Attempting to repair a dead car battery may sound like an absurd idea to most people, but in some parts of the world, it is not uncommon. A recent video posted on the Facebook page Topspeedgermany offers a glimpse into this unusual practice, showcasing a man who repairs a dead car battery using unconventional methods that are far from safe or recommended.
It is essential to note that tampering with car batteries can be extremely dangerous. Inexperienced individuals may accidentally cause an explosion or burn themselves with the corrosive chemicals inside. Lead exposure is another significant hazard that should not be taken lightly.
However, this video does provide a fascinating tutorial on the internal workings of a typical car battery. These batteries, commonly found in our vehicles, are usually composed of six cells with a total voltage of 13.2 volts when at nominal voltage. Discharging the battery below a certain point for an extended period can lead to the formation of lead sulfate crystals on the plates, reducing the battery’s capacity and conductivity. Various factors such as vibration and physical damage can also affect the battery’s performance.
In the video, the man proceeds to open up the battery by puncturing holes in the lid corresponding to each cell. He then removes the positive terminal and empties the acid from the faulty cell. After conducting a short-circuit test on the remaining cells, he concludes that the faulty cell has been successfully identified. Using a saw blade, he carefully cuts out the damaged cell’s plate assembly and removes the positive plates. He thoroughly cleans the pocket separators, reassembles the intact positive plates, and reconnects them with their negative counterparts.
The most intriguing part of the repair process is the unique soldering technique employed to connect the plates. The man uses a second car battery and a tapered tip connected to one of the terminals as a makeshift soldering iron. By creating a short circuit between the “soldering iron” and a rod of solder, the heat produced from the arc melts the solder and forms the necessary connections.
After reassembling the plate pack, it is placed back into the battery. Although this repair method showcased in the video may seem effective, it is crucial to reiterate that attempting it without proper knowledge and experience is extremely risky.
While this video provides an unconventional insight into the repair of car batteries, it is crucial to prioritize safety and rely on professional expertise when dealing with such complex and potentially hazardous systems.
