You can search for tutorials from Google. It is best to check the tutorial before DIY, so as to avoid unnecessary losses during the disassembly process. Before disassembling your laptop, put the old battery charge below 25%. If a fully charged lithium battery is accidentally punctured, it will have serious consequences. Protect your screen and touchpad. Keep every screw you removed. Do not reverse the positive and negative. Make sure the power connector is fully seated, the tabs needed to touch the metal. New battery: Discharge the new battery to 10% (not 0%), then charge it to 100%. Cycle 3-5 times to activate its maximum capacity before use. Overuse: Do not always run out of a battery to 0%, this would make it damaged or usage life shortened. Charging sequence: When charging, first install the battery, then plug in the power; when fully charged, first cut off the power, then pull the power plug. Adapter: Use the adapter from a regular manufacturer. If the original adapter cannot be applied due to malfunction or damage, please replace it. Why the laptop does not recognize the battery or the laptop does not display the battery? Could be caused by battery loose. Please re-install the battery and make sure that the battery cable and the motherboard interface are tightly inserted. May be due to conductive material damaged which the laptop motherboard and battery anode and cathode contact position, you can try to confirm it with your original battery. Check whether the battery drive is in normal condition, if not, download the corresponding driver software to update. ANTIEE was born from a simple belief -------your laptop deserves a battery that works as hard as you do. For years, we experienced the same frustrations as every user — Batteries aging too fast Sudden shutdowns during important work Replacement batteries that failed to deliver reliability So we built ANTIEE to change that. Every ANTIEE laptop battery is engineered around three promises: • Reliable Power — consistent performance for work, study, travel, and creation. • Proven Safety — multi-layer protection against overcharge, overheat, and short-circuit. • Extended Lifespan — high-grade cells and optimized BMS calibration for longer cycle life.

The “Maximize My Battery Health” setting limits the maximum state-of-charge on the notebook battery to 80%, which has been proven to optimize battery health and helps mitigate battery swelling due to high state-of-charge. If not required, Change this setting. If your battery is still defective, we will be responsible for your situation. 1.Lithium batteries have no memory effect. It does not need to be fully charged and discharged deliberately, and it is generally enough for normal use. 2.The only thing to note is that lithium batteries have a "self-discharge" feature. During the storage period, the power will still decrease slowly. 3.Long-term storage with the battery discharged to 0% may damage the battery and render it unusable. 4.When not using the laptop for a long time, charge the battery to 50%, turn off and remove the transformer, recharge the battery to 50% every three months. ## Features - 【Specification】Voltage: 11.52V.
