How to judge the car battery capacity is insufficient?
Storage battery is a device that directly converts chemical energy into electrical energy. It is a rechargeable battery designed to be recharged through a reversible chemical reaction. It usually refers to a lead-acid battery, which is a type of battery. , Belongs to the secondary battery has been widely used in our lives, and has a very important role in our lives, and as a car with a high frequency of daily use, how much do you know about the car? ? Do you know how to judge the capacity of a car battery is insufficient? The editor of Kanglida introduces some small methods to you, I hope it can help you.
We should check the car battery regularly. How can we find that the capacity of the car battery is insufficient? Common methods:
1. Observation window: There is an observation window on the maintenance-free battery. You can judge the quality of the battery by observing the color inside. However, this observation is only a rough judgment based on the density and level of the electrolyte in the battery. It can only determine whether the battery is damaged, but not whether the cold start capacity of the battery is sufficient or whether it can continue to be used. Here we should distinguish the difference between "not bad" and "usable". The observation window shows that the battery that is not bad is not necessarily usable.

2. Tester: How to judge whether the battery can be used normally? I use the battery tester to better detect the starting capacity of the battery, so as to determine whether the battery can be used normally.
3. Multimeter: The use of a multimeter can only check the voltage of the battery. It cannot be used as a capacity test. When some damaged batteries are tested for voltage, the voltage will be 12V. The reason for the damage is not the single cell of the battery, but the pores of the electrode. Blockage causes insufficient capacity, so it does not cause the battery voltage to drop.
4. Time: Whether the battery can continue to be used is judged by the use time, this method is too subjective. Because different owners have different driving habits, and cars with the same usage time also have different vehicle conditions, the battery life will also vary greatly, so this judgment method is also not desirable.
5. Experience: An experienced repairman can judge whether the battery can still be used by the engine speed when starting, but because this judgment is too subjective, the judgment basis cannot be informed to the owner, and the correctness is directly related to the level of the repairman. Cannot be promoted.
The above is the relevant information compiled and compiled by the battery manufacturer Kanglida. I hope it will be helpful to you. If you want to know more information, you can contact us or log in to our official website for more information.
