Battery repair - is it a cutting-edge technology or just a waste of money? The veteran said it like

"The battery doesn't last long; can't we just add a bottle of electrolyte to fix it?" "Online, they say adding water for just a few yuan can repair it. Are you trying to overcharge me?" As an electric vehicle user, have you ever had such questions? Today, we will unveil the mystery of "battery repair" and see if it actually works!

Battery type



First of all, it is necessary to clarify that the lead-acid batteries used in electric vehicles are mostly valve-regulated lead-acid batteries .
The so-called "'valve" refers to the pressure relief valve on the battery. lts function is to balance the internal andexternal pressures. Once it is opened, in addition to automatically losing the manufacturer's three-yearwarranty, it is often accompanied by the loss of electrolyte. This is precisely why some people try to add water(distilled water) - by diluting the electrolyte concentration, they hope to improve the ionization state.
The so-called "battery that can be repaired by adding water" that people often mention is usually an electrolytebattery (also known as a "rechargeable battery"'). This type of battery is commonly used in cars andmotorcycles. it has a large discharge current, the electrolyte is prone to leakage, and it requires frequent waterreplenishment. However, it is definitely not the same as the type of battery found in your electric vehicle!

Fixing the battery is mostly in vain.



Theoretically speaking, a single lead-acid battery can indeed be restored to some extent through professional methods. But the problem is: Your electric vehicle is powered by the entire set of batteries working together! Adding water at will for repair is very likely to cause the voltages of individual batteries in the battery pack to be mismatched. The symptoms manifested are as follows: It seemed to work at first, but after a few days of use, it immediately returned to its original state, and even the battery life was worse than before. Do you think adding water can make the entire battery group "renewed"? It's simply a fantasy! It's like giving an elderly person an injection to boost their vitality. It can temporarily extend their life, but attempting to reverse aging is ultimately in vain.

Common scams related to battery repair
1."Exchange old for new", temporarily matching voltage
Some repair shops will help you find an old battery with a voltage close to the normal range to replace the poorest one in the group. This may seem like a "resurrection", but in fact, it ignores the irreversible sulfation damage of lead-acid batteries, and the root problem remains unsolved.

2. Add "Magical Repair Solution" and use "High-tech Repair Device"
Some sellers of potions and equipment will only tell you how simple the operation is: "One plus one repair, immediate results!" But what about the truth? A few days after refilling, the battery performance dropped sharply. Due to the battery being disassembled, the pressure relief valve was damaged, resulting in scrapping. When inspected at another store, he was directly sentenced to death. Final result: The old battery loses its discount value for trade-in. Not only did you waste the money spent on repair, but you also have to pay extra for a new battery!

Where do the used batteries go?



Many people think that so many old batteries in the market would be refurbished andresold. In fact, the vast maiority of used batteries are directly dismantled to recover themetals. The reason is simple: refurbishing is costly and the profit is thin, which is far lessprofitable than selling the metals directly.
So, anyone who boasts of being able to "restore as new" is merely eyeing your wallet
