There are many types of batteries, each suitable for different products. Lead acid batteries are a common type of storage battery, but once they are not used for a long time or have some malfunctions, they need to be repaired. The repair of lead-acid batteries is a highly technical task, and there are also many methods for repairing lead-acid batteries.
The first type is very simple and effective, and is also very suitable for non professionals to try, with very few devices used; Use an electric furnace wire to discharge all four batteries to 0V, and then use a charger to charge them. This lead-acid battery repair method greatly improves the battery capacity. Performing maintenance on normally used batteries once every three months can achieve good maintenance purposes and also extend the service life of lead-acid batteries.
The second method is to solve the vulcanization problem of batteries through overcharging. After a regular charger is fully charged, the light will jump and cannot be overcharged. We can use a 48V charger to charge a 36V battery, and a 60V charger to charge a 48V battery to solve the problem. However, we need to do a good job of cooling and limiting the current, controlling the temperature of the battery, placing it in water to cool it down, or lifting the battery cover and removing the rubber stopper can also effectively dissipate heat. Current limiting can be solved by connecting series resistance wires. A current overshoot of 5-10 hours can repair vulcanization.
The third method is to regularly check the temperature of the battery's bright body during the repair process of lead-acid batteries. When the overall temperature exceeds 40 (feels hot when touched by hand). It is necessary to check whether the charging voltage and current are too high. If they are normal, cooling treatment should be given.
When repairing lead-acid batteries, the first step is to identify the cause of the malfunction, and then use appropriate methods to repair it, in order to ensure that the lead-acid battery can be used normally after repair.
Secondly, it is to determine the fault. A common phenomenon regarding batteries in use is self discharge. This is because the lead powder fell off and settled at the bottom, causing a short circuit between the positive and negative plates. In this situation, it is necessary to clean the bottle chamber and remove the detached lead powder. You can punch a hole at the bottom of the battery, rinse it with tap water from the top hole, and then rinse it again with distilled water. Then fill the bottom hole and pour the poured battery solution back, only pouring out the lead powder. Not enough replenishment liquid. Generally, only one grid needs to be processed, not all.
Everyone knows how to vulcanize, so let's not talk about it.
When a large capacity water-based battery is damaged, the majority of cases are due to the detachment of the electrode plate. Unless the capacity is reduced due to vulcanization caused by the new battery being left for too long, this situation is rare. For most batteries such as car batteries and forklift batteries, the dielectric fluid continuously washes the electrode plate with the movement of the vehicle. The longer the use time, the more severe the detachment of lead powder, which is irreversible
