How often should a car battery be replaced? Car battery circle are different from other auto parts, and their service life is greatly affected by the usage conditions, not only car batteries, but also mobile phone batteries. For the same mobile phone, many people’s mobile phone battery will be greatly attenuated in the second year, and some people can use it for 5-6 years and still have it strong, which is related to the user’s usage habits.


The same is true for car batteries. Most car batteries are lead-acid batteries. Generally speaking, a 12V lead-acid battery is designed to have a floating charge life of 5-8 years, but in actual use, it will be completely scrapped in 1-2 years. ‘s abounds.

Uncover the Real Reason for the Aging of Lead-Acid Batteries

Many people are wondering, the battery is clearly marked as capable of reaching 500 charge-discharge cycles, why my battery can’t be used after more than a year of use, and the old king next door has been using it for four or five years, but the real culprit is that the battery is irreversible “vulcanization”. The characteristic of lead-acid batteries is that lead sulphate is produced inside the battery during discharge, and lead sulphate is converted during charging, and sulphide is gradually accumulated because lead sulphate is not converted, slowly eroding the capacity of the battery.

  • The vulcanization of the battery is inseparable from the use of the vehicle. In fact, long-term power feeding is the biggest battery killer. The lead sulphate formed by discharge after long-term power feeding is difficult to convert, and the probability of battery scrapping is greatly increased.
  • In addition, frequent over-discharge, high-power discharge, and insufficient charging can easily cause vulcanization of the battery, causing irreversible damage to the battery.

How to Better Protect the Battery?

  • Drive Often: If your car is idle for a long time, it is easy to cause battery feeding. Keep the frequency of driving at least once a week, and the driving distance should be at least 10 kilometers, so as to keep the battery at a basic level.
  • Pay attention to the electrical equipment in the car: For example, many netizens like to install various electrical appliances in the car, such as small refrigerators, rice cookers, electric fans, etc., but high-power electrical equipment will increase the burden on the battery system., reducing battery life;

Finally, be careful not to run out of battery power. For example: some people like to listen to music in the car after turning off the engine, but this will easily cause the battery to run out of power. After shelving, the battery will be in a feeding state for a long time. When driving, try to fill up the battery as much as possible.

Currently, electric batteries are not the most popular choice for a battery nor are they anywhere near being the most common used in cars on the road. However, as they continue to get more efficient, cheaper, and easier to dispose of, they can become the most common car battery in our world. It is just a matter of time before it happens, as being environmentally friendly becomes more popular and necessary.

If your car fails to catch fire after two days of parking, often prompts low battery after turning off, or the car engine prompts that the battery needs to be replaced, it means that you need to replace the battery, and it is more accurate to judge based on a variety of conditions.
