6-cell 5200 mAh replacement battery

This 10.8 V lithium-ion pack uses six A-grade cells rated for up to 500 recharge cycles. It replaces Lenovo part numbers including 45N1762, 45N1763 and 4X50G53717. The unit fits ThinkPad Edge E550, E555, E560 and E565 series laptops. Built-in safeguards cover short-circuit, over-voltage, over-current, over-temperature and deep-discharge protection.

Sustained run-time behaviour

The 5200 mAh capacity is designed to deliver consistent output across the full discharge curve rather than only in brief bursts. Integrated protection circuits maintain stable voltage while preventing cell stress during extended sessions. CE, FCC and RoHS certifications confirm the pack meets baseline safety standards for continuous operation.

Pre-installation checks

Verify your laptop model matches the E550, E555, E560 or E565 series before ordering. Confirm the original battery carries one of the listed replacement part numbers such as 45N15E9 or 45N8961. Ensure the machine accepts a 10.8 V, six-cell form factor and that the BIOS is current enough to recognise a new pack.

Questions about this item

Does the 10.8 V 5200 mAh pack generate noticeable heat or fan noise during all-day use?

The lithium-polymer cells run cool under normal loads; no fan is present and the built-in over-temperature protection keeps the pack within safe limits during extended sessions.

Which original Lenovo part numbers must match for this 6-cell replacement to fit my ThinkPad?

It replaces part numbers 45N1762, 45N1763, 45N1758, 45N15E9, 4X50G53717, 45N8961 and 3INR19/65-2, covering E550, E555, E560 and E565 models.

Will the battery charge correctly with the 45 W, 65 W or 90 W AC adapter I already use on my older ThinkPad?

Yes — the pack accepts the standard ThinkPad barrel-tip chargers rated 45 W, 65 W or 90 W, so your existing adapter works without change.
