LV ELECTRICAL SYSTEM 4 2. BATTERY SPECIFICATION System Voltage : 12 Volts (-ve earth) Battery : 12V DIN 44 40 Ah 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 or broken alternator belt, 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 and alternator. Check the alternator belt for cracks and retention, if slipping. 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.
