Is Chaowei Battery Repair Fluid Effective?
2 Answers
Electric vehicle battery repair fluid does have some effect, but the results after repair are not ideal, it can only extend usage for a period of time. 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 lifespan, and improve various battery performances. It does not require professional repair equipment and is simple to operate. Due to the different compositions of repair fluids, their repair effects also vary. How to Use Battery Repair Fluid: After adding battery repair fluid, the battery undergoes one complete charge-discharge cycle, and its capacity is restored, increasing the travel distance by 5-15 kilometers. After seven complete charge-discharge cycles, the battery capacity can be restored to over 90%, extending the lifespan by about one year. All batteries will experience various faults and failures after reaching a certain lifespan limit.
I tried the Chaowei battery repair fluid last year, and the effect was quite mediocre. My car battery was old and kept failing to start. I heard this product could restore performance, so I spent a few dozen yuan to buy a bottle and give it a try. The operation wasn't difficult—just follow the instructions to add it in. After waiting a few days, the startup did become smoother, but it only lasted for a little over two months before the old problem returned. I think it's suitable for batteries that aren't completely dead, like those with slight sulfation or low fluid levels, but if your battery has aged too much, it's basically beyond saving. It does save money, but in the long run, it's less hassle to just replace the battery outright. Also, be careful about safety—avoid electric leakage or spilling acid everywhere, and always wash your hands after use. In short, it's just a temporary emergency fix; don't expect it to last too long.
