How to Add Battery Repair Fluid?

Non-metallic tools such as syringes or plastic funnels. Open the vent valve of the lead-acid battery. Vent valves can generally be divided into two types: one is the pry-open type, which requires a sharp tool to pry open, and the other is the screw-open type. Add the repair fluid to the battery vent hole according to the specified dosage. If the battery is severely dehydrated, after adding the repair fluid, you also need to add replenishment fluid to the battery separator. Install the battery vent cover and let it stand for 2 hours before the battery can be used. The longer the standing time, the better the repair effect will be.
I've been repairing cars for over 20 years, and handling battery fluid replenishment is simple but requires caution. The battery must be of the refillable type—don't waste effort on sealed ones. First, turn off the engine and wear thick gloves and goggles to prevent acid splashes. Check that the battery top is clean and dust-free, wiping it with a damp cloth if needed. Gently twist open the caps—don't yank them. The fluid level is usually below the indicator line; just add distilled water or specialized replenishment fluid, avoiding overfilling. Use a small funnel for precise pouring. After refilling, securely tighten the caps and start the engine, letting it idle for 10 minutes to recharge the battery. Finally, check if the voltage stabilizes. Safety is paramount—the acid is hazardous and can burn skin. Remember, this isn't a perfect fix; replace aged batteries instead. Quarterly maintenance can extend battery life, saving frequent hassle.
My spouse's car keeps having issues, and the battery fluid needs frequent top-ups. The steps are simple but must be done carefully. First, confirm the battery is serviceable—most new cars have maintenance-free ones, so don’t mess with those. Prepare some distilled water; don’t use tap water, as it can cause scaling and damage the battery. Wear rubber gloves to protect your hands and use a cloth to clean around the caps. Slowly unscrew each cap—don’t force it or risk breaking them. If the fluid is low, pour in water bit by bit, not too quickly, until the level reaches the marked line. Once done, tighten the caps securely and drive the car for a while to recharge the battery. My son once messed up and caused a leak, making a huge mess—ever since then, I always remind everyone to be meticulous. Check the fluid level regularly, especially in summer when high temperatures speed up evaporation. If unsure, take it to a shop and let a professional handle it—safety first.
As a new driver, I encountered battery issues and decided to add repair fluid myself. First, check the manual to confirm the battery type, as not all are suitable. Disconnect the negative terminal before operation to reduce risks, and wear gloves and goggles for protection. Clean the battery top before opening, and unscrew the small caps one by one carefully. Use distilled water or repair fluid poured through a funnel, avoiding overfilling—stop when the liquid reaches the indicator line. Secure the caps, reconnect the terminals, and start the engine to charge. My first attempt was clumsy; I spilled acid and nearly got hurt. After learning, I realized the importance of patience and following steps. I recommend beginners use small tools like measuring cups for better control. Regular checks can prevent major issues—it's a practical skill to have.
