Lead-acid battery is a common battery, widely used in automobiles, electric vehicles, power tools and other fields. The service life of lead-acid batteries is affected by many factors, such as charging and discharging conditions, temperature, moisture, vulcanization, vibration and so on. If you do not pay attention to maintenance, lead-acid batteries are prone to problems such as capacity reduction, bulging, leakage, and short circuit.

Therefore, in order to extend the service life of lead-acid batteries and improve their performance and safety, we need to master some maintenance methods, as follows:

1. Avoid overcharging and overdischarging

Overcharge and overdischarge are the main reasons for shortening the life of lead-acid batteries, which can lead to the damage of electrode plates, the loss of active substances, the evaporation of electrolytes, and the precipitation of gases. In order to avoid overcharge and overdischarge, we need to use a suitable charger, charge according to the capacity and voltage of the battery, and do not charge or discharge for a long time until the battery cannot supply power. Ensure that the battery is replenished in time to avoid too low or too high battery power. If the battery is not used for a long time, it should also be charged regularly to prevent the battery from overdischarge.

2. Get hydrated

After the lead-acid battery is used for a period of time, the electrolyte in the battery will lose water because of electrolytic evaporation, if not timely water supply, the battery capacity will decrease, it is difficult to reach the rated voltage when charging, then charging is easy to cause bulging and even fire. Especially in the summer and autumn high temperature season, timely water supply is especially important.

The supplementary water is generally used as a battery special electrolyte, and must not be supplemented with tap water. When replenishment must be appropriate, when the electrode surface of the battery has a layer of water, it can not be filled, because the electrolyte is dilute sulfuric acid, the outflow of charging will lead to corrosion of the battery outside components, but also produce pollution.

Battery intelligent water supply system is a patented product independently developed by Lianhong, which is an automatic water supply equipment developed for rich liquid battery. Automatic water supply system is a reliable, convenient, stable and safe water supply system for forklift trucks and other electric vehicle rich liquid batteries. It can choose gravity automatic water supply without electric supercharging water supply. Can completely replace the battery manual water maintenance operation, real-time monitoring of the battery water shortage, automatic water supply, full water induction stop, after the installation of the equipment can keep the electrolyte level in a healthy state, to ensure the battery electrolyte characteristics stable and balanced, optimize the use of battery equipment efficiency, extend the service life of the battery.

3. Adjust your balance

Each single cell in the battery pack may have inconsistent capacity or voltage due to manufacturing or use, which will lead to reduced performance of the battery pack, and even overcharge or overdischarge. In order to adjust the balance of the battery pack, we need to regularly detect the voltage and capacity of each single battery, charge the battery with low voltage separately, discharge the battery with high voltage separately, so that the voltage and capacity of each battery are as consistent as possible.

A battery equalizer can be installed. A battery equalizer is an electronic protection device that prevents the voltage imbalance between battery cells in the battery from reducing the service life. When the voltage imbalance between battery cells, different battery cell charging and discharging speed is different, a battery cell charging completed colleagues, other battery cells are in the state of overcharging or undercharging, and overcharging or undercharging will damage the battery, resulting in reduced battery capacity and shortened life.

The battery equalizer can ensure the power balance between battery cells in real time, thereby extending the battery life by 5-30%. Through active equalization, the battery with high voltage is transferred to the battery with low voltage for compensation to achieve charging balance, so that each battery is full, and finally realize energy transfer to extend the battery range and battery life.

4. Keep the temperature right

Temperature has a great impact on the performance and life of lead-acid batteries, too high or too low temperature will reduce the capacity and efficiency of the battery, and even cause battery damage. In general, the appropriate operating temperature of lead-acid batteries is 15-25 ° C, if the temperature exceeds 40 ° C or below 0 ° C, the capacity of the battery will decrease significantly, and the effect of charge and discharge will become worse. Therefore, we should try to avoid the use or storage of batteries in high or low temperature environments, and if they must be used, some heat preservation or cooling measures should be taken, such as adding insulation layers or cooling fans.

5. prevent short circuit and vibration

Short circuit and vibration are the two fatal injuries of lead-acid batteries, which can lead to the increase of internal resistance of the battery, the rise of temperature, the loss of active substances, and the deformation of the plate, which seriously affect the performance and safety of the battery. In order to prevent short circuit and vibration, we should pay attention to the wiring and fixing of the battery to avoid contact between the positive and negative electrodes of the battery or contact with metal objects, resulting in short circuit. At the same time, it is necessary to ensure that the battery is firmly installed and avoid driving on the bumpy road, causing the vibration of the battery.

In short, in order to make lead-acid batteries more durable, they need to be properly maintained. Regular charging, avoiding deep discharges, avoiding high temperature environments, using the right charger and regular inspection and maintenance are all very important maintenance methods. If it can be maintained in accordance with these methods, the service life of the lead-acid battery can be greatly extended.
