Lenovo 45N1767 Notebook Battery 10.8 V 48 mAh | ThinkPad

Keep compatible ThinkPad notebooks in service with a replacement battery built for practical fleet support. The Lenovo 45N1767 is a rechargeable lithium-ion notebook battery rated at 10.8 V DC and 48 mAh, intended for use in Lenovo ThinkPad X240 and T440s systems. For IT teams, a known-good replacement battery helps reduce support delays, simplify spare inventory, and extend the useful life of deployed laptops. This battery is a straightforward choice when you need a direct replacement rather than a low-cost substitute with uncertain fitment. Matching the original electrical profile helps maintain charging behavior and system compatibility, which matters in managed environments where consistency is more valuable than speculation. It is also a practical option for organizations that keep spare batteries on hand for desk-side support, depot repair, or mobile workers who need a quick swap. For procurement, the value is in standardization. A verified Lenovo part number makes it easier to align purchasing, service, and asset management around one replacement path. For end users, it means less time tethered to AC power and more time working where the notebook is needed.
