BATTERY 2. 12V, 40Ah (DIN40RMF) BATTERY CHECKING Using Hydrometer: A hydrometer is a float-type device used to determine the State-of-Charge by measuring the specific gravity of the electrolyte in each cell. It is an accurate way of determining a battery’s Stateof-Charge and weak or dead cells. Visual Inspection: Visually inspect for such as a loose, low electrolyte levels, dirty or wet battery top, corroded or swollen cables, corroded terminals or battery posts, loose hold-down clamps, loose cable terminals, or a leaking or damaged battery case. If the electrolyte levels are low in non-sealed batteries, allow the battery to cool and add only distilled water to the level indicated by the battery manufacturer. PREVENTIVE MAINTENANCE: Tighten loose hold-down clamps and battery • terminals. Check the battery terminals for corrosion (a • white or yellowish powder). To remove it, cover the terminals with a solution of baking soda. It will bubble up and turn brown. When this stops wash it off with plain water. Dry • off the battery with a cloth or paper towel. Coat the terminal with petroleum jelly to prevent • future corrosion. Use a proper wrench to loosen and remove • cables from the terminals. Always disconnect the negative (-ve) cable first • and reconnect it last. Clean the battery terminals with a terminal • cleaning tool or wire brush. Reconnect and tighten the cables, coat the terminals with petroleum jelly. Ensure that battery securely mounted. • If you need to connect the battery to a charger, • disconnect both cables to prevent damage to the vehicle’s electrical system. Clean the battery top. • Check the battery cables for corrosion or • swelling and replace if necessary with equal or larger diameter wire size. CAUTION During normal operation, the battery generates gas, which is explosive in nature, a spark, or open flame can cause the battery to explode causing very serious injuries. Keep all sparks & open flames and smoking materials away from the battery. Getting electrolyte in your eyes or on the skin can cause severe burns. Wear protective clothing and a face shield or have a skilled technician to do the battery maintenance. The battery contains sulphuric acid (electrolyte) which is poisonous and highly corrosive in nature. LV SYSTEM 5
