Installation Notes, Safety, And Calibration
Preparation Starts With Draining The Old Battery Below Twenty Percent, Powering Off, And Isolating The Logic Board Before Any Adhesive Work. Removal Is Easiest With Controlled Heat And Adhes Remover Applied Under Each Cell Segment, Taking Care To Avoid Twisting Or Puncturing The Pouches. Seating The New Pack On Clean Aluminum With Fresh Adhesive Ensures Even Contact And Prevents Lift Over Time. A Final Visual Check For Pinch Points Along The Flex And Under The Speaker Cavities Helps Avoid Intermittent Disconnects.
Post‑Install Calibration Helps The Controller Sync To The Host. A Good Routine Is To Charge To One Hundred Percent, Rest On Charger For Two Hours, Discharge To Around Five To Ten Percent In Normal Use, Then Recharge To Full Without Interruption. An Smc Reset Can Be Performed If Percentage Reporting Seems Inaccurate After The First Cycle. Operating Temperatures Between 10–35 °c And Storage Around 40–60 Percent Charge Promote Longer Service Life, While Avoiding Deep Storage Discharge Prevents Permanent Capacity Loss.
