In fact, master some repair tricks, can make the lead-acid battery "revitalize", easily save the money to replace the battery.

In daily life and industrial production, lead-acid batteries are widely used, from electric vehicles to backup power supplies, are inseparable from it. However, as the use of time increases, the battery performance decreases, many people choose to replace directly, the cost is quite high. In fact, master some repair tricks, can make the lead-acid battery "revitalize", easily save the money to replace the battery.

## Deep discharge activation method

After long-term use of lead-acid batteries, lead sulfate crystals will form on the surface of the plate, affecting the performance of the battery. The deep discharge activation method can effectively break up these crystals. Before operation, ensure that the battery is in a safe environment and there is no open flame or flammable material around. First let the battery run under normal load until the voltage drops close to the minimum allowable value, such as the common 12V lead-acid battery, the voltage drops to about 10.5V. Then, a specialized deep discharge device is used to further discharge slowly, reducing the voltage to 9V-9.5V. Exercise caution when performing this operation to prevent excessive discharge from damaging the battery. After the completion of deep discharge, immediately use the matching charger to charge for a long time with a small current (generally 1/10-1/20 of the battery capacity), and the charging time can be controlled in 12-24 hours. After such a deep discharge and a long period of low current charging cycle 2-3 times, the lead sulfate crystals on the plate can be effectively decomposed, and the battery performance can often be significantly improved. For example, an electric vehicle whose battery life is greatly shortened due to aging has an increased range of 10-15 kilometers after being repaired by this method.

## Hydration repair method

During the charging and discharging process of the lead-acid battery, the moisture in the electrolyte will gradually decrease, resulting in an increase in the concentration of sulfuric acid, corrosion of the plate, and impact on the battery life. Hydration repair method can solve this problem. Prepare distilled water or special lead-acid battery supplement, syringes, rubber plugs and other tools. First open the rubber plug of the exhaust hole on the battery, use the syringe to extract an appropriate amount of distilled water or supplementary liquid, and slowly inject into each single cell battery, the injection amount is just to cover the plate, generally inject 5-10 ml per single cell. After injection, let it sit for 1-2 hours to allow the supplement to fully penetrate the plate. Then, the battery is connected to the charger and charged at the normal charging current. At the beginning of charging, the battery will be found to be hot and bubbling, which is a normal phenomenon. Continue charging for 8-12 hours, when the battery voltage is stable and does not rise, indicating that the water refill repair is complete. This method is significant for batteries with reduced capacity due to water shortage, and can restore the battery capacity to 70%-80%. For example, a group of lead-acid batteries used for emergency lighting, after water repair, the lighting time has been extended from the original 2 hours to about 1.5 hours.

## Pulse repair method

The pulse repair method uses the pulse current of specific frequency and amplitude to shock the battery plate and break the lead sulfate crystal. There are special pulse repair instruments on the market, easy to operate. Connect the positive and negative electrodes of the pulse repair device to the positive and negative electrodes of the battery, turn on the power supply, and set the repair time and pulse parameters according to the battery capacity and damage degree. Under normal circumstances, the repair time is 12-48 hours, the pulse frequency is between 1000Hz-5000Hz, and the pulse amplitude is adjusted appropriately according to the battery voltage. During the repair process, the repair device will emit a slight "sizzling" sound, which is a pulse current working. After the repair is complete, disconnect the repair meter and measure the battery voltage with a multimeter. If the voltage increases significantly, the repair is effective. For lead-acid batteries with severe plate vulcanization, pulse repair method can play a good role in repair, which can reduce the internal resistance of the battery and restore the capacity. For example, the lead-acid battery used by some electric forklifts, after pulse repair, the working time of the forklift is increased by 1-2 hours, which greatly improves the work efficiency.

## Balanced charging repair method

Multiple lead-acid batteries in series, in the process of use, the performance of each single battery will be different, resulting in a decline in the performance of the whole battery. The balanced charge repair method can balance the voltage and capacity of each single battery. Connect the battery pack to a specialized equalizing charger that provides the appropriate charging current and voltage for each cell individually. When charging, the charger monitors the voltage, current and other parameters of each battery in real time, and automatically adjusts the charging strategy, so that the charging state of each battery tends to be consistent. General balanced charging time is 12-24 hours, after the charging is completed, the voltage difference of each battery should be controlled within 0.1V. Through balanced charging repair, the whole service life of the battery pack can be extended and its performance stability can be improved. For example, the lead-acid battery used by the communication base station, after balanced charging and repair, the failure rate of the battery pack is significantly reduced, and the maintenance cycle is prolonged.

Master these lead-acid battery repair tips, can effectively extend the battery life, for us to save a lot of battery replacement costs. However, it should be noted that not all damaged lead-acid batteries can be completely repaired by these methods, and when the battery plate is seriously deformed, short circuit and other serious faults, it may still be necessary to replace the new battery. When repairing the battery, strictly follow the operation specifications to ensure safety.
