Is Battery Restoration Reliable?

Some failed batteries can be restored by adding restoration fluid, while others with severe issues are beyond repair and must be scrapped. Below is an introduction to battery restoration fluid: Functions of Battery Restoration Fluid: Battery restoration fluid, also known as lead-acid battery restoration 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 is simple and easy to operate without requiring professional restoration equipment. Due to the different compositions of restoration fluids, their effectiveness varies. Adding Battery Restoration Fluid: After adding battery restoration fluid, the battery undergoes a 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 its lifespan by approximately one year.
I've been driving for over 30 years and have seen plenty of money-saving tricks. When I was younger, I thought battery restoration could extend lifespan—tried adding electrolyte and tinkering with old batteries using reconditioning chargers. The result? Mostly wasted money. Once a battery ages internally, it's irreversible. Like that one time when a 'repaired' battery lasted two extra months before dying mid-drive. Had a close call once when headlights suddenly failed at night due to a restored battery failing—almost hit the guardrail. Learned my lesson: normal battery lifespan is 3-5 years. Rather than risky repairs, it's smarter to replace with new branded products—far safer and more reliable. After all, vehicle power affects ignition and lighting. If a shady repair leaves you stranded on the highway, the tow truck fee alone would cost more than a new battery. Just not worth it.
