【Compatible Product Models】: The battery undergoes compatibility testing after production. Please check whether your device model matches the battery model before purchase to ensure the accuracy of your purchase. 【High Capacity Battery Life】: The high capacity provided by the battery is from the newly upgraded 0-cycle product. It offers long working time and eliminates the need for frequent charging. 【Safety Features】: The battery is equipped with an integrated insulation membrane and an intelligent integrated circuit chip. It features multiple safety mechanisms such as overcharge protection, overdischarge protection, short-circuit protection, and a thermal management system. In high-temperature environments, it automatically reduces frequency and shuts down power supply, with a working temperature range of -20°C to 60°C. 【Cycle Life and Durability】: Utilizing A-grade lithium-ion/polymer batteries, these offer high energy density and long cycle life. They can withstand multiple charging and discharging cycles without significantly reducing capacity. The batteries can endure 600 cycle periods and maintain 70% capacity even after completing the charging cycle. 【Fast Charging & Efficient】: Utilizing intelligent fast charging technology, it automatically adjusts the optimal current, increasing the charging speed by 30%. Once the battery is fully charged, it automatically cuts off the power supply to prevent battery expansion. For the best charging results, please use the original charger. Before purchasing, please double-check the battery model to avoid buying the wrong one. Battery Usage Instructions: 1. After replacing the battery, please discharge the battery to about 20% to 30% of its capacity, then charge it with the original charger for 6-8 hours. Repeat this process 3-5 times to activate the battery properties and achieve the best performance. 2. Avoid deep discharge: When the battery's charge level is low, immediately charge the device. Over-discharging (with a voltage lower than 2.5V) will permanently damage the battery. Do not always set the battery charge level to 0% as this will damage the battery or shorten its lifespan. 3. Do not disassemble or press: Do not disassemble or replace the battery structure. Lithium batteries contain flammable explosive substances. Non-professional operation may cause an explosion or fire. 4. Long-term storage: Keep the battery at a charge level of 40% to 60% (commonly known as "semi-charged storage"). Avoid keeping it fully charged or idle for a long time. Charge the battery once every 3 months. 5. Avoid overcharging: Turn off the power immediately after fully charging. If using the device for a long time with the power on, the battery may expand. 6. When using a genuine charger: A genuine charger may damage the battery due to inconsistent voltage/current, posing safety risks. 7. Visual inspection: If you notice any bulging, deformation, leakage, oxidized interface, etc. on the battery, stop using it immediately.
