46 Wh replacement battery for ThinkPad L13 Yoga

This lithium-ion pack delivers 46 Wh at 15.36 V and is built for Lenovo ThinkPad L13 Yoga 1st Gen and 2nd Gen systems, including the 20R5 and 20R6 series. It replaces original part numbers such as L18C4P90, L18M4P90, L18D4P90, 02DL030 and 02DL031.

Internal lithium-ion cell

The battery uses a standard lithium-ion chemistry and plugs straight onto the laptop's internal power rail, so no external cables or adapters are required. Installation follows the usual ThinkPad bottom-cover removal procedure and the black casing matches the original aesthetic.

Single battery unit in the package

Only the battery itself is supplied; no tools, screws or software discs are included. The 12-month warranty covers defects in materials and workmanship. Buyers needing a higher-capacity pack or a different voltage variant should verify their original part number before ordering.
