• Do car batteries really need to be replaced regularly?

Many car owners will carry on considering our social question: "How many years can the battery in my car last? Do I need to replace it regularly? Is there a replacement standard that I can check against to determine if the battery is evolving and needs to be replaced on an ongoing basis?"

There are actually two answers to this question, one answer is that there is a standard, what is a standard? Opinions vary and it is common to see so-called manufacturers and the industry less than 80% of the rated capacity for replacement. Or need to be replaced after three years of use. The other answer is that there is no standard, take the feeling and change it when it doesn't feel good. Which approach is more likely? Let's take a look before jumping to conclusions.

The argument that there is a standard

When a new battery is loaded for use, the active substances within it are gradually activated, so performance gradually improves in the early stages of use and eventually reaches an optimal state. This is the time when the battery is in the best health and the most economical to use. But batteries have a long lifespan and can't stay in optimal condition forever. So as we continue to use the battery, under constant charging and discharging, the capacity of the battery begins to decline. There's an argument that after a battery's capacity drops to 80% of its original capacity, performance drops off very quickly, so to make sure your car's battery is always in tip-top shape, it's time for you to consider a new battery.

This argument sounds like it all makes sense, but I still feel like I'm not conducting much research that can guide the meaning of the need for us to live an actual productive car management. It's like eating watermelon, some people only eat the middle part of the sweetest, a piece of watermelon after eating there is still more than half of the red flesh. And some people can nibble on the rind of a watermelon until the green skin is exposed. We students can't say that the second kind of people are greedy, but since the first kind certainly can't waste more time. And the car battery is also because of this, to the teaching capacity of only 80% left to change just like eating melon only eat the sweetest part, the rest you are wasted.

There is no standard, it's just a feeling

Honestly, that's my attitude. I don't care what you say, just use it properly. Tell me the solution when the problem goes wrong. In normal use, there is no rush to change the car if there is no cab for a day, charge it first. Since some appliances may forget to turn off the power or leave it on for a long time resulting in a power failure, charging immediately restores the congestion. If it doesn't work after charging then it really doesn't work and it's not too late to change it.

To say that there are advantages and disadvantages to both methods as well, the first one has the advantage that the battery is always in the best condition and the disadvantage that it is a bit wasteful. It is suitable for people who are demanding of time and efficiency. For example, if you are a big boss, use the time of battery power loss to make money, you can buy a lot of batteries, so you will not worry about the waste of the early, stability is the most important.

And most of us car owners or regular people, there is no harm in living a frugal life. And 80% is a bit of a waste, even with battery power loss we shouldn't waste that time.lithium battery cell machine Also, the probability of a problem with a battery capacity less than 80% is so low that one would actually buy a lottery ticket and maybe win.

But then again, saving is not cheap. This does not mean that we have to use the battery completely before replacing it. After all, it's really a pain in the ass to have a dead and useless battery. So what we mean by economizing is to make the battery as valuable as it can be while still meeting our normal car needs. Therefore, it is very important to correctly determine the health of the battery. Here are some simple methods for you.

1, start the engine obviously feel the starter rotation powerless, and the enterprise recently vehicles have been developing normal work use, not after a long time parked, nor we often short distance driving, more accidental discharge. At this time the battery may not work, you can fully consider replacing it. But there are several basic situations analyzed above, then it is possible that the battery is discharged excessively and charging capacity is insufficient, this time the teacher can at the same time consider charging first.car battery manufacturers If after charging a few days after the same situation again, then not only can be comprehensive consideration of replacement.

2.Turn on the headlights when idling. If the engine speed fluctuates significantly, the battery may be low. Because the battery voltage must drop when the headlights are on, the generator begins to increase power to charge the battery. The more power the generator has, the higher the resistance and the more the engine idle fluctuates. Note that the idle fluctuation must be more severe here, not a lack of power as in fluctuation. Because even if the battery state is normal, turn on the headlights battery voltage will drop, but the drop is small, but in some cars will cause the idle speed to fluctuate slightly.

But this method can only determine a low battery, not battery life.battery coating But you can also come up with an approximation based on your daily performance. For example, if you use your car every day and drive it long enough, the battery should logically be fully charged.But when the headlights come on, the idle speed immediately fluctuates dramatically, which means the battery may not be working and can't store power.

3. Test with a battery tester. Battery tester can not simply measure the voltage to determine the battery capacity, because the battery is not loaded when the voltage is virtual, known as "no-load voltage", does not reflect the battery capacity.Battery tester is "bad", it will measure the high current discharge of the battery through the internal circuit, and then detect the voltage discharge of the battery, so as to truly reflect the actual situation of the battery.Nowadays, many 4s stores will give users free measurements during maintenance.However, it is not excluded that some people deceive consumers for the sake of performance, claiming that there are problems with normal batteries as batteries.So to be on the safe side, it is best to observe the procedure.

In fact, as long as it is used reasonably, car batteries should not be a problem for 5-6 years. If you can, buy a charger and charge the battery regularly, it will definitely benefit the battery life.
