Installation & Care Tips
Check part number / shape: Ensure it matches BR04XL (not BT04XL, etc.)
Initial calibration: Charge to 100%, discharge to ~5%, then fully recharge (repeat once) to help the battery gauge accurately report capacity
Maintenance: Avoid keeping the battery at full charge constantly; charge to 80%, discharge occasionally to around 20–30%.
Avoid fake batteries: Non-genuine brands may seem affordable but often offer lower capacity, shorter lifespan, and may lack firmware compatibility—OEM units avoid “battery not supported” warnings.
