Sustained output at 11.52 V and 8120 mAh
Each cell is tested for correct voltage, circuit protection and stable current delivery before shipping. Low self-discharge helps the pack hold charge during storage. CE, FCC and RoHS certifications confirm compliance with safety standards. The 94 Wh rating supports extended work sessions without a mains connection.
Thermals and power draw in normal use
Lithium-ion chemistry keeps heat generation modest during typical office workloads. The slim 12.8 by 3.25 by 0.5 form factor fits the original battery bay without obstructing chassis airflow. At 0.5 lb the pack adds minimal weight. No active cooling is required and the battery operates silently.

Questions about this item
Does the 94 Wh, 6-cell battery run hotter or draw more power than the original 90 Wh pack during all-day workloads?
The replacement matches the original 11.52 V and 94 Wh rating, so thermal output and power draw stay equivalent to the factory pack under sustained load.
My ThinkPad P16 Gen 2 uses the internal 6-cell connector — does this battery plug straight in without an adapter?
Yes, the L21M6P70 uses the same internal connector as OEM part numbers 5B10W51893 and 5B11M90090, so it fits directly into Gen 1 and Gen 2 chassis.
Will the 12.8 × 3.25 × 0.5 inch form factor sit flush in a P16 Gen 1 21D7 that currently holds a 90 Wh battery?
The dimensions match the factory 6-cell pack, so the battery seats flush in every listed P16 Gen 1 and Gen 2 sub-model including the 21D7.
