream battery currently on the market is 48 volts. If it is to be replaced, the lead-acid battery is about 450, and the warranty period is 1 year; the price of lithium batteries is relatively expensive, about 1,000 yuan, but the warranty period is 2 years. In terms of price and warranty period, the mainstream battery currently on the market is 48 volts. If it is to be replaced, the lead-acid battery is about 450, and the warranty period is 1 year; the price of lithium batteries is relatively expensive, about 1,000 yuan, but the warranty period is 2 years. In terms of environmental protection, the state promulgated the 'Access Conditions for the Storage Battery Industry' in 2012. Since then, the lead-acid industry has been re-integrated. Most manufacturers have adopted internalized cadmium-free and arsenic-free green processing, which is more energy-saving and environmentally friendly. In the recycling process, improper methods may cause pollution; lithium batteries are relatively greener in terms of processing and recycling. Among them, lead-acid batteries are the most numerous. Lead-acid batteries have the lowest price and are the most commonly used. my country is the world's largest processing country for lead-acid batteries. It contains less contaminated components and has good recyclability. The disadvantage is that it is smaller than the volume. In other words, under the same capacity, the weight and volume of the battery are large. The current lead-acid batteries are basically developed from floating-charge batteries. Floating charge batteries are not suitable for fast charging and high current discharge. Although technicians have spent a lot of effort to make effective improvements and can be put into practical use, their lifespan is still very unsatisfactory.
