Can dry batteries be replenished with supplementary fluid?

Dry batteries cannot be replenished with supplementary fluid. Automotive batteries are mainly divided into three categories: lead-acid batteries, dry-charged batteries, and maintenance-free batteries. The car ignition time should not exceed 3 seconds. If the engine fails to start the first time, do not repeatedly attempt to ignite it. Instead, wait for a 15-second interval before trying again. Otherwise, the car battery will frequently supply a very strong current to the starter, leading to its own wear and tear. Car batteries, also known as storage batteries, are a type of battery that works by converting chemical energy into electrical energy. They are primarily made of lead and its oxides, with the electrolyte being a sulfuric acid solution.
Dry batteries actually come in many types, such as AGM or gel batteries. They are all designed with a sealed structure, just like a small enclosed box, where the electrolyte is fixed within the internal materials and absolutely no liquid needs to be added. If you forcibly pry it open to add supplementary liquid, you may damage the sealing strip, causing the acidic liquid inside to leak out. This not only corrodes car parts but may also produce harmful gases, which is extremely dangerous. Once, when I checked a friend's car, I found the battery was dry with very low voltage. I initially thought of adding something, but after professional tool testing, it was confirmed to be internal aging and needed replacement. Instead of risking adding liquid, it's safer and more reliable to buy a matching new battery. Remember, for maintenance-free dry batteries, the only repair is direct replacement—don't try to save money and invite disaster.
