The Frequently Asked Questions About CAR BATTERY
1.HOW DO I KNOW MY BATTERY IS DEAD (OR ABOUT TO DEAD)?
Slow Engine Crank: When you attempt to start the vehicle, the cranking of the engine is weak and takes longer than normal to start.
You have Jumped start your car a Lot: If you have to jump your car more than three times in a single week, it’s time to replace your battery.
2.WHAT CAUSES A CAR BATTERY TO DRAIN WHEN THE CAR IS OFF?
There are some devices on your car that are supposed to go to sleep when it’s parked, and sometimes, not all of them go to sleep.
Interior Electrical Systems Current Leak: Most vehicles draw some battery current when the key is off, example clock and the internal memory of engine computers, body-control modules and radio presets. All these together draw a very small amount of current. Fifty milliamps would be a safe upper limit for this, although many vehicles will draw less. If you’re not sure, look up the correct rating in the service manual.
Defective Alternator Diode: An alternator recharges the battery and powers certain electrical systems. If your alternator has a bad diode, your battery can drain. The bad diode can cause the circuit to charge even when the engine is shut off, and the car won’t start in the morning.
2.WHAT CAUSES CAR BATTERY TO DIE QUICKLY?
Too Many Short Drives: If you are always taking short drives, this may be the causing your battery life to end too soon. If you keep on starting and stopping your car before your alternator has time to recharge, this would account for the reason why your car battery keeps dying and isn’t last as long as it should.
Faulty Charging System: The battery is charged by an alternator(driven by a belt from the engine). If there is something wrong with the system, your car battery could be dying too soon.
Extreme Hot Temperatures: Hot weather can drain the life out of your car’s battery. Build-up of lead sulfate crystals can occur when leaving your vehicle in high temperature for too long.The sulfate build-up can shorten the life of your battery and increase the amount of time it needs to be recharged.
Vibration: Vibrations from rough travel or a poorly-secured battery can shake loose or damage the plates.
3.WHAT IS A CHARGING SYSTEM?(ALTERNATOR)
The charging system is to maintain the charge in the battery, and to provide the main source of electrical energy while the engine is running.
If the charging system stopped working, the battery’s charge would soon be depleted. If the battery is weak and the alternator is not working, the engine may not have enough electrical current to fire the spark plugs, so the engine will stop running.
The main component in the charging system is the ALTERNATOR.
The alternator is driven by a belt that is powered by the rotation of the engine. This belt goes around a pulley connected to the front of the engine’s crankshaft and is usually responsible for driving a number of other components including the water pump, power steering pump and air conditioning compressor.
4.HOW TO TEST MY ALTERNATOR?
Connect the meter leads to the battery terminals and look for 13.5 to 14 volts (engine running, lights and accessories off). That means the alternator is charging the battery. While lights and accessories are turned on will be 13 to 13.9 volts.

An car battery is a rechargeable battery that arrangements electrical imperativeness to a motor vehicle. Once the engine is running, control for the auto’s electrical structures is given by the alternator.
And furthermore starting the engine a SLI battery supplies the extra power imperative when the vehicle’s electrical requirements outperform the supply from the charging structure. It is also a stabilizer, evening out potentially hurting voltage spikes. While the engine is running, most of the power is given by the alternator, which consolidates a voltage controller to keep the yield in the region of 13.5 and 14.5 V.
Battery electric vehicles are controlled by a high-voltage electric vehicle battery, notwithstanding they as a general rule have an auto battery as well, with the objective that they can use standard auto embellishments which are expected to continue running on 12 V. – Car Battery Delivery Malaysia

Early cars did not have batteries, as their electrical systems were confined. A toll was used as opposed to an electric horn, headlights were gas-powered, and the engine was started with a torque. Auto batteries ended up being for the most part used around 1920 as cars twisted up obviously outfitted with electric starters. The settled battery, which did not require refilling, was planned in 1971.

Low-upkeep or bolster free: beforehand, batteries required upkeep as electrolyte refills. Display day batteries hold their fluid for the life of the battery. A deficiency of these batteries is that they are to a great degree narrow-minded of a significant discharge, for example when the auto battery is completely drained by leaving the lights on. This coats the lead plate anodes with sulfate stores and can diminish the battery’s future by a third or more.
VRLA: generally called held glass tangle (AGM) batteries are more tolerant of significant discharge, yet are more costly.
Batteries are ordinarily made of six galvanic cells in a game plan circuit. Each cell gives 2.1 volts to a whole of 12.6 volts at full charge. Every cell of a lead accumulating battery involves trade plates of lead (cathode) and lead secured with lead dioxide (anode) soaked in an electrolyte of sulfuric destructive arrangement. The certifiable standard cell potential is obtained from the standard decreasing conceivable outcomes. This causes a manufactured reaction that releases electrons, empowering them to travel through transports to make control. As the battery discharges, the destructive of the electrolyte reacts with the materials of the plates, changing their surface to lead sulfate. Exactly when the battery is restored, the compound reaction is pivoted: the lead sulfate changes into lead dioxide. With the plates restored to their one of a kind condition, the technique may be reiterated.
A couple of vehicles use other starter batteries. the 2010 Porsche 911 GT3 RS has a lithium-molecule battery as a contrasting option to save weight. Overwhelming vehicles may have two batteries in plan for a 24 V system or may have course of action parallel get-togethers of batteries giving 24 V.
Physical plan: batteries are gathered by physical size, sort and position of the terminals, and mounting style.
Ampere-hours (A·h) is a unit related to the essentialness storing point of confinement of the battery. This rating is required by law in Europe.
Twisting amperes (CA): the measure of current a battery can give at 32 °F (0 °C).
Frigid turning amperes (CCA) is the measure of current a battery can give at 0 °F (−18 °C). Give day cars PC controlled fuel-implanted engines take near two or three minutes to start and CCA figures are less basic than they were in the seasons of carburetors.
Hot turning amperes (HCA) is the measure of current a battery can give at 80 °F (26.7 °C). The rating is described as the current a lead-destructive battery at that temperature can pass on for 30 seconds and keep up no under 1.2 volts for every cell (7.2 volts for a 12-volt battery).
Hold restrain minutes (RCM) is a battery’s ability to keep up a base communicated electrical load; it is portrayed as the time (in minutes) that a lead-destructive battery at 80 °F (27 °C) will reliably pass on 25 amperes before its voltage plunges under 10.5 volts.
Battery Council International get-together size (BCI) shows a battery’s physical estimations, for instance, length, width, and stature. These social occasions are managed by the organization.
In the United States there are codes on batteries to empower customers to buy a starting late conveyed one. Right when batteries are secured, they can start losing their charge. A battery made in October 2015 will have a numeric code of 10-5 or an alphanumeric code of K-5. “An” is for January, “B” is for February, and so forth (the letter “I” is skipped).
