Battery Definition Battery is chemical substance whose reaction could produce electricity. Based on the nature of the reaction, there are two types of battery: primary battery and secondary battery. Primary battery is disposable due to its one way reaction. "Dry Cell" ABC and National are the examples of this kind of battery. Secondary battery is rechargeable due to its reversible chemical reaction. The examples of this kind of battery are cell phone and automobile battery. Types of Battery based on materials - "Primary Battery" Lead Acid Battery Lead acid battery uses lead and sulfuric acid as electrolyte solution. Lead Acid Battery Classification based on usage characteristic: SLI : "STARTING", "LIGTHING", "IGNITION" MOTIVE POWER : for electricity powered machineries such as automobiles, forklift, etc INDUSTRIAL : for industrial use such as power company back up, telecommunication etc DEEP CYCLE : for machineries with specific characteristic such as train locomotive, photo voltaic system, etc Types of Lead Acid Battery: Based on the performance and maintenance level, there are four types of lead acid battery: Conventional, Hybrid, Flooded Maintenance Free and AGM Maintenance Free FLOODED MAINTENANCE FREE Maintenance Free Battery The concept of Maintenance Free (MF) emphasizes on minimizing the loss of water within the battery to eliminate the need to add water during the life of the battery. The characteristic of Maintenance Free battery is that it required no water addition. High cranking and endurance level is also one of its distinctive traits, as well as a seal to prevent leaking. All this translate to high reliability. Preventive & Emergency Action Lead acid battery contains explosive hydrogen gas and sulfuric acid which could incur burn injury. To prevent such injury, please apply the following guidelines when working with a battery: Prevention: To prevent facial injury, please wear a protective mask or glasses. Plastic gloves and work uniform will protect your hands and body. Do not smoking and ensure there isn’t sparks of flame near the battery. Finally, keep the battery out of the children’s reach. Emergency Action: In case of accident while working with a battery, apply first aid. If battery liquid was spilled into the eyes, clean them with water for a couple of minutes and consult a doctor. If the liquid was splattered over the skin, wash it with running water and consult a doctor. If the acid was drunk, drink water or milk as much as possible and don’t vomit. In any case, call or consult paramedics or a doctor. Storage & Handling Don’t turn it upside down Even with the presence of a seal, electrolyte liquid still could seep from the crevice when the battery is upside down. Keep it in a cool environment A battery is an active material. The higher the temperature, the faster it self discharge. To prevent such condition, keep the battery in a cool environment. Apply the “First In First Out” (FIFO) Storage System Battery sales or delivery could benefit from FIFO system. If the stocks rotation is well managed, battery recharge is not required. |
