When replace car battery-7 signals you should know

For most car owners, the car battery is probably one of the most overlooked components. However, this silent ‘hero’ plays a vital role in starting and running your car. Just as the human body is inseparable from the heart, the car is also inseparable from the normal operation of the battery. 

When the engine is running, the generator supplies power to the car's electrical system and charges the battery. When the engine is starting or running at low speed, the generator is not generating power or the voltage is very low, and the battery supplies power to the starter and the car's electrical system. How to determine whether to replace car battery is a basic skill that every car owner should have.

In this article, we will introduce the steps to determine whether the car battery needs to be replaced, to help car owners to better maintain and replace car battery.

1. 7 signals whether need to replace car battery

① The car is more difficult to start than usual

In the absence of other factors, if you suddenly find that the car is difficult to start, it may be a precursor to the impending retirement of the battery. Of course there is another situation in winter, the so-called winter cold start difficulties. It all depends on whether your car is new or has almost reached the end of its battery life.

② Darkening of the idle speed

For example, when waiting for a red light or stopping temporarily, your car's headlights suddenly dim. Idle state, the car headlights by the battery for auxiliary power supply, if you give the throttle, the light is obviously brighter than the idle state, means that the battery storage capacity decline seriously.

③ Battery fault warning light is on

The fault light is a direct reminder that something is wrong with the charging system. At this point, you need to go to 4S or repair store to check and replace car battery, the battery is one aspect, there may also be a problem with the generator!

④ Rattling when starting

Due to the battery discharge capacity becomes weak, the starter runs poorly and squeak, this situation is especially obvious in low temperatures, because the cold weather, the battery activity will also be reduced, and after the weather warms up such a situation will improve or disappear, so many owners do not think.

⑤ Observation port change

Many maintenance-free batteries have an observation port, there is a light to show whether the battery is working well, the normal battery is green, need to charge the maintenance is black, white means that the life of the need to replace car battery.

But look at the electric eye judgment can only be used as a reference, a lot of batteries, with 5 years, or green, but not charged into the power.

⑥ Battery bulging liquid leakage

Mainly observe whether the battery leakage or bulging, if such a situation happened means you should replace car battery in a timely manner, this situation is not only the battery life of the problem, and even about the car battery safety.

⑦ Voltage change before and after starting

The normal car battery voltage is about 12V, and after the start due to generator charging, the voltage will be raised to about 13-14V, many vehicles have voltage detection function, pay attention to the voltage before and after the start is also a good means of determining the battery life, the vehicle does not start below 12V or start below 13V should be considered whether the battery has problems.

2. How to maintain the car battery

From the normal maintenance, the most important thing to pay attention to the battery is to avoid over-discharge, the following situations try to avoid:

① Continue to use electricity after the engine is turned off

Many drivers used to turn off the engine is still in the car to use the car equipment, listen to music, rest, open the lights, and even open the air conditioning, the vehicle's power supply has been completely supplied by the battery.

A large number of power consumption will allow the battery to continue to discharge, the battery can only be maintained for two or three hours at most, this habit of using the car will be a serious loss of battery power.

② Starting the vehicle for a long time or frequently

Every time you start the vehicle, the battery needs to release a portion of the power to drive the engine, too frequent start, is undoubtedly the battery ‘repeated flogging’ . When starting, the ignition time should not be more than 3 seconds; if the start fails, it is recommended to ignite again after an interval of 15 seconds.

③ Prolonged use of electricity after the engine is turned off

After the engine is turned off, the generator of the car suspends its work, and the electric battery becomes the ‘main bearer’ of power supply of the car. If you continue to use electricity for a long time, the battery will be in a state of ‘dry consumption’.

④ Prolonged low battery state

In the case of insufficient power, the specific gravity of the electrolyte of the lead-acid battery will decrease, and the pole plate will gradually fall off, which will eventually lead to damage. In addition, long-term low battery state will also lead to unbalanced charging and discharging of the battery, affecting the performance and life of the battery.

3. Precautions for choosing and replacing batteries

When replacing car battery, regardless of what brand of battery, the battery selection mainly depends on three parameters:

• Car battery types, whether it is an ordinary lead-acid battery, or EFB or AGM.
• Look at the battery AH number and CCA value.
• Size of the battery rack that can fit into the body of the car.

Such as the Tycorun stop start car batteries.

It is a 12v 50AH 600CCA sodium ion battery, and the size is 244*176*190mm. This car battery can provide With a higher energy density and a longer service life, it ensures a fast and reliable start. Also, the price is affordable.

Conclusion

To summarize, a car battery is always a consumable product and it has a lifespan. Generally a car battery life is about 2-3 years, if it comes to the replacement cycle or when your vehicle has the above symptoms, you should go to the workshop in time to check and replace car battery.
