Questions about this item

How much heat does the 11.4 V 2100 mAh lithium-polymer pack produce during a full workday?

The 11.4 V lithium-polymer cells run cool under typical office loads; normal warmth is expected but the pack stays within safe thermal limits thanks to built-in over-heating protection.

What must my ThinkPad already have for this 24 Wh replacement to fit and charge?

Your T470, T480, T570, T580, P51s, P52s, A475, A485 or TP25 needs the standard internal battery bay and the original Lenovo charging circuit — no extra cables or adapters are required.

Will the 01AV452 / 01AV423 pack work alongside the older 01AV422 or SB10K97582 battery I kept as a spare?

Yes — both part numbers are listed as compatible, so you can swap between this 24 Wh pack and the older spare without any BIOS or hardware changes.
