What are the types of car batteries?

The difference between automotive batteries:

1. Nickel cadmium battery (Ni Cd) voltage: 1.2V, service life: 500 times, discharge temperature: -20 ° C to 60 ° C, charging temperature: 0 ° C to 45 ° C. Remarks: Strong ability to withstand overcharging.

2. Nickel hydrogen battery (Ni MH) voltage: 1.2V, service life: 1000 times, discharge temperature: -10 ° C to 45 ° C, charging temperature: 10 ° C to 45 ° C.

3. Lithium ion battery (Li lon) voltage: 3.6V, service life: 500 times, discharge temperature: -20 ° C to 60 ° C, charging temperature: 0 ° C to 45 ° C. Remarks: The weight is 30% to 40% lighter than nickel hydrogen batteries, and the capacity is more than 60% higher than nickel hydrogen batteries. But it is not resistant to overcharging, as overcharging can cause excessive temperature and damage the structure, leading to explosions.

4. Lithium polymer battery (Li polymer) voltage: 3.7V, service life: 500 times, discharge temperature: -20 ° C~60 ° C, charging temperature: 0 ° C~45 ° C. Remarks: The improved version of lithium battery does not have battery liquid, but uses polymer electrolyte, which can be made into various shapes and is more stable than lithium batteries.

5. Lead acid battery (Sealed) voltage: 2V, service life: 200-300 times, discharge temperature: 0-45 degrees, charging temperature: 0-45 degrees. Note: It is a general car battery (it is connected in series with 6 2V to form 12V), and a water free battery has a service life of up to 10 years, but its volume and weight are very large.
