Common models LR series button battery: This series of battery voltage of 5V, widely used in a variety of small electronic products, such as watches, hearing AIDS, small toys and so on. There are a variety of different battery sizes under the LR model, such as the LR4LR1. AG series button battery: mainly used in various electronic labels and anti-theft devices and other occasions. The voltage of the AG battery is generally between 5V and 3V, and the specific size is selected according to demand.
CR2032: This is the most common type of button battery, with a diameter of 20mm and a height of 2mm. CR2032 is widely used in computer motherboards, car keys, electronic scales, remote controls and other fields. CR2025: The button battery of this model has a diameter of 20mm and a height of 5mm. Compared to CR2032, its thickness is thinner, so it is suitable for some battery thickness specificRequired equipment, such as certain thin remote controls.
1, in the battery direction, Apple AirPods1 and 2 generation are using steel shell pin battery, but in AirPods Pro replaced with steel shell buckle battery, this change also makes the brand manufacturers on the market quickly follow up. I love audio network follows the development of the TWS headset market, and has made detailed disassembly reports on nearly 300 products in a few yearsAt present, many brands have also used steel shell buckle batteries as their own TWS headset power supply source.
2. Disassemble the earphone, open the earphone along the closing line, and the structure of the loudspeaker unit inside the front cavity and the battery unit inside the rear cavity is clearly visible. A close-up of the front diaphragm of the speaker unit shows the sound quality details, and the back edge is equipped with tuning holes, protected by tuning cotton. The speaker size is about 13mm. The bottom structure of the rear chamber shows the connection between the battery and the speaker wire, and the steel shell buckle battery is used inside the headset. The battery model is LIR1040 with a nominal voltage of 6V.
3After disassembly, the audio network found that the headset is equipped with a 12mm moving-coil unit and is equipped with three MEMS microphones to provide pickup function. The battery is designed with a steel shell buckle, equipped with the CM1126B-GAC battery protection IC, providing comprehensive protection, suitable for single lithium-ion/lithium polymer batteries, with shipping mode, suitable for Marine transportation and long-term storage.
4. The positive electrode of the steel shell buckle battery used inside the headset is wrapped with insulation tape for protection. Close-up of the negative electrode of the steel shell buckle battery. Steel shell button battery from LIDEA Electric Electronics, Model: LIR1040, electricVoltage: 5V. Headphone speaker front close-up with metal cover. A close-up of the back of the speaker features a tuning hole protected by a fine air filter to improve acoustic performance. Speaker size compared to a dollar coin.
5, the battery is wrapped with high temperature insulation tape, and the bottom is set up with sponge cushion buffer protection. The headset part includes motherboard, Bluetooth antenna, touch detection patch, call microphone pickup acoustic structure, coaxial double moving coil unit, MEMS microphone, Bluetooth audio SoC, voltage regulator IC, touch chip, charging IC, etc. The battery uses steel shell buckle design, built-in lithium protection IThe button battery in the battery will die soon, how to repair it?
1, reduce the screen brightness, reduce the use of built-in optical drive and speaker. Turn off wireless cards and Bluetooth devices that are not in use. Set your computer's power mode to "Energy Saving" or "Balance" mode. Battery as a consumable, there is a certain loss is a normal phenomenon. As the use of time increases, the battery life may gradually decrease.
2, adjust the power mode to "energy saving", "balance". The battery is a consumable product, there is a certain loss is normal, after a period of use, the battery life will be shorter and shorter. You mayTo try to correct the battery level by fully charging and discharging the battery, the following is how to do it: unplug the external power supply, turn on the battery only and enter the BIOS. Wait for the battery to run out until it automatically shuts down.
3, taking the computer motherboard as an example, its button battery is out of power, it is recommended to replace the new battery. In general, there are two common types of button battery models, charged and non-charged. Rechargeable batteries include 6V rechargeable lithium-ion button batteries, 3V rechargeable lithium-ion button batteries, and non-rechargeable batteries include 3V lithium-manganese button batteries and 5V alkaline zinc-manganese button batteries. Note that the current must be less than 10 when chargingMA, charge time is usually two hours, one hour off.
Button battery model comparison table CR series: for example, CR2032, where CR represents lithium manganese dioxide battery, 20 indicates the diameter of 20mm, 32 indicates the thickness of 2mm. The voltage is usually 3V. AG series: such as AG13 or LR44, which are often called alkaline zinc-manganese batteries in China. In the IEC standard, L stands for alkaline and R for circular.
Button battery model table is as follows: relatively commonSee button batteries are used for toys and gifts on the AGAGAG13 battery, computer host board battery model CR2032, used in the electronic dictionary CR2025, for the electronic watch above CR2016 or SR4SR626 and so on.
The common button battery model comparison table includes a variety of models, each model corresponds to a different voltage, size and purpose. The following are some common button battery models of the CR series: CR series batteries with lithium metal as a negative electrode, manganese dioxide as a positive electrode, with a nominal voltage of 3V. In its model naming rules, the four digits after CRThe first two digits represent the diameter, the last two represent the thickness.
- For example, 8x6mm corresponds to Swiss model 337=SR416SW and Japanese model 335=SR512SW. The button battery installation method - usually follows the principle that the positive pole with the letter faces up - puts the positive pole with the letter into the battery bin when installing, and presses to fix the button battery price - The price varies according to the type, specifications, brand and other factors, ranging from a few cents to 5 yuan.
