Direct Replacement for IdeaPad 5-15 Series

This 15.12V 70Wh lithium-ion battery replaces the original L19L4PF1, L19M4PF1 and L19C4PF1 packs. It fits Lenovo IdeaPad 5-15ARE05, 5-15IIL05 and 5-15ITL05 models as well as Xiao Xin 15 2020 series laptops. The four-cell design delivers 4630mAh for extended runtime. Buyers needing a different voltage or a higher cell count should look elsewhere.

Verify Model and FRU Before Ordering

Check the bottom label of your laptop for the exact model number such as 81YQ, 81YK or 82FG and the FRU numbers 5B10W86940-950 or SB10W86946-960. The battery also matches industry codes 4ICP6/54/90 and 4ICP6/55/90. Confirming these identifiers prevents ordering a pack that will not sit flush or connect properly.

OEM-Grade Build with Safety Protection

The black lithium-ion pack is built to match original specifications and rated for 500+ charge cycles. It provides a stable 15.12V output with a tolerance of ±0.08V and includes overcharge and short-circuit protection. CE and RoHS compliance confirms the materials meet European safety and environmental standards. The internal connector aligns with the factory socket for a secure fit.
