how to install BTI NNF1C-BTI 7.6V 46WHR LI-ION BATTERY

• Power down the device completely and disconnect it from any charging source. Ensure the laptop is cool to the touch before beginning the replacement process.
• Prepare your workspace on a clean, non-conductive surface and gather the necessary tools (typically a small Phillips-head screwdriver and a plastic pry tool). Disconnect any peripherals to avoid interference during the replacement.
• Remove the back cover by locating and removing the screws that secure the base chassis. Keep screws in a labeled container so you don’t mix them up during reassembly.
• Carefully disconnect the old battery’s connector from the motherboard. Use a gentle rocking motion with a plastic pry tool to separate the connector without damaging the socket or surrounding circuitry.
• Remove the old battery module from its bay and inspect the cavity for any residue or debris. Position the BTI NNF1C-BTI 7.6V 46Wh Li-ion battery in the same orientation, aligning screw holes and connectors with the chassis.
• Reconnect the battery connector firmly to the motherboard, reseal the back cover with the original screws, and power on the device. If prompted, perform any battery health calibration or setup steps recommended by the operating system to optimize new-cell performance. Allow the device to run for a short period to ensure normal operation and confirm the battery status shows as healthy in the system settings.
