How to Repair a Broken Battery Cell?
2 Answers
Battery cell repair: For a battery with a broken cell, the problematic single cell can be extracted and replaced. After replacement, seal it with sealing adhesive, weld the terminals, add electrolyte, and finally charge it. Those with the capability can attempt the repair themselves, but it's best to seek professional help at a repair shop. Causes of battery cell breakage: 1. Poor battery quality. 2. Incorrect usage leading to internal short circuits. 3. Frequent use of the battery. 4. Severe impacts or drops. The battery is a crucial component in a car, but it is also a wear-prone part. Typically, a battery's lifespan is around 2-3 years, and proper usage can effectively extend its service life. When the car is turned off, avoid prolonged use of electronic devices inside the car, and it's also recommended not to use the air conditioning or headlights, as this can shorten the battery's lifespan.
I've encountered quite a few cases of battery cell failure, mainly caused by a damaged internal cell or connection break. Aging, over-discharging, or physical impacts are the most common culprits. Repair requires professional tools: first use a multimeter to test battery voltage. If total voltage drops below 10V or any single cell shows zero voltage, try adding distilled water or electrolyte, shake well and recharge. If unrecoverable, specialized welding equipment is needed to repair broken connections or replace the cell - but this is risky as battery acid may splash and cause injury. Generally not DIY-friendly; safer to visit repair shops who have professional equipment to test battery internals and assess repairability or recommend replacement. Regular battery health checks are advised for long-term drivers to prevent cell failures.
