Replacement battery for ThinkBook 14 and 16

This GreenTech battery replaces multiple Lenovo OEM part numbers for ThinkBook 14 G6, G7 and 16 G6, G7 models. It is a three-cell lithium-ion unit rated at 11.55V and 45Wh. The pack fits K14 G2 and G3 variants as well as the listed ThinkBook series.

Direct OEM replacement with tested safety

The battery ships without extra cables or software; it is a straight swap for the original pack. Each unit is tested for correct voltage, circuit protection, stable current and low self-discharge. It carries CE, FCC and RoHS certifications for safety compliance.

45Wh capacity for typical office workloads

At 3900mAh the pack delivers enough energy for a full day of light productivity on compatible 14-inch and 16-inch ThinkBooks. Heavy multi-tasking or high screen brightness will reduce runtime. Users needing longer unplugged sessions should consider a higher-capacity alternative.

Questions about this item

How many charge cycles can the 3-cell lithium-ion pack deliver before it needs replacing?

The 3-cell lithium-ion pack is rated for typical cycle life; capacity will gradually drop after several hundred full cycles, at which point a replacement restores full runtime.

What limits runtime first during a continuous heavy workload on the 45Wh battery?

The 45Wh capacity and 3900mAh rating set the energy ceiling, so sustained high drain depletes the charge before any thermal throttle engages.

Does the 11.55V battery generate noticeable heat or fan noise when the laptop runs all day?

The battery itself produces minimal heat; any warmth or fan activity comes from the laptop's processor and cooling system, not from the pack.
