Replacement Battery for IdeaPad Slim 3

This new lithium-ion pack is built to match the original 11.31 V 4156 mAh specification for IdeaPad Slim 3 models in 14‑, 15‑ and 16‑inch sizes. It suits owners whose factory cell no longer holds a useful charge and who want a direct drop‑in replacement.

Three‑cell design for steady daily use

The three‑cell layout delivers consistent voltage across a full workday rather than a brief peak, so the laptop runs at its normal profile without sudden throttling. Capacity is rated to sustain typical office and streaming loads from morning to evening.

Verify your exact model and part number

Before ordering, confirm that your machine appears in the supported list — such as 14AMN8, 15IAH8 83ER, 16IRU9 83E7 or the V14/V15 G4 variants — and that the OEM part number on your old battery matches one of the listed references. The pack will not fit laptops outside this series.

Questions about this item

Does the 3-cell 11.31 V lithium-ion pack run hotter than the original after a full day of use?

It matches the factory 11.31 V 4156 mAh specification, so thermal behaviour stays within the laptop's designed cooling envelope.

My Ideapad Slim 3 14AMN8 currently uses OEM part 5B11K09317 — is that the only item I need to swap?

Yes, the battery replaces OEM 5B11K09317 directly; no extra cables, brackets or tools are required.

Will this 11.31 V pack work in my older Ideapad 5 Light 14ABR8 that originally shipped with a 5B11K09309 battery?

The 5B11K09309 is listed among the compatible OEM numbers, so the pack fits and communicates correctly with that model.
