My laptop still shuts off early after replacement.

Run two full charge/discharge calibrations, update BIOS and power drivers, and verify the AC adapter wattage is correct. If the issue persists, review thermal health or system board power rails.

How can I extend new battery lifespan?

Keep temps cool; avoid blocking vents.
Avoid 0% and 100% extremes daily—40–80% is gentler for storage.
Update BIOS/firmware for better charge control.
