Notes on replacing new batteries for automotive

Batteries are one of the parts plays an important role in the operation of automobiles. Assumes the role of energy storage, run the auxiliary equipment such as radios, air conditioners, lighting ... the engine not running. And more importantly Batteries provide power for the device startup, the ignition system to help start the engine. In addition, it also serves as the power supply in case of load using flow exceed the rated current of the generator.

After launch and big enough rpm, the equipment on the cars will use electricity generated from the generator. Also, the battery is charged to store energy for subsequent reboots.


Most of the batteries used in cars is the battery lead. They are divided into categories such as open batteries (battery water) and sealed storage battery (or dry batteries). Type of battery maintenance as water can refill while dry batteries without maintenance and disposable until empty.



When purchasing or replacing new battery, vehicle owners should note the following issues:

1. Capacity of batteries
The first parameter is regardless of battery capacity. Capacity is measured in units of Ah and therefore knowable storage batteries is how much power. More precisely said temperature is 27 degrees C, power supply batteries for 20 hours before the voltage in each battery compartment down to 1.75 Volt (V).

Refer to the manual car or based on old batteries. If necessary battery of high capacity batteries than older refer to agency guidelines battery. Because the maximum size depends on the capacity of the generator and not based on the brightness of the lights. If the vehicle's electrical system voltage of 12 V just that we use batteries of heavy trucks with 24 V voltage, it will damage the system. So, to choose the right battery voltage to provide matching car.
