Practical Limits of Lithium-Ion Chemistry

Capacity diminishes gradually with each charge cycle, so runtime will shorten over months of daily use. The 52.5W rating reflects the design specification when the pack leaves the factory. High temperatures accelerate ageing, while deep discharges can reduce overall service life.

Compatibility Checks Before Ordering

Verify the exact model number printed on the bottom case or in the BIOS matches one of the five listed part numbers. Confirm the original battery voltage is 11.55V and that the physical pack uses three cells. Ensure the laptop chassis accepts a standard 3-cell form factor without custom brackets or cables.
