The black cell arrives new and ready to install after reading the manual.

Thermals noise and power

Lithium-ion chemistry delivers stable voltage across the discharge cycle with no audible fan or moving parts. Normal operation adds negligible heat to the chassis and draws only the current the laptop requests. No external power supply is required beyond the standard ThinkPad adapter already used with the system.

Capacity decides fit

The 24 Wh 2100 mAh rating determines whether this pack meets your runtime needs. Verify the original battery model number on the back case before purchase because this unit will not fit T460S T470S or T480S models. If your machine requires a higher watt-hour rating this battery is not the correct choice.

Questions about this item

How do I install the 01AV423 battery in my ThinkPad T480 and what step is often missed?

Remove the bottom case, disconnect the old battery connector, fit the new 11.4V pack, and reconnect; the step often missed is checking the original battery part number against the 01AV423 list before ordering.

What maintenance will the 24Wh lithium-ion pack need over time?

No routine maintenance is required; the battery will eventually hold less charge and should be replaced when runtime no longer meets your needs.

What is the first limit I will hit when using the 2100mAh battery continuously?

The 24Wh capacity determines how long the laptop runs before the pack must be recharged.
