How do I know this battery fits my Lenovo model?

Check the exact battery model number printed on your laptop's original battery by removing the back cover. The SUNNEAR L17C4PB0 corresponds to many OEM part numbers, so cross-referencing ensures a correct fit and connector alignment.

• Match the printed battery model (e.g., L17C4PB0, L17M4PB0) before purchase.
• Compare voltage (7.68V) and capacity (45Wh / 5928mAh) with your original battery.
• Confirm connector shape and screw placements via the open-back check.

How should I install and initialize the new battery?

Installation is straightforward if you take basic ESD precautions and follow the steps: power down the laptop, remove the back cover, disconnect the old battery, and secure the new unit in place. If the system doesn’t immediately recognize the new battery, a short sequence of charge/discharge cycles usually resolves initialization quirks.

• Turn off the laptop and remove any external power before opening the back cover.
• Ensure connector is fully seated; reinstall if the battery isn’t detected at first.
• Run the battery down to ~5% (not 0%), then charge fully and repeat 3–4 cycles to calibrate.
