Can the battery still be used if it shows white?

Can the battery still be used if it shows white? The following are specific details about the battery: 1. Reason: The white crystals are caused by a chemical reaction due to slight leakage of the electrolyte. You can wash them off with hot water, and the battery can continue to be used. 2. Battery indicator: The battery charge indicator, also known as the "eye," shows black when charging is needed, green when the battery is in good condition. If it shows black, the battery needs to be recharged, as it has already experienced over-discharge. The charging capacity from the car itself is insufficient, and a charger must be used to recharge the battery. It takes 20 hours to charge a car starting battery.
I've driven for many years and encountered the white indicator in the battery inspection window several times. That white color is not a good sign—it usually indicates the electrolyte level is too low or there's an internal issue, meaning the battery is nearing the end of its lifespan. Can you still use it? It's better not to, as it might fail at a critical moment, like when you urgently need to start the engine, especially in cold weather or after prolonged inactivity. Based on experience, car batteries typically last 2-5 years, and driving habits play a big role. Frequent short trips without running the engine can prevent the battery from fully charging, accelerating aging. I recommend replacing it with a new battery to avoid trouble—just make sure to choose the correct model for your car and follow safety precautions during installation to prevent short circuits. Regular checks can save you both money and hassle.
I've personally repaired many cars and am very familiar with battery conditions. A white display usually indicates insufficient fluid levels or internal defects, meaning the battery is basically dead. Can it still be used temporarily? It's better not to, as the risk is too high—it could fail to start at any moment. If you insist on using it, you'll likely notice delayed starts and flickering headlights. If the engine stalls while driving, it could be dangerous. It's recommended to replace it immediately without delay. Regular maintenance is simple: clean the battery terminals monthly to prevent corrosion, and for refillable batteries, top up with distilled water quarterly to extend their lifespan. Battery issues can easily affect the entire car system, including the air conditioning and lighting, so address them early to avoid being stranded on the roadside.
