The battery of the recording pen is stored for a long time without being used. As there is a protection circuit inside the battery, it will continue to consume power and the battery also has a certain amount of battery life. Dump. When the battery voltage is lower than a certain value, it will cause indestructible damage.
Generally speaking, most digital recorders use built-in lithium batteries. Some older recorders use AAA AA batteries, and some low-end products use button batteries.
The advantage of using ordinary batteries is that they can be replaced, but the volume is relatively larger; Button battery recorders are usually used for promotional gifts etc. for one-time or short-term recording. Consumers can choose which power mode recorderion according to their own needs.
The digital recording pen, a type of digital recorder, is shaped like a pen and is easy to carry. It also has multiple functions, such as laser pointer function, MP3 playback, etc. Compared to traditional recorders, digital recorders record audio via digital storage.
Why don't recorders use lithium batteries?
Remove the battery and take a look. Usually it is a lithium battery, you can buy a universal charger for about 15 yuan. If the battery is not removable, look at the charging interface of the recorder, and then purchase an adapter according to the model, which costs about tens of dollars. Most cell phones come with lithium battery chargers. If they can be plugged into a recorder, they can be charged as long as the recorder diuses a lithium battery.
The reason why the recording pen does not use lithium batteries can be mainly considered from three aspects: safety, service life and environmental protection:
D From a safety point of view, the recording pen, as a portable recording device, frequent use and easy operation. Although lithium-ion batteries have advantages in energy density and cycle life, their safety is relatively low and they are prone to combustion or even explosion under abnormal conditions such as overcharge, discharge. excessive and a short circuit. As a daily necessity, the safety of the recording pen is undoubtedly very important. In comparison, other types of batteries, such as nickel-metal hydride and nickel-cadmium batteries, offer higher safety.From the point of view of lifespane, voice recorders generally need to be used for a long time, and battery life is crucial to user experience. After long-term use of lithium-ion batteries, their service life will decrease significantly, affecting the performance of the equipment. However, the performance of nickel-metal hydride batteries, nickel-cadmium batteries and other types of batteries degrades relatively slowly after long-term use, which can better meet the needs of long-term use of recording pens.
From the perspective of environmental protection, the production process of lithium-ion batteries will produce a certain amount of environmental pollution, especially when processing waste batteries, the chemical substances that they contain cause potential damage to the environment. Although lithium batteries can be recycled, the taRecycling ow is relatively low. Nickel metal hydride and nickel cadmium batteries have relatively little impact on the environment during the production process and can also be recycled after disposal. Therefore, from an environmental point of view, other types of batteries are more suitable for voice recorders.
In summary, the reason why recording pens do not use lithium batteries is mainly due to safety, service life and environmental protection considerations. .consider. Although lithium batteries have advantages in energy density and lifespan, their low safety, short lifespan, and potential environmental damage make other types of batteries more suitable for voice recorders.
