76Wh replacement battery for Lenovo IdeaPad 5

This 76Wh lithium-ion unit replaces the original L21C4PH2 series battery in Lenovo IdeaPad 5 15IAL7 and 15ABA7 models as well as the Xiaoxin Air 15 IAL7 2022. It is built for owners who need a direct swap to restore full mobility. The black pack carries part numbers SB11F48153 and 5B11F48161 among others.

Capacity and daily headroom

Rated at 76Wh and 4947mAh the cell delivers a full day of typical office work or web browsing on a single charge. Heavy workloads such as video editing or sustained gaming will drain it faster and may require a mid-day top-up. The 15.36V output matches the factory specification so the system reports capacity correctly.

Thermals and power behaviour

Lithium-ion chemistry runs cool during normal charging and discharging cycles. No audible noise is produced because the pack has no moving parts. Power draw follows the laptop's own management profile so the battery does not impose extra load on the charger.

Questions about this item

Will the 15.36V 76Wh battery work in my IdeaPad 5 15IAL7 that currently uses a 57Wh pack?

Yes, the 15.36V 76Wh cell replaces the original L21C4PH2 part and fits the 82SF chassis without modification.

How can I verify the battery is recognised correctly after installation?

Open Lenovo Vantage or the BIOS power tab; the reported capacity should read 76Wh and the part number should show L21C4PH2 or one of the listed SB11 codes.

Does the package include any tools or cables, or is it only the battery?

The box contains only the black lithium-ion battery; no screwdrivers, ribbons or AC adapters are supplied.
