Lenovo 45N1124 T440s 24 Wh Battery | ThinkPad Replacement Power

Keep a Lenovo ThinkPad T440s working the way mobile teams expect with this replacement battery. Built around a 3-cell lithium-ion design, it delivers 24 Wh of capacity and 11.40 V output, giving users a practical power source for short unplugged sessions, quick transitions, and backup runtime when AC access is limited. This battery is a fit for organizations that need to restore notebook mobility without changing the device platform. It is well suited to service desks, spare-parts programs, and lifecycle support for T440s deployments where battery wear is the most common cause of reduced field productivity. The compact form factor supports the slim profile of the system while keeping replacement straightforward. Compared with generic alternatives, a model-specific battery helps reduce compatibility risk and keeps procurement aligned with the original notebook design. For IT teams supporting premium business laptops, that matters: predictable fit, known electrical characteristics, and a direct replacement path that preserves the user experience.
