How Much Battery Repair Fluid Is Most Appropriate to Add?

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.

When adding battery restoration fluid, safety comes first—never exceed the recommended amount. Generally, adding about 120 milliliters per battery cell is appropriate, but always refer to the product instructions and your battery model for specifics. Wear gloves and goggles before opening the caps to prevent acid splashes. If the fluid level is too low, add it gradually until it reaches the indicator line and stop. Overfilling may cause excessive internal pressure or even battery rupture, contaminating the engine compartment. After adding, remember to charge the battery for an hour to ensure even distribution of the restoration fluid. Regular maintenance helps prevent deep discharge and extends battery life. If your battery frequently has issues, it’s best to have a professional inspect the entire electrical system for safety.

Add an appropriate amount of replenishing fluid. Generally, add 100-150ml per cell, depending on the battery size and fluid level. Remove the cover to check the fluid level and top up to the standard mark if it's too low. Charge the battery after filling to activate it. Avoid overfilling or underfilling, as regular maintenance ensures better performance and a longer battery life.
