A regular battery, also known as a lead-acid battery, has electrodes composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low cost; The disadvantage is frequent daily maintenance. Old style ordinary batteries generally have a lifespan of about 2 years and require regular checks of the electrolyte height and the addition of distilled water.

The biggest characteristic of maintenance free batteries, as the name suggests, is "maintenance free". There is basically no need to supplement distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self discharge. Of course, relatively speaking, its price will also be more expensive than ordinary batteries. As for the service life, the recommended replacement cycle for maintenance free batteries under normal circumstances is about 3 years.

Electric vehicle batteries are generally lead-acid batteries, which can be used for about 2 years under normal use, depending on personal driving habits. To prevent misleading usage and charging, the charging demand should be determined based on the electricity consumption. The method is as follows: when 100% of the battery is used up, the charging time is generally 8-10 hours, not exceeding 12 hours (which will affect the battery life). It is not recommended to use up the battery every time, and it is generally recommended to charge at around 70% of the electricity consumption. At this time, the charging time is generally 6-8 hours. If you are on a short trip, it is recommended to charge once a week when the daily electricity consumption is 10%. When the daily electricity consumption is 20%, it can be charged once every three days. When the daily electricity consumption is 30%, it can be charged every two days. When the daily electricity consumption is above 40%, it can be charged once a day. Control the charging time, usually around 6 hours. Prevent prolonged non charging after discharge. When not in use for a long time, it is necessary to ensure that the battery is fully charged before use, and it is generally recommended to recharge the battery within 2-3 months. If conditions permit, it is best to charge it once every 1-2 months; When electric vehicles are not in use, they need to be stored in a ventilated and cool room. After the battery pack is fully charged, the load line should be disconnected. Due to the self discharge of lead-acid batteries, it can cause sulfation. If not recharged for a long time, it will be difficult to restore capacity and affect battery life. Therefore, it is generally recommended to recharge the battery within 2-3 months to facilitate battery life. The current after-sales methods in the market: The warranty period provided by battery manufacturers to distributors is generally 15 months, with a period of 8 months for the first and 7 months for the second. Due to quality issues with the battery itself, new batteries are replaced within 8 months, turnover batteries are replaced within 9-11 months, and maintenance batteries are replaced within 12-15 months. At present, in the secondary market, the warranty period for users is generally one year, because there is a certain cycle from the factory to the dealership and then to the repair shop.

The lifespan of a battery is generally around 2-3 years, and if used and maintained properly, it can last for more than 4 years. If used and maintained improperly, early damage can occur within a few months. During use, the height of the electrolyte should be regularly checked, and the storage condition of the battery should be checked and replenished in a timely manner. The maintenance of batteries is relatively simple. By doing a good job in supplementing the electrolyte, cleaning the battery and pole piles, and controlling the specific gravity of the battery, the service life of the battery can be effectively extended. Due to the widespread use of maintenance free batteries, they generally do not require maintenance under normal operating conditions.

The design float life of domestic single 12V lead-acid batteries is 5-8 years, but they are completely scrapped within 1-2 years; Regardless of any lead-acid battery (including domestic and imported), there is always a vicious cycle of early scrapping in use. This is a globally recognized problem for over 140 years since the invention of lead-acid batteries - irreversible vulcanization of lead-acid batteries, which leads to a significant reduction in battery life and premature scrapping of batteries.

Reasons and manifestations of scrapping lead-acid batteries:

There are factors related to the intrinsic quality of batteries, as well as factors related to the usage methods and occasions of batteries, but over 80% of them are still due to the electrochemical reaction principle of lead-acid batteries themselves. A battery is a power source that can undergo reversible charging and discharging reactions. After discharge, the substances in the battery react and transform into a crystal called lead sulfate. After charging, lead sulfate is then converted into lead and sulfuric acid, resulting in a reversible reaction. However, when the reaction conditions are not complete and sufficient, lead sulfate cannot be completely converted, resulting in the accumulation of lead sulfate and reducing the amount of substances involved in the reaction. This is reflected in the decreasing battery capacity, ultimately leading to the loss of basic functions and becoming waste. This phenomenon in lead-acid batteries is called "vulcanization" (also known as aging).

During the charging and discharging process of lead-acid batteries, lead sulfate crystals gradually form on the electrode plate. This phenomenon leads to battery aging, which is manifested as: difficulty in charging and discharging the battery; Reduced battery capacity; Furthermore, it promotes the corrosion of the electrode plate and reduces the service life of the battery. The lead-acid battery extension maintenance device solves the above problems with ease. It can completely restore expired batteries caused by lead sulfate crystal formation. It not only brings huge economic benefits to users, but also saves a lot of natural resources and energy for the country, and reduces the serious environmental impact of waste batteries

Pollution. The widespread application of this technology will bring enormous benefits to the economy, environment, and society.

The normal service life ranges from 1 to 8 years, which is closely related to the condition of the vehicle. It can be used for more than 3 years when the vehicle's generator is charged back normally and there is no electrical leakage or grounding.

Car batteries are designed in such a way that they operate efficiently in temperate regions. Extreme weather conditions, especially cold weather, affect the battery of life. The energy generated by the battery is a result, a chemical reaction. How much does the low temperature increase and how much energy is needed to trigger this chemical reaction. As a result, the required energy for the battery exceeds the cost and begins to leave. The car that runs consistently in such a climate is destined to shorten your life.

I don't know if you can understand my explanation like this. If there are any further doubts

What are some bad habits in daily driving habits that can affect the service life of batteries that are usually replaced every few years? Today, we will talk about the topic of batteries.

Battery function

When the vehicle is ready to start, the battery is discharged to the starter motor, which drives the flywheel and crankshaft to rotate, thus starting the vehicle. When the engine power is insufficient or not started, it provides power to internal electrical appliances such as the audio system, lighting system, etc. When the engine starts supplying power normally, the battery will collect and store electrical energy for future use.

Automotive batteries can be roughly divided into two categories: maintenance free and regular batteries (non maintenance free).

The batteries used in passenger cars that we are all familiar with are basically two types: ordinary batteries and maintenance free batteries. At present, most models sold in the market use maintenance free batteries, while most Japanese cars use non maintenance free batteries, which are ordinary batteries.

A regular battery, also known as a lead-acid battery, has electrodes composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low cost; The disadvantage is frequent daily maintenance. Old style ordinary batteries generally have a lifespan of about 2 years and require regular checks of the electrolyte height and the addition of distilled water.

The biggest characteristic of maintenance free batteries, as the name suggests, is "maintenance free". There is basically no need to supplement distilled water during its service life. It also has the characteristics of shock resistance, high temperature resistance, small size, and small self discharge. Of course, relatively speaking, its price will also be more expensive than ordinary batteries. As for the service life, the recommended replacement cycle for maintenance free batteries under normal circumstances is about 3 years.

From the perspective of use and maintenance, whether your car is equipped with a maintenance free battery or a regular battery, the normal service life is around 2-3 years. As for extending the service life, ordinary batteries can be extended by adding electrolyte after about 3 years of use, thereby extending their lifespan by 1-2 years. As for maintenance free batteries, it's better to replace them directly, as there is basically no need to repair them.
