Frequently asked questions
How can I tell if this PA3728U-1BRS battery is compatible with my laptop?
The safest way is to remove the current battery from your laptop and check the part number printed on the label. If it matches PA3728U-1BRS, this battery is the correct one. You can also compare the voltage (V) and physical shape with the product images to ensure a perfect fit.
Is it necessary to calibrate the battery the first time I use it?
Yes, it is recommended. To calibrate it, charge the battery to 100% with the laptop turned off. Then, turn it on and use it on battery power until it is completely depleted and the device shuts down. Finally, recharge it to 100% without interruptions. This process helps the system recognize the new battery's actual capacity.
What warranty does the battery have and what should I do if it doesn't work or fit properly?
The battery has a 3-year warranty for private individuals and 1 year for professionals. If upon receipt it does not fit or does not work correctly, you have 14 days to return it.
