ELECTRICAL 7 ELECTRICAL 8.3 STARTING AND CHARGING SYSTEM 8.3.1 BATTERY FUNCTION: The battery has three major functions in the electrical system: It is a source of electrical energy for cranking the engine. Once the engine is cranked, it is getting charged from alternator. Also it provides electrical energy to the vehicle loads whenever the alternator output current is not able to meet the demand or when the alternator is fails. SPECIFICATION: 12V, 80 A/H, Specific Gravity: 1.27 ± 0.01 LOCATION: Battery is located in the left side of the engine compartment on panel wheel arch inner LH. BATTERY DO’S AND DON’TS: DO'S: Think Safety First. Do regular inspection and maintenance especially in hot weather. Recharge batteries immediately after discharge. DON'TS: Don't add acid. Don't store batteries with tools and other equipment haphazardly placed. Don't disconnect battery cables while the engine is running (battery acts as a stabilizer). Don't put off recharging batteries. Don't add tap water as it may contain minerals that will contaminate the electrolyte. Doesn’t discharge a battery any deeper than you possibly have to? Don't mix different size and types of batteries. FACTORS AFFECTING BATTERY LIFE: The reasons that most batteries fail prematurely are related to one or more of the following: 1.Improper charging 2.Lack of water 3.Installation 4.Operational issues NOTE: The user has control over most of the conditions that lead to premature failure. 1. IMPROPER CHARGING: Over charging Charging a battery greatly in excess of what is required is harmful in several ways. Under charging A battery operated with insufficient charge over a long period of time may develop a type of sulphate in the plates which is dense, hard and crystalline and which cannot be electrochemically converted to normal active material again. A battery operated in an undercharged condition is unable to deliver the full power intended for it. Constant undercharge results in Sulphation of plates and a running down of cells. This also causes lead sulphate deposits on separators which create a short circuit between positive and negative plates.
