MULS BTY-M57 65Wh Laptop Battery Compatible with MSI GP66 GP76 Leopard Models

About MULS: Professional Battery and Adapter Experience 1. We strictly test each battery before shipment to ensure full capacity and safety without harming the computer. 2. We recommend the first charge to be no less than 5 hours. 3. If a new battery cannot be charged, it is usually not a problem with the battery. The computer charges the battery for the first time, and due to voltage and current instability, it may stop charging when the battery is half full. Simply remove the battery and recharge it again. This is normal for a new battery. 4. When the battery is discharging, it must be shut down or recharged when it reaches 3%. Discharging to 0% will damage the battery and reduce its lifespan. 5. Avoid dropping, heating, or short-circuiting the battery. Do not use it in high or low temperature environments.
