button cell

The BR2354 is a 420mAh 3V coin-type Lithium Battery with a voltage of 3V. It has terminals that are in contact with the pressure. It is well suited for application in a wide range of devices where miniaturization is becoming more popular. Because manganese dioxide, which is chemically very stable, is employed as active material in the plus terminal, it retains 90% of its capacity even after 10 years of storage if preservation requirements are met. It uses organic electrolytes with the least amount of creep, which is far superior in terms of leakage resistance when exposed to environmental changes.

ML2020 Rechargeable Lithium Coin Cell employs specially treated manganese dioxide for the positive material and a lithium-aluminum compound for the negative material. A specially formulated organic electrolyte is also used, yielding excellent discharge characteristics with low self-discharge.

ML1225 Rechargeable Lithium Coin Cell is a new type of rechargeable Li-ion button cell, with a positive material of LixMnO2 instead of LiCoO2, and a negative material of Li-AL alloy instead of C. With a 3.0V voltage, stable cycle performance and perfect safety performance, the ML button cell is becoming the most popular type of Li-ion battery.

Lithium-aluminum button battery High working voltage: Rated voltage of the battery is 3.0V Can be recycled charging: low voltage lithium manganese acid is positive, lithium aluminum alloy is negative secondary lithium ion battery Operating temperature range is wide: can work in the range of -20℃ ~ 70℃ Low self-discharge rate: annual self-discharge rate is not more than 2%

High-temperature resistance Excellent discharge stability High voltage, high energy density Superior strorage characteristics

Low-temperature resistance Excellent discharge stability High voltage, high energy density Superior strorage characteristics
