Reliable functionality and full compatibility with the wireless headphones. Precisely manufactured to fit your device perfectly. CE and RoHS certified – complies with all operational safety guidelines. No memory effect. High-quality Li-Ion cells for optimal device performance. Lithium-ion batteries have high energy density and are among the strongest batteries. They have a low self-discharge rate compared to NiMH batteries and are not subject to memory effect. They do not require regular discharging, thus requiring little maintenance. With proper storage, these rechargeable batteries are long-lasting, durable, and have many possible charging cycles. Li-ion batteries are used in various high-energy portable devices such as smartphones, notebook computers, cameras, and electric power tools. These batteries can also be used in radio-controlled models and telecommunications applications. Note: For lithium-ion replacement batteries with significantly higher capacity (1000 mAh and above), the replacement size may vary slightly, making it slightly heavier or thicker. As a result, the replacement battery may protrude slightly.
