Thermals noise and power draw

Lithium-ion chemistry produces negligible heat and no audible noise during normal office workloads. The 11.4V nominal voltage matches the original specification so the system power management operates without modification. Current draw scales with the laptop's instantaneous load rather than the battery itself. No active cooling is required for the pack.

Sustained load behaviour

Under continuous heavy use the cell voltage will decline steadily until the firmware initiates a controlled shutdown. The 24Wh capacity limits total run time to the quoted 3-6 hour window depending on screen brightness and CPU demand. The pack does not support hot-swap operation so the laptop must be powered down for installation. Users needing longer unplugged sessions should consider a higher-capacity alternative.

Questions about this item

How do I install the 45N1112 battery and which step do people miss?

Power off the laptop, remove the bottom case screws with the included screwdrivers, disconnect the old battery cable, connect the new 11.4V 24Wh pack, then reattach the case screws before turning the system on.

What maintenance or replacement will the 4-cell 2060mAh battery need later?

The lithium-ion pack will lose capacity over repeated charge cycles; plan to replace it once runtime falls well short of the 3-6 hour range.

What limit appears first during sustained use of the 11.4V 24Wh battery?

The 24 watt-hour capacity sets the runtime ceiling, so the battery will reach empty after the stated 3-6 hours of continuous load.
