Questions about this item
Does the 45N1128 X240 battery pack include a charger or must I buy a 20 V AC adapter separately?
The box contains only the 6-cell Li-ion battery rated at 10.8 V and 48 Wh; a 20 V AC adapter is not included and must be purchased separately if you do not already have one.
How do I choose between the listed part numbers such as 45N1125, 45N1126 and 45N1128 for my ThinkPad?
All listed part numbers — 45N1124 through 45N1144 plus 0C52861 and 0C52862 — refer to the same 10.8 V 48 Wh 6-cell form factor, so any of them will fit the compatible ThinkPad models.
What does the 48 Wh rating mean for real-world runtime on a ThinkPad T450?
The 48 Wh capacity is designed to deliver up to 500 recharge cycles and typically provides several hours of mixed use on a T450, depending on screen brightness, workload and power-management settings.
