How To Judge Whether The Battery Needs To Be Replaced?

Dec 12, 2020

1、 It's a voltage measurement. This kind of method is very simple, and the actual effect is the best. Generally, the full load working voltage is about 13V. If the full load working voltage is less than 10V during the inspection, it indicates that the battery must be replaced. Otherwise, it is very likely that the car can not start or start. In addition, there are many automobile systems with battery voltage detection, and the marking value can be used for reference.


2、 Look at the shape. One is to see whether there is a bag around the battery, just like the battery drum on the mobile phone, which means that the service life of the rechargeable battery has already reached the limit and must be replaced. Another is to see if there are milky white or emerald green powder around the bottle. The appearance of this metal oxide represents the long service life of the rechargeable battery.


Look at rated power observation port. Maintenance free batteries can be distinguished according to the power consumption observation port. Green means sufficient power consumption, yellow represents a slight loss, and black represents that the battery must be replaced.

How to better maintain the battery?


When it comes to the maintenance of battery, how should we use it to better maintain it? This travel habit can give you more battery cycles.


Do not listen to music and play central air conditioning after the fire. The battery in the car is a lead-acid battery. Although it is not expensive to install it in a shallow way, the price is not expensive. But if you often use the battery on the explosion-proof switch, it will do great damage to the rechargeable battery. Because the fear of lead-acid battery is to carry out maintenance charge and discharge after a period of application. Therefore, after the fire is off, it is not allowed to listen to music or blow the central air conditioner. It can reasonably increase the number of battery cycles. It is best to charge the battery at any time and maintain full charge.


Make sure you drive a certain number of kilometers


Not driving for a week is not harmful to the battery, but if you don't drive for a long time, the power consumption of the rechargeable battery will be automatically consumed until the rechargeable battery runs out, making the charging battery in the explosion-proof switch for a long time, which is not good for the battery cycle times. 


In addition, if you often drive, but only drive for 2-3 km, it is also harmful to the battery cycle times. Because the battery capacity can not be reasonably filled and the battery is not fully charged for a long time, the vulcanized rubber of the battery pole piece will be made, resulting in inevitable harm. If the car is left for a long time, it is better to pull out the negative level of the rechargeable battery.


There is no need to add too much electrical equipment and household appliances.


Many car buyers remember that there is no need for electricity in the car. If you put it there, you will also leave. Therefore, all kinds of extra household appliances are like home ownership. Electronic dog, traffic recorder, navigation bar, cigarette lighter are not much. 


Some people install inverter power supply, connect power socket, car refrigerator, rice cooker and other household appliances, and refit many charging and discharging machines and equipment, which cause great harm to rechargeable batteries.


It is a very important part of the car to show the driving force for all the electronic products of the car. The service life of the battery is closely related to your travel habits. 


You only need to pay attention to it when you use it at ordinary times. In addition, if your battery power and working voltage decrease, you should also take full account of the harm of temperature, summer can make do with the application, but in winter temperature will reduce the charge and discharge of rechargeable batteries and volume caused a certain harm, before winter remember to check the battery voltage, avoid harm.
