FACT OF INVERTER BATTERY: > While discharging, The battery works as galvanic cell! > While charging, The battery works as electrolytic cell! *????* _Why distilled water is used?_ *Since, inverter batteries use Aqueous Diluted Sulfuric acid, the electrolysis uses most of the water to break down in Hydrogen and oxygen.* *⚠️ Why not tap water?* Tap water contains impurities, salts, and minerals (like Ca²⁺, Mg²⁺, Cl⁻, etc.). These can: React with sulfuric acid Deposit on electrodes, reducing battery efficiency Corrode internal parts Shorten battery life
