✓ This is a secondary ultra-extended slice battery, not the computer’s smaller primary battery.
✓ It does not replace CM03XL-style primary batteries. The primary battery can remain installed while the CO06XL is attached.
✓ Verify that the underside of the computer has the matching accessory-battery connector, alignment points, and locking locations.
✓ Do not order solely by notebook family name. Some configurations may lack the required underside connector.
✓ The battery adds thickness and weight to the computer and may affect compatibility with fitted sleeves, stands, docks, or carrying cases.
✓ Align the connector and mounting points before engaging the latches. Never force the battery into position.
✓ The original retail battery kit may have included a power-connector dongle. This listing includes the battery only unless an additional cable or dongle is specifically shown or stated.
✓ Actual operating time depends on battery condition, system configuration, screen brightness, workload, wireless usage, and the condition of the primary battery.
✓ A system firmware update may be helpful if the battery is installed but is not immediately recognized.
✓ Recycle depleted lithium batteries through an approved battery-recycling facility.
