Is Lead-Acid Battery Repair Solution Effective?

Some failed batteries can be repaired by adding lead-acid battery repair solution, while others not only cannot be repaired but may even worsen the problem. Here is relevant information about lead-acid battery repair: 1. Introduction to Battery Repair: Battery repair refers to the general term for repairing secondary rechargeable batteries with declining performance or failure through physical or chemical means. Repair can restore battery capacity, extend battery life, and improve various battery performances. 2. Lead-Acid Battery: A lead-acid battery consists of positive plate groups, negative plate groups, electrolyte, and a container. During charging, the lead sulfate on the plates of a lead-acid battery turns into spongy lead and lead oxide, respectively, with the sulfate ions fixed in them released into the electrolyte, increasing the sulfuric acid concentration in the electrolyte continuously. Conversely, during discharge, the lead oxide in the anode and the spongy lead on the cathode plate react with the sulfuric acid in the electrolyte to form lead sulfate, while the sulfuric acid concentration in the electrolyte continuously decreases. When a lead-acid battery is undercharged, the lead sulfate on the cathode and anode plates cannot be completely converted into spongy lead and lead oxide. Long-term undercharging can lead to lead sulfate crystallization, causing plate sulfidation and deteriorating battery quality. Conversely, if the battery is overcharged, the amount of oxygen produced at the anode exceeds the adsorption capacity of the cathode, increasing the internal pressure of the battery, causing gas overflow, reducing the electrolyte, and possibly leading to softening or shedding of the active material, significantly shortening the battery's lifespan.
I've been driving for over 30 years and have used lead-acid battery restoration fluid several times. To be honest, it does help a bit, especially when the battery only has minor surface sulfation. Adding it might recover some charge temporarily, buying you an extra month or so. I remember one winter during heavy snowfall when my old car had trouble starting. After inspection, I found lead sulfate crystals had built up on the plates. I added a bottle of restoration fluid and barely managed to start the engine the next day. But don't think it can solve serious issues - if there's internal short-circuiting or severe plate wear, the restoration fluid won't help at all, and you'll have to replace the battery. This stuff is cheap and convenient, so there's no harm in trying, but don't rely on it. Regularly checking your battery's voltage and overall condition is more important - safety first, after all. From my experience, most old batteries will eventually need replacing to avoid being stranded on the road.
