Direct replacement for ThinkPad P53

This 90Whr 6-cell lithium-ion battery matches the 11.25V specification of the original Lenovo units. It fits the ThinkPad P53 models 20QN and 20QQ and replaces part numbers including 02DL028, 02DL029, L18M6P90 and SB10K97664. The pack is built with GreenTech cells and carries CE, FCC and RoHS certification.

Fits without modification

The battery slides into the existing bay on the compatible ThinkPad P53 chassis, using the original connector and screw positions. No adapter cables, BIOS updates or chassis changes are required. Swapping the pack restores full mobile operation and frees the user from staying tethered to an AC outlet during work sessions.

Tested for stable output

Each unit is tested before shipping to verify correct voltage, circuit protection and low self-discharge. In normal use the 6-cell design delivers steady current at 11.25V without excessive heat buildup. The lithium-ion chemistry keeps operating noise at zero while maintaining the rated 8000mAh capacity through daily charge cycles.
