Replacement battery for ThinkPad L450

This Cameron & Co lithium-ion battery is built to fit a wide range of Lenovo ThinkPad models including the L450, L470, T440, T440s, T450, S440 and S540. It replaces original part numbers such as 45N1124, 45N1125, 0C52861 and 0C52862. The unit ships new in black and is intended for owners who need a direct swap for a worn-out internal pack.

Who this suits and who should look elsewhere

It suits anyone restoring battery life to the listed ThinkPad laptops without opening the chassis for modifications. It will not help users whose machines require a different form factor, a higher capacity than 4.4 Ah, or an external power bank instead of an internal cell. Buyers with non-ThinkPad hardware or models outside the compatibility list should seek the correct part for their device.

Capacity and practical headroom

The 4.4 Ah rating delivers a full day of typical office work on a healthy ThinkPad T440s or L450, covering web browsing, document editing and video playback. Runtime drops noticeably under sustained heavy loads such as compiling code or driving an external display at maximum brightness. The pack does not extend beyond this capacity, so users needing multi-day autonomy without charging should plan for a spare unit or a dock.
