Battery life test, how many years of lead acid battery service life

Ordinary batteries, also known as lead-acid batteries, its electrode is made of lead and lead oxide, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is that the voltage is stable and the price is cheap; the disadvantage is frequent daily maintenance. Old-fashioned ordinary batteries generally have a life span of about 2 years, and it is necessary to regularly check the height of the electrolyte and add distilled water.

Maintenance-free batteries, as the name suggests, are the most maintenance-free. It is basically unnecessary to replenish distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size and small self-discharge. Of course, its price will be more expensive than ordinary batteries. As for the service life, the recommended replacement period for maintenance-free batteries under normal conditions is about 3 years.

The electric vehicle battery is generally a lead-acid battery, which can be used for about 2 years in normal use, which is related to personal car habits. Eliminate the misuse of charging with the use, the charging should be determined according to the power consumption, the way is as follows: 100% of the use of electricity, the general charging time will be 8 to 10 hours, not more than 12 hours (for battery life will Influential), it is not recommended to use up the electricity every time. It is generally recommended to use about 70% of the charge. The charging time is usually 6~8 hours. If you are on a short trip, the following is recommended: When the electricity consumption is 10% per day, you can charge it once a week. When the electricity consumption is 20% per day, it can be charged once every three days. When the electricity consumption is 30% per day, it can be charged once every two days. When the daily electricity consumption is above 40%, it can be charged once a day to control the charging time, usually around 6 hours. Do not charge for a long time after discharge. If it is not used for a long time, it must be done: the battery must be fully charged before being put on hold, and it is generally recommended to recharge the battery in 2 to 3 months under the premise of full power. If conditions permit It is best to charge once every 1~2 months; when the electric car is not in use, it should be stored in a cool and ventilated room. When the battery pack is fully charged, the load line will be disconnected. The self-discharge of the lead-acid battery itself will cause sulphation. If the power is not replenished for a long time, the capacity recovery will be difficult to affect the life. Therefore, it is generally recommended to recharge the battery in 2 to 3 months to facilitate battery life. At present, the after-sales method on the market: the battery manufacturer's warranty period for the dealer is generally 15 months, the first 8 after 7, due to the quality of the battery itself, the replacement battery within 8 months, 9 to 11 months for the turnover battery, Change the maintenance battery for 12 to 15 months. At present, the shelf life of users in the secondary market is generally one year. This is because there is a certain period from the factory to the distribution office to the repair shop.

The life of the battery is generally about 2-3 years. If it is used and maintained properly, it can be used for more than 4 years. If used and maintained improperly, it will be damaged early in a few months. The battery should be regularly checked for the height of the electrolyte during use, and the battery storage condition should be checked and supplemented in time. Battery maintenance work is relatively simple, do a good job of electrolyte supplement, battery and pole cleaning and battery specific gravity control, can effectively extend the battery life. Due to the widespread use of maintenance-free batteries, batteries generally do not require maintenance under normal operating conditions.

The domestic single-cell 12V lead-acid battery has a floating life of 5-8 years, but it has been completely scrapped in 1-2 years; no matter what lead-acid battery (including domestic and imported), it can't escape the strange scrap in advance. This is the world-famous problem that lead-acid batteries have been invented for more than 140 years. The “irreversible vulcanization” of lead-acid batteries has led to a significant reduction in the service life of batteries and the early retirement of batteries.

Lead-acid battery scrapping reasons and performance:

There are factors in the internal quality of the battery, as well as the method of using the battery and the occasion, but more than 80% are due to the electrochemical reaction principle of the lead-acid battery itself. The battery is a power source that can perform a reversible reaction of charge and discharge. After the discharge, the substance in the battery reacts and transforms into a crystal called lead sulfate. After charging, the lead sulfate is converted into lead and sulfuric acid, so that the reaction is reversible. However, when the reaction conditions are not complete and sufficient, lead sulfate cannot be completely converted, resulting in the accumulation of lead sulfate, thereby reducing the amount of substances involved in the reaction, which is reflected in the battery output is less and less battery capacity. Eventually it loses its basic function and becomes waste. This phenomenon of lead-acid batteries is called "vulcanization" (also known as aging).

Lead-acid batteries gradually produce lead sulfate crystals on the electrode plates during charge and discharge. This phenomenon leads to the aging of the battery, which is characterized by: difficulty in charging and discharging the battery; lowering the battery capacity; further promoting the corrosion of the electrode plate to reduce the service life of the battery, and the lead-acid battery extension maintenance instrument solves the above problems. It can completely recover the battery that has expired due to lead sulfate crystals. While it brings huge economic benefits to users, it also saves the country a lot of natural resources and energy, and reduces the serious environmental pollution of used batteries.

Pollution: The widespread use of this technology will bring huge benefits to the economy, the environment, and society.

The normal service life varies from 1 to 8 years, which is closely related to the condition of the vehicle. It can be used for more than 3 years in the case where the vehicle generator is back-punched and the electric appliance has no leakage.

Car batteries are designed in such a way that they are in their temperate zone where they operate efficiently. Extreme weather conditions, especially cold weather, affect a battery of life. The resulting energy battery is a result, a chemical reaction. How much heat is added and how much energy is needed to trigger this chemical reaction. As a result, the energy battery needed to leave beyond the cost. That car consistently runs like this climate destined to shorten your life.

I don't know if I can explain this. Can you understand? If there is still doubt

How many habits in the process of daily use of the battery will change the battery life? Today, we will talk about the battery.

Battery function

When the vehicle is ready to start, the battery is discharged to the starter, and the starter drives the flywheel and the crankshaft to rotate, thereby starting the vehicle. When the engine is under-powered or not started, power is supplied to the interior electrical appliances such as the sound system, the lighting system, etc. When the engine starts to supply power normally, the battery collects and stores the electrical energy for later use.

Automobile batteries can be roughly classified into maintenance-free and ordinary batteries (not maintenance-free).

The batteries used in passenger cars that we are all familiar with are basically two types of batteries: ordinary batteries and maintenance-free batteries. Most of the models currently on the market use maintenance-free batteries, and most Japanese cars use non-maintenance batteries, which are ordinary batteries.

A common battery is also called a lead-acid battery, and its electrode is composed of an oxide of lead and lead, and the electrolyte is an aqueous solution of sulfuric acid. The main advantage is that the voltage is stable and the price is cheap; the disadvantage is frequent daily maintenance. Old-fashioned ordinary batteries generally have a life span of about 2 years, and it is necessary to regularly check the height of the electrolyte and add distilled water.

Maintenance-free batteries, as the name suggests, are the most maintenance-free. It is basically unnecessary to replenish distilled water during the service life. It also has the characteristics of shock resistance, high temperature resistance, small size and small self-discharge. Of course, its price will be more expensive than ordinary batteries. As for the service life, the recommended replacement period for maintenance-free batteries under normal conditions is about 3 years.

From the point of view of use and maintenance, whether your car is equipped with a maintenance-free battery or an ordinary battery, the normal service life is about 2-3 years. As for the extension of the service life, the ordinary battery can be added after 3 years of use, so that the life of 1-2 years is extended. As for the maintenance-free battery, it is recommended to change it directly, and it is basically impossible to repair.
