Lenovo 45N1126 Battery 11.4 V 2.06 Ah 24 Wh | ThinkPad T440s

Keep a ThinkPad T440s in service with a battery designed to match the original platform requirements. Lenovo part number 45N1126 is a 3-cell lithium-ion pack rated at 11.4 V, 2.06 Ah, and 24 Wh, giving IT teams a straightforward replacement path for aging or degraded batteries. For fleet support, the value is consistency. OEM sourcing helps reduce compatibility risk, simplifies spares planning, and supports a cleaner refresh cycle for mobile users who depend on stable runtime during travel, meetings, and remote work. When battery health drops, performance suffers long before the device itself reaches end of life. Replacing the pack restores practical mobility without forcing a full system replacement. This battery fits the needs of organizations that still rely on ThinkPad T440s systems for field work, executive support, or controlled endpoint deployments. It is a targeted component purchase that protects productivity, extends useful device life, and avoids the cost of premature hardware retirement.
