Lithium battery and lead-acid battery, which is safer?What is the difference between lead-acid batteries and lithium batteries

Lithium-ion batteries are safer than lead-acid batteries. Because the lead-acid battery has good heat dissipation, the battery is not prone to overheating, and the lead-acid battery has a good heat dissipation because the interior of the lead-acid battery is a lead plate. As for the heat dissipation of lithium batteries, the heat dissipation is relatively poor, because the energy density is too high.

The differences between lead-acid batteries and lithium batteries are as follows:

1. In terms of price: the price of lead-acid batteries will be cheaper, and the price is about 450Yuanup and down. The price of lithium batteries is slightly more expensive, generally 2 times that of lead-acid batteries, about 1,000 yuan;

2. In terms of service life: lead-acid batteries are not very durable and generally need to be replaced every 2 years. Lithium batteries can generally be used for 4 to 5 years. The lead-acid battery charge and discharge times are 300 times, and the lithium battery charge and discharge times are more than 500 times;

3. In terms of weight: when two batteries have the same capacity, the lead-acid battery will be heavier;

4. In terms of capacity: the voltage of lithium batteries will be higher than that of lead-acid batteries. The higher the average voltage, the higher the energy density of the battery. The same size of lithium battery and lead-acid battery, the capacity of lead-acid battery will be smaller than that of lithium battery;

5. In terms of safety performance: Lithium batteries are not stable and are prone to spontaneous combustion. We should be careful when using them.

Lithium batteries and lead-acid batteries have their own advantages and disadvantages. Car owners choose according to their own needs. The right one is the best. Don't blindly think that the expensive one is the best.
