Questions about this item

How long will the 57Wh 4950mAh capacity last under continuous load before needing a recharge?

Runtime depends on the ThinkBook 14-IML or 15-IIL power draw; the 57Wh 4950mAh pack typically delivers several hours of mixed use before reaching 5 percent.

Does the 11.52V lithium-polymer cell run hot or make noise during all-day operation?

The sealed 11.52V Li-polymer unit has no moving parts, so it is silent and only warms slightly under normal charging and discharge cycles.

Which original battery part number must already be in my ThinkBook for this L19M3PF2 to fit?

It replaces L19C3PF9, L19C3PF1, L19M3PF9, L19D3PF1, L19M3PF1, L19L3PF1, L19D3PF2 or L19L3PF8 — verify the label before ordering.
