The purpose of the battery is to supply the necessary current to the starter motor and the ignition system while cranking to start the engine. Traditionally, this is called an SLI, for Starting, Lighting, Ignition, and its main purpose is to start the engine. Once the engine is running, power for the car is supplied by the alternator.
Battery that contain unformed plates, filled with sulfuric acid and charged.
An ampere hour (abbreviated AH, or sometimes amp hour) is the amount of energy charge in a battery that will allow one ampere of current to flow for one hour. An ampere is a unit of measure of the rate of electron flow or current in an electrical conductor.
It is consists of strong plastic container that contain positive and negative lead plates, separators and battery acid.
It is the number of minutes a battery can sustain some voltage under a 25 ampere discharge. This is very important as it provides emergency power such as for ignition, lights and so on. The higher the minute rating, the higher the chance for the car to run for a longer period before recharging is needed.
Cold Cranking Amperes (CCA) is a rating to show how much current can a battery produced to the starter motor for a particular time.
Refer to vehicle’s manual for battery group size and minimum rating. Or else, look up for the vehicle models and year in battery application guide. Take note for the group size and rating. Do not use lower one than your car rating. Instead, higher rating can provide longer battery life, especially in starting an older car.
Terminals and vent plugs need to be clean. Explosion may occur if the vent plug is blocked. Pay attention to the water level of each cell and fill up with distilled water or battery water when necessary, without over filling. Do not use polluted water because it can ruin the power and the battery life.
Since it is maintenance free, it is made without adding distilled water for the period of the warranty and as long the environment is suitable. In case for hotter region area, this may weaken the battery life due to gas release. Have battery heat shields installed to keep the battery temperature down as well as avoiding parking under the sun.
Whether they are charged or not, it must be handle carefully to avoid any explosion due to sulphuric acid. When the battery is charged, it must be done in well-ventilated area. The red positive lead is connected to the positive terminal and black negative lead to the negative terminal. Before and after charged, make sure the charger connection to the lead is off to avoid sparks. Do not charged a damaged or frozen battery. Plus, prolong the charging is prohibited.
Some of the examples are slow in igniting the motor; quick power loss; headlights are dim-lit; battery discharged indication for some time even after the engine is on, and etc.
The lifespan differs from the perspective of vehicle, region, and driving patterns. A normal lead acid battery will up to 18-36 months.
Each cell of a lead storage battery contained plates of lead (cathode) and lead coated with lead dioxide (anode). Through chemical reaction, the electrons flows through the conductor to produce electricity.
The function of the battery is important to supply current to the starter motor and ignition while turning on the engine. Plus, it provide extra current when the demand is higher than the alternator can provide and act as an electrical storage.
