Car battery


Servicing and maintaining a car battery should part of a routine vehicle maintenance regiment to keep the battery performing at its best. Sooner or later all batteries have to be replaced, and excessive heat and overcharging are the two main reasons for shortened battery life. Heat causes battery fluid to evaporate, thus damaging the internal structure of the battery. A malfunctioning component in the charging system, usually the voltage regulator, allows too high of a charging rate, leading to slow death for a battery. Colder temperatures increase the thickness of the engine oil, making the engine harder to turn over and the battery work harder, leading to harder starting.


When the car is brought into a service centre, the auto technician should perform a comprehensive vehicle inspection. An important part of the vehicle inspection is to check the performance of the battery. A hand held battery tester only takes a minute or two to check the battery's performance.


In most cases a battery doesn’t go bad overnight. Checking the battery's performance will often indicate if a battery isn’t putting out the amount of amperage that it should and recommend that the battery be replaced. This test should be performed every time the car is brought in for service. Performing a routine battery test will help insure that the vehicle will start each and every time.


To get the most life out of a battery, we suggest five simple tips:

  1. Be sure the electrical system is charging at the correct rate; overcharging can damage a battery as much as undercharging.
  2. If your battery is the type that needs to be topped off, check it regularly, especially in hot weather. Top up with distilled water when necessary.
  3. Keep the top of the battery clean. Dirt becomes a conductor, which drains battery power. Further, as corrosion accumulates on battery terminals it becomes an insulator, inhibiting current flow. To prevent residue from building up, you can use petroleum jelly on the terminals of the battery. This is usually the root cause for all car ignition problems. If you find any bluish green or white powdery layers forming around the battery terminals, then you have to take certain necessary steps to remove it or it will cause additional damages.
  4. When you have stopped your car en route to your destination, you should avoid keeping car headlights and other lights on for a long period of time. This will definitely drain your battery. Also, when the air conditioning unit in your vehicle is not required, it is best to switch it off to conserve power. If your vehicle is using a weak battery, try restraining from unnecessary honking. All these electronic components in your car will be draining on your battery bank thus sending its charge level into a low state. When a lead acid battery is discharged to a very low level, it is almost impossible to bring it back to its maximum power efficiency.
  5. If your car battery needs to be replaced, always replace it with one that’s rated at least as high as the one originally specified by the car manufacturer.

Always remember, that in case you car stalls on the road, firstly turn off all the electricals in your car like the air conditioner, headlamps, roll up the power windows, et al, before finally turning off the car. Similarly, keep all the electrical turned off before turning the car ignition back on. This well help prevent severe voltage fluctuations and prevent blowing a fuse. It will also conserve some amount of charge in the battery and make it last longer.
