Questions about this item

Does the 61Wh 15.44V battery run hot or draw extra power during all-day use?

The lithium-ion pack is rated at 61Wh and 15.44V, matching the original specification for the ThinkBook 14p G2 ACH, so heat and power draw stay within the laptop's normal design limits.

Must I already own a ThinkBook 14p G2 ACH for this battery to work?

Yes — the pack is built for the ThinkBook 14p G2 ACH and replaces part numbers L20B4PD2, L20C4PD2, L20D4PD2, SB11C04258, SB11C04259 and 41CP5/38/123.

Will the 15.44V 61Wh pack fit if my current battery shows part number 41CP5/38/123?

The 41CP5/38/123 part number is listed as directly compatible, so the battery will install and operate correctly in that machine.
