Recently, some peoples have feedback that lead-acid batteries will cause battery leakage and do not know how to solve them. The following summarizes the analysis and solutions of this issue.
The safety valve acts as a seal under a pressure. When the specified pressure (opening pressure) is exceeded, the safety valve automatically opens and deflates to ensure battery safety. The main reasons for battery leakage of the safety valve are as follows.
a. Too much acid is added, and the battery is in a state of liquid, causing the gas channel for O2 reprocessing to be blocked. When O2 increases, the internal pressure increases. If the opening pressure is exceeded, the safety valve opens, and O2 is released with acid mist, which is opened many times, and the acid mist forms acid liquid around the safety valve.
b. The safety valve has poor aging resistance. After a period of use, the rubber of the safety valve is corroded by O2 and H2SO4, and the safety valve’s elasticity decreases, the opening pressure decreases, or even the long-term open state, causing acid mist and liquid leakage.
This is the case of acid leakage: there is actually a gap inside the two cylindrical terminals of the positive and negative electrodes. There is acid in this gap. Under normal circumstances, the acid will not leaked. When the following conditions occur, acid will leaked:
1. Excessive liquid level during acid filling will cause the acid leakage from the terminals.
2. There is a defect in the glue drop of the terminals.
3. Caused by the production process, or caused by too long welding time.
4. There is a problem with the exhaust valve, and the sealing is not good
5. Improper use of the charger, caused by overcharging
6. The terminal is clamped too tightly, causing acid leakage
The material of the poles of lead-acid batteries is generally lead and lead alloy, and the battery case is generally ABS or PP. The connection and sealing of the battery poles and the case have always been paid attention to, but there has always been a sealant for the connection and sealing of the two materials. The problem of sulfuric acid leakage occurs due to poor performance.
Sulfuric acid will corrode the poles and copper clamp terminals to produce powdery oxides that are not easily conductive, resulting in a decrease in charge and discharge performance. It is difficult for general users to eradicate.
Because a leaking car battery causes a lot of battery leakage, you shall consider to do the replacement of your car battery to avoid it from happening again faster.
Car Batteries are anyways counseled to switch each five years invariably to stay them in condition.
These clamps are one the simplest within the market and can facilitate stop more battery terminal corrosion. The clamps are made of preserved copper and make sure that the full clamp comes into contact with the electrical current.
One of the causes of battery leakage on terminals may be a battery that’s overcharged or undercharged. The manufacturer’s manual usually has the counseled battery voltage. check that you’re not charging it too arduous together with your automobile battery charger.
Also, check the voltage when the car is revving on idle with a multimeter. If the alternator is charging over 14.5 volts, there is something wrong with it.
Various sprays ar offered on the market to forestall terminal corrosion. you’ll conjointly use mineral jelly or grease if you discover the sprays costly. Coated felt pads might even be wont to stop corrosion of the battery terminals.
A car battery is a device that converts chemical energy into electrical energy. This means that the battery is full of acid. Battery leakage is an infrequent event. But when it happens, people can ask themselves “Is it safe to drive in the event of a leaking battery?”
It is not safe to drive with a leaking battery, because the sulfuric acid in a car battery is dangerous to the car, the user, and the environment. Battery acid will corrode engine components through oxidation. It will not dissolve plastic because the battery box itself is made of plastic. If it starts to leak under the car, sulfuric acid will dissolve limestone, cement and concrete. If you come into contact with sulfuric acid, it may eventually cause skin burns, throat irritation and breathing difficulties.
After such a problem occurs, it is best to replace the battery as soon as possible when there is battery leakage, because the battery terminals and the battery connection line are easy to loosen apart after being corroded. So the quality and safety are importance. Spaceflight power is your best choice!
