The design life of the battery is 27 months. The average family car is relatively economical. The battery of a new car is used for 3-4 years, but after a replacement, it usually needs to be replaced in about 2 years. Taxis are more expensive, and a single train can last for about 8-10 months for a double train.

　　Several factors affecting battery life are: vehicle conditions, road conditions, and driver’s habits

　　Generally, the newer the car is, the more the battery is saved, because the motor is easy to use, the battery is easy to use, and the generator is easy to use. The battery can be fully charged. The price difference between the original and refurbished products is huge, so it is easy for car owners not to replace the original parts, and then the battery is more likely to break.

　　Often off-road batteries are easy to break, and car batteries have a technical index to indicate the anti-vibration performance of the battery! If the working environment of the qualified battery is not good, it will often vibrate, of course, it will be bad.

　　What are the battery types of cars?

　　1. Nickel-cadmium battery (Ni-Cd) Voltage: 1.2V Service life: 500 times Discharge temperature: -20℃～60℃ Charging temperature: 0℃～45℃ Remarks: Strong overcharge resistance.

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

　　3. Li-ion battery (Li-lon) Voltage: 3.6V Service life: 500 times Discharge temperature: -20℃～60℃ Charging temperature: 0℃～45℃ Remarks: The weight is 30% lighter than Ni-MH battery. 40%, the capacity is more than 60% higher than the nickel-hydrogen battery. But it is not resistant to overcharging, if overcharging will cause the temperature to be too high and destroy the structure => explosion.
