What is the difference between lead-acid batteries and lithium batteries?

1. Durability:

Lead-acid batteries generally have a deep charge and discharge within 400 times, have memory, and have a lifespan of about two years. If you are using a maintenance-free lead-acid battery, you need to pay attention to the low water loss of the battery, and generally do not need to add distilled water during use.

Lithium batteries have strong durability, slow consumption, charge and discharge more than 500 times, and have no memory. The general life span is 4-5 years. In terms of durability, the 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.

2. In terms of volume and quality:

General lead-acid battery packs weigh 16-30 kilograms and are relatively large ; Lithium battery is generally 2.5-3 kg, relatively small in size, so it is light to ride and easy to carry. As far as quality is concerned, it is difficult to define which one is better and which is bad. Consumers can purchase good-quality brand batteries produced by regular manufacturers according to their needs.

3. In terms of price and warranty period:

Currently, the mainstream battery on the market is 48V. If it is replaced, lead The acid battery is about 450 yuan, and the warranty period is 1 year; the price of lithium batteries is relatively expensive, requiring about 1,000 yuan, but the warranty period is two years.

4. Driving kilometers:

It is also a 48V battery. When fully charged, the lead-acid battery and Lithium battery electric vehicles can travel 30-40 kilometers. The speed mainly depends on the size of the motor used.

5. Battery capacity:

The lead-acid battery capacity is about 20A; the lithium battery capacity is 8-10A .

6. Environmental protection:

After the state promulgated the 'Lead Battery Industry Access Conditions' in 2012, the lead-acid industry After reorganization and integration, most manufacturers have adopted internalized green production without cadmium and arsenic, which is more environmentally friendly and energy-saving. Only in the recycling process, improper methods may cause pollution;

Lithium batteries are relatively greener and more environmentally friendly in terms of production and recycling.
