How long is the general service life of a car battery?

The service life of car battery normally is 1 ~ 8 years, and has a lot to do with the case of vehicle. If the vehicle generator has normal back-out electricity, no electrical leakage iron base, it can use for more than 3 years.

The storage battery role

When preparing for a vehicle, the battery discharge to the starter, and by the starter drive the flywheel, crankshaft, and launch vehicles. The engine power supply is insufficient or did not start the car with electric power source such as a sound system, lighting system, when the engine start after the normal power supply, battery will collect and store electricity, for later use.

Car battery can be roughly divided into and ordinary and maintenance-free battery (not free maintenance).

We are all familiar with the basic is ordinary passenger car use battery storage battery and maintenance-free battery, two classes. Sales on the market at present most of the models are adopted and maintenance-free battery, and the majority of Japanese, use the free maintenance battery, also is the common battery.

Ordinary battery, also known as lead-acid battery, the electrode is made up of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. The main advantage is that the voltage stability, the price is cheap; The disadvantage is that frequent daily maintenance. Old-fashioned common battery life in 2 years, and to periodically check the height of the electrolyte and add distilled water.

The greatest characteristic of maintenance free storage battery, just as its name implies is "free maintenance. Within the service life of the basic don't need to add distilled water. It also has a shock resistant, high temperature resistant, small volume, the characteristics of uniformity .Relatively, of course, it also is more expensive than ordinary battery. As for the service life, maintenance free storage battery normally suggests replacement cycle for 3 years or so.

From the Angle of the car battery to use and maintenance, whether your car is filled with battery or ordinary and maintenance-free battery, the normal service life is around 2 to 3 years.As for want to prolong service life, ordinary batteries can be used for 3 years or so after adding electrolyte, thus prolonging the life of the 1 to 2 years, as for the maintenance free storage battery, it still directly changed, basic have no repair.

How to check the battery myself: cold car voltage is 12 v in the above.

Although the service life of the battery is generally around 2 to 3 years, but before its failure or die basic won't appear obvious symptoms of early performance may be directly overnight after launch vehicle is not smooth or is not electric power storage battery, serious when can appear even when the red light vehicle flameout. If these failures appear in the archives mouths you just want to use it, it would be in trouble. So how to check the battery at ordinary times is also crucial.

Battery check main use two data, the first is the voltage, the second is the starting current. Check and preferably under cold state (overnight).The voltage value must be higher than 12 v, if less than 12 v means that you can prepare and the battery to say goodbye. Voltage check, the owner friends can DIY, use a multi-meter, is built in battery is negative.

In general, a car battery service life for many young specific as follows:

Car battery service life is normal in 2 to 3 years.

The car battery can be divided into two kinds. One is maintenance-free battery, the other is common battery.

Ordinary battery is also known as lead-acid battery. The main advantages of this kind of battery are cheap, relatively stable voltage. Weakness is also evident that require frequent maintenance. Need to regularly check the height of the electrolyte and add distilled water.

Maintenance free storage battery: In life do not need to check the height of the electrolyte and add distilled water. At the same time also has small volume, high temperature resistant, resistant to shock a lot of advantage. The battery, after all, is simple and convenient. Weakness is more expensive than ordinary batteries.

Want to increase the service life of the battery, you must pay attention to the usual maintenance and care for, don't hurt the battery car habit. Battery life will soon expire generally feel bright headlights didn't before, or the car can't type fire while it was colder. If there is a similar situation will check whether I should change the battery.

Now the car battery can be roughly divided into and ordinary and maintenance-free battery (not free maintenance).Sales on the market at present most of the models are adopted and maintenance-free battery, and the majority of Japanese, use the free maintenance battery, also is the common battery.

Ordinary battery, also known as lead-acid battery, the electrode is made up of lead and lead oxide, the electrolyte is sulfuric acid aqueous solution. The main advantage is that the voltage stability, the price is cheap; The disadvantage is that frequent daily maintenance. Old-fashioned common battery life in 2 years, and to periodically check the height of the electrolyte and add distilled water.

The greatest characteristic of maintenance free storage battery is "free maintenance". Within the service life basically, don't need to add distilled water. It also has a shock resistant, high temperature resistant, small volume and uniformity. Relatively, of course, it also is more expensive than ordinary battery. As for the service life, maintenance free storage battery normally suggests replacement cycle for 3 years or so.
