Before purchasing a new laptop battery, it is important to follow the steps below to ensure you get a compatible and safe option:

1. Accurate Specification Matching

• Part Number: Make sure the code printed on the old battery matches (such as C31N2105).
• Voltage: The number must match exactly (such as 11.61V). A voltage difference may prevent the device from working or damage the motherboard.
• Capacity/Watt-hour: It is preferable for the capacity to match the original battery (such as 70Wh). You can choose a higher capacity if it is available in the same size.
