• Locate the original battery inside the compartment. Before disconnecting, ground yourself and gently disconnect the battery connector from the motherboard, taking care not to pull on any cables or pins.
• Remove the existing battery by unscrewing or releasing any securing brackets or adhesive as designed by the chassis. Lift the old battery out slowly, avoiding contact with internal components or circuitry.
• Align the BTI Battery in the same orientation as the original, connect the battery connector securely to the motherboard, and reassemble the back cover or bottom panel. Reinsert screws and ensure the panel sits flush.
• Plug in the charger and power on the laptop to initialize calibration. If your device prompts a battery calibration, follow on-screen instructions or run a full discharge/charge cycle to optimize reporting accuracy.
• Once installed, monitor the first few charge cycles for any unusual heat or performance drift. If you notice anything unexpected, contact customer support for guidance. For first-time users, allow the battery to reach a full charge before heavy workloads to maximize longevity.
