Absolutely. The part number PABAS245 is on our list of verified compatible references for this battery. You can buy it with the assurance that it will replace your original battery without any compatibility issues, offering the same voltage specifications and reliable performance.

Do I need to do anything special when installing the battery for the first time?

Yes, to optimize battery performance and lifespan, we recommend an initial calibration cycle. Once installed, charge it to 100% without interruptions. Then, use the laptop until the battery is completely discharged or the system warns of a low level. Repeat this full charge-discharge process 2 or 3 times. This helps the operating system recognize the battery's actual capacity.
