The electrical appliances at home are burned out by the battery, whose fault is this? Everyone must think that this can be whose fault, the battery quality must be not up to par, find the battery manufacturer!
But in fact, it is very likely that we really misunderstand the battery.
In September 2023, a netizen in Jiangsu said on the Internet that he had used a mouse for almost ten years, and it exploded and went on strike after installing a big-name battery, and he was very angry and disgusted between his words.
There are also people who bought a set of remote-controlled cars for their nephews in the supermarket, but it turned off in less than a few days, and after installing a certain big-name battery, the remote control did not even light up, and it could not be connected to the remote-controlled car.
There are even some consumer feedback that smart locks or projectors cannot use a certain big brand battery.
Is it because the quality of this big brand battery is not up to par? That's really not, in fact, the instruction manuals of many electrical appliances indicate that the appliance is not suitable for a certain big brand battery.
Why is there so much attention to such a small thing as a battery? Is it really a problem with the battery? But people are obviously big-brand batteries, and they should not make such a basic mistake in terms of technology or product quality.
Here we first want to popularize some knowledge about batteries.
The first is alkaline batteries. It is one of the most common household batteries, and its internal electrolyte is an alkaline substance, such as potassium hydroxide.
Alkaline batteries are widely used in various portable electronic devices, such as remote controls, flashlights, electronic clocks, etc. They are lightweight, inexpensive, and easy to use and handle, but typically only provide relatively small currents and are not suitable for use in high-load applications.
The second type is lithium batteries. It is a commonly used secondary battery that relies on lithium ions to move between the positive and negative electrodes to achieve multiple charge and discharge.
Lithium batteries are widely used in new energy vehicles, electronic products, energy storage equipment, power tools and other fields due to their high working voltage, high energy density and long cycle life.
The third type is the nickel-metal hydride battery, which is a battery with good performance.
NiMH batteries can provide similar performance to lithium batteries, are more durable in terms of battery charge and discharge cycles, and are also more environmentally friendly. As a result, it is suitable for use in cameras, laptops, and other high-power electronic devices.
The fourth is lead-acid batteries, which are mainly used for starting power for vehicles, motorcycles and other vehicles, as well as backup power and energy storage equipment.
Obviously, different kinds of batteries have different ranges of use. When choosing a battery, we need to choose the right battery type according to the specific application scenarios and needs. But the problem comes, obviously a big brand battery is an alkaline battery, which is suitable for daily household appliances.
Moreover, the experimental results show that the nominal voltage of the common No. 5 battery is 1.5 volts, and the maximum open-circuit voltage required by the national standard is 1.68 volts, while the maximum open-circuit voltage of a big-brand battery is only 1.632 volts, which is fully in line with the standard, so there is no possibility of excessive voltage causing damage to components.
So why do so many electrical toys claim that a certain big brand battery is not suitable for their products? This has to be analyzed from the product itself and the principle of battery use.
The first is the quality control of electronic components, that is, the quality of those products themselves. In order to control costs, some smart door locks or toy manufacturers do not use reasonable and regular voltage regulator components on the premise of keeping the battery discharge in the national standard as a whole, so the circuit will burn out at a certain moment because there is no voltage regulation control.
The second is the design of the product itself. There are some low-cost toys or electrical appliances, their own battery compartment is not standard, the copper sheet on both sides is not the same, when the battery is stuck by the anti-installation device, a certain pole of the battery may not be able to contact the copper sheet at one end, so the view that "the alkaline battery current is too large, and the overcurrent protection of the chip will make the product unable to be started" is also wrong.
The third is that some products that have not passed the 3C compulsory certification will cut corners in the production itself, reduce the resistance components, lack of overcurrent protection chips, or use low-standard thin coils, which will lead to a larger current than normal and no line protection at the same time, and the product will have a chance of damage.
Another reason is that the circuit design of some products themselves and the voltage and current of the battery do not match the parameters of a certain big-name battery, so there is an incompatibility.
But at the end of the day, the damage to these appliances really has nothing to do with the quality of a big-name battery. The internal resistance of alkaline batteries is low, and the output voltage of the battery will drop to less than 1.6 volts when in use, which belongs to the normal voltage range of electrical appliances such as toys, clocks, and smart locks.
Moreover, in the process of discharging, the voltage and current of the alkaline zinc-manganese battery drop slowly, the working voltage platform is stable, and the use time is longer, so the battery voltage is too high to cause damage to toys, clocks and other electrical appliances or shorten the service time of electrical appliances.
The working current of the battery is determined by the load of the electrical appliance, whether the battery will burn out the electrical appliance depends more on whether the battery and the electrical appliance match, and the full power of a big brand battery only means that the service life of the electrical appliance is longer than that of ordinary electrical appliances.
Therefore, for those electrical toys that indicate that a certain brand battery cannot be used, we should think more about its own design rationality and manufacturing safety, and pay attention to whether the parameters between the battery and the electrical appliance match.
However, in the face of various means in the market, consumers do not necessarily understand the goods, and there will be damage to electrical appliances due to improper use of batteries.
This is often a multifaceted issue.
When using electrical appliances, consumers should carefully read the product's instructions and battery requirements to ensure that the battery is used in the correct way. If the consumer does not follow the product instructions and uses the battery incorrectly, resulting in damage to the electrical appliance, then the consumer also needs to bear some responsibility.
However, when manufacturing and selling electrical appliances, businesses should ensure that the product is properly designed, that the instructions for use are clear and clear, and that consumers are clearly informed about what type of battery they should use.
If the merchant has a product design flaw, unclear instructions for use, or does not clearly inform the consumer of the battery requirements, resulting in the consumer using the wrong battery and causing damage to the appliance, the merchant will be held liable in this situation.
However, according to Article 40 of the Law of the People's Republic of China on the Protection of Consumer Rights and Interests, if a consumer's legitimate rights and interests are harmed when purchasing or using goods, he or she may claim compensation from the seller. If it is the responsibility of the producer or the responsibility of other sellers who provide goods to the seller, the seller shall have the right to recover from the producer or other seller after compensation.
This means that if the damage to an appliance is due to a problem with the battery, and the battery was provided by the merchant, then the consumer has the right to claim compensation from the merchant.
