Battery is an important part of the vehicle should not be overlooked. Without a healthy cell, the car will remain stationary. We are responsible for our vehicles they can support how long. In order to extend its life, we need to properly maintain them. Maintenance-free batteries are gradually replacing lead-acid batteries, but it is important to understand the basic principles remain the same. We will discuss all the important aspects of the battery in this article.
How batteries work?
Lead-acid automotive batteries are energy storage device by the stereotype and stereotype dioxide composition. These plates immersed in the electrolyte. Percentage of water was 65%, while 35% of the sulfuric acid solution. When the battery is used to start the car, it will be discharged. Sulfuric acid electrolyte is consumed, the rest of more water. In the charging process, it is returned to the acid sulphate. Battery provides a high starting current required to start the motor vehicle engine. After the engine starts, the battery will be charged again by the charging system of the engine driven. In this process, the alternator to obtain the necessary energy from the rotation of the engine through a belt, to charge the battery. When the engine is running
What causes a low battery?
In summer, when the car is exposed to direct sunlight for a long time, it will accelerate the corrosion process and electrolyte evaporation. This will shorten battery life, making it weaker. Therefore, avoid parking under the appropriate shadow, lest the sun heated car.
Battery must be properly installed, in order to avoid any form of vibration. Over time, the vibration plate vibrates, so that the internal connection is lost. As a result, the battery can not be charged properly.
After starting the car, make sure the driver enough time so that the battery is fully charged again. In the alternator after the engine is started the release of energy, it will take some time to charge the battery. Otherwise, the battery charge will remain inadequate, insufficient to provide high current to start the motor.
When the engine is off, the headlights remain open or music system will consume battery over time. Avoid prolonged into the charger to prevent battery discharge.
Corrosion and other hazards on the battery terminals as harmful to the battery. Be sure to carefully once or twice a month to clean the battery terminals. Make sure to wear gloves and eye protection. Toxic white powder on the terminal, so as not to contact with the skin.
Signs replace the battery:
There are several signs may indicate that your battery is low and needs to be replaced.
After  off the engine, the car's large lantern slightly darker.
When starting  cars, due to the low current supplied by the battery, the starter motor is rotating slowly.
There are some visual indication that the battery needs to be replaced.
 internal short circuit or overcharging can lead to cell expansion. If signs around the battery anywhere muster found, replace the batteries.
 carefully check the battery compartment for damage.
How to start the engine with a weak battery?
We do not recommend the use of a weak battery. However, in an emergency, when you are stuck at the side of the road trip, you can use jumper cables. If you think the battery is not in the highest state, make sure to keep a set of jumper cables in the car. Jumper cables allow you to help another car to quickly start the vehicle. Although this is a very simple technique, but must take security measures to avoid any danger. The following steps will guide you quickly start the vehicle:
 ensure both batteries have the same rated voltage, i.e. 12 V
 the ignition switch of the vehicle parked in the other in an intermediate position close enough to turn it off.
 Do not beat frozen battery. It is easy to explode.
 Wear rubber gloves and safety glasses.
carefully identified and the positive electrode connecting the two batteries.
 ensure not to touch the other end of the body, to avoid any risk of sparking.
 the negative cable clamp on the negative normal cells.
 the negative electrode metal with a weak portion to the other end of the cable car.
 Finally, start the car with the good battery.
 5-7 minutes giving it time to charge a battery that.
start now with a weak battery ignition.
 Remove the cable in the reverse order carefully. First remove negative cable, then remove the positive cable from the car battery well. Finally, remove the positive cable from the automotive battery is weak.
