Car batteries include nickel cadmium batteries, nickel metal hydride batteries, lithium ion batteries, lithium polymer batteries and lead acid batteriesstrong>.
The differences between car batteries:
1. Nickel-cadmium (Ni-Cd) battery Voltage: 1.2V Life: 500 times Discharge temperature: -20 degrees ~60 degrees Charging temperature: 0 degrees ~ 45 degrees Note: Strong resistance to overcharge.
2. Nickel-metal hydride (Ni-MH) battery Voltage: 1.2V Life: 1000 times Discharge temperature: -10 degrees ~ 45 degrees Charging temperature: 10 degrees ~ 45 degrees.
3. Lithium-ion (Li-lon) battery Voltage: 3.6V Lifespan: 500 times Discharge temperature: -20 degrees ~ 60 degrees Charging temperature: 0 degrees ~ 45 degrees Note: Weight ratio Nickel- The batteries to metal hydride are 30% to 40% plus llightweight and their capacity is more than 60% higher than that of nickel-metal hydride batteries. However, it does not withstand overload. If overloaded, the temperature will be too high and the structure will be damaged, leading to an explosion.
4. Lithium polymer battery (Li-polymer) Voltage: 3.7V Life: 500 times Discharge temperature: -20 degrees ~ 60 degrees Charging temperature: 0 degrees ~ 45 degrees Remarks: Lithium battery The upgraded version does not has no battery fluid and instead uses a polymer electrolyte. It can be made into different shapes and is more stable than lithium batteries.
5. Lead-acid battery (sealed) Voltage: 2V Service life: 200-300 times Discharge temperature: 0°C to 45°C Charging temperature: 0°C to 45°C Note: For general vehicle use The battery (it is made up of 6 2V cells connected in series to form 12V), the lifespan of theThe battery without adding water can last up to 10 years, but the volume and weight are the most important.
The nominal battery life is 27 months. Generally, family cars are more economical. Many new car batteries last 3 to 4 years. However, after replacement, they generally need to be replaced after about 2 years. . Taxis are relatively expensive and a single bus lasts around a year, while a double bus lasts around 8-10 months.
Several factors that affect battery life are: vehicle condition, road conditions and driver habits.
In general, the newer a car is, the more battery it will save, because the engine is easy to use and saves battery, and the generator is easy to use and the battery can be fully charged when the vehicle is loaded. the car is getting old, especially after replacing the two granparts of the engine and generator. Due to the huge price difference between the original and refurbished products of these two products on the market, it is easy for car owners not to replace the original parts. and the battery will be damaged later.
Off-road batteries are often easily damaged. Car batteries have a technical index to indicate the anti-vibration performance of the battery! If the battery meeting the standard vibrates frequently in poor working environment, it will definitely be damaged.
The battery life is generally about two years
1: Excessive discharge
2: The battery is stored for a long time ( inIt was not charged during storage)
3: Cannot be charged by the car engine
4: No electrolyte
5: The density of the electrolyte is too high
6: Charging in unsuitable conditionshigh temperature ions
7: Contaminated by dirt (such as hydrochloric acid, sea water, organic acids, etc.)
8: When charging of the battery, add excessive current
9: Deformation of the electrode plate causes the positive plate and negative plate to contact, resulting in a short circuit
10: Dirt settles on the upper and lower parts of the plate, causing a short circuit
As long as you pay attention to avoiding the above points, your battery life will be increased accordingly.

Why is the car battery not replaced with a lithium battery?
It is a lead acid battery.
A lead-acid battery is a battery composed of lead and its oxides, and the electrolyte is a solution of sulfuric acid. The operating principle consists of convert chemical energy into electrical energy, which is used to meet the electrical needs of the car. Lead-acid batteries are the main type of car batteries, but with the development of technology, some new energy vehicles have also begun to use other types of batteries, such as lithium ion batteries, lithium iron batteries phosphate, etc.
1. With the same capacity, the cost of lithium batteries is much higher.
2. Lithium batteries cannot withstand large short-term current discharges (at start-up)
3. The capacity of a single lithium battery is limited.
4. Poor safety (may explode in case of crushing and collision)
Detailed information:
The battery is most afraid of low temperatures. In a low temperature environment, the caBattery capacity is much lower than that at normal temperature. Therefore, we should check and maintain in time, and pay attention to the following points in daily life:
1. Avoid parking the car in an open-air parking lot for a long time. for a long time, the battery should be removed and removed to prevent damage from freezing.
2. The car engine is not easy to start in winter. The car starting time should not exceed 5 seconds each time, and the interval between restarts should not be less than 15 seconds. If it still does not light up after several starts, the cause should be looked for in other aspects such as the circuit, ignition coil or oil circuit. Avoid starting multiple times without interruption, as this may cause the battery to drain due to over-discharge.
3. The car batteryre should be charged frequently. If the battery is not used for a long time, it will discharge slowly until it is discarded. Therefore, the car must be started from time to time. to charge the battery.
