Fits the existing battery bay without modification

The pack matches the mechanical footprint and connector layout of the listed OEM part numbers so it slots straight into the laptop chassis. No adapter cables or firmware updates are required and the original AC charger continues to handle recharging duties.

Steady output through a full workday

An integrated smart control chip regulates charge current to reduce heat buildup during extended use and protects against short circuit, overheat and overload conditions. The 48 Wh rating supports consistent discharge across long sessions rather than only brief peaks.
