Replacement Battery for ThinkBook 13s and 13x Series

This 15.52V lithium-ion pack replaces part numbers L21B4PD0, L21C4PD0 and L21M4PD0 in Lenovo ThinkBook 13s G4 ARB, 13s G4 IAP, 13x G2 IAP and Plus G4 IRU models. It restores factory power specifications for users whose original cell has degraded.

56 Wh Capacity and 15.52 V Output

The 56 Wh rating delivers typical all-day office runtime on a single charge for the supported ultraportables. Heavy workloads such as sustained video export or virtual machines will drain the cell faster and require mid-day recharging.

Direct Fit for 21AS, 21AR, 21AT and 21JJ Chassis

The black pack slides into the internal battery bay without adapters and connects to the existing motherboard header. No external charger or cable routing is needed, freeing the USB-C port for peripherals or display output.

Questions about this item

Will this 56Wh 15.52V battery fit the original connector on my ThinkBook 13s G4 IAP without an adapter?

Yes, it replaces part numbers L21B4PD0, L21C4PD0 and L21M4PD0 used in ThinkBook 13s G4 IAP (Type 21AR) so the connector matches the original.

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

Power on the laptop; the OS battery icon should show 15.52V design voltage and 56Wh capacity, and the charge percentage should increase while plugged in.

What comes in the package and do I need any extra screws or cables?

The box contains one battery only; no screws, cables or tools are included, so reuse the fixings from your old battery.
