How Much Battery Repair Fluid Is Most Appropriate to Add?
2 Answers
Adding 8 to 10ML of battery repair fluid is quite appropriate. Scope of Application for Battery Repair Fluid: Some failed batteries can be repaired by adding repair fluid, while others with severe issues may need to be scrapped. According to the national standard for electric vehicle batteries (JB/T10262-2001), batteries with a capacity below 70% of the nominal capacity are considered failed. Introduction to Battery Repair Fluid: Battery repair fluid, also known as lead-acid battery repair fluid, battery activator, or battery capacity enhancer, is a solution added to failed electric vehicle batteries. It can restore battery capacity, extend battery life, and improve various battery performances. It does not require professional repair equipment and is simple and easy to operate. Due to the different compositions of repair fluids, their repair effects also vary.
Having driven for decades, the appropriate amount of battery reconditioning fluid depends on the specific situation. Generally speaking, for standard lead-acid batteries, adding about 100-150 milliliters per cell is most appropriate—don't overdo it. First, use tools to open the battery caps and check if the liquid level is between the min and max marks. If it's below min, slowly add the reconditioning fluid, using a syringe or funnel to control the amount, until the liquid level just covers the plates by about one centimeter. After adding, don't rush to drive; instead, connect a charger overnight to activate the fluid for better reconditioning results. Overfilling can easily lead to acid leakage, corroding the battery case, and is also dangerous; too little won't be effective. I recommend regularly checking the battery's health with a multimeter to measure voltage. If the battery is severely aged, it's more hassle-free to just replace it with a new one. In short, be cautious and don't let greed for more cause trouble.
