90 Wh Li-polymer battery for ThinkPad P50 P51 P52

This replacement battery delivers 11.25 V and 90 Wh capacity for ThinkPad P50, P51 and P52 series laptops. It uses lithium-polymer cells and replaces multiple FRU and ASM part numbers including 00NY492 and SB10H45078. The unit is supplied new from the manufacturer and rated for up to 500 recharge cycles over its service life.

Upgrades from lower-capacity 77 Wh packs

The battery replaces the standard 77 Wh and 77+ Wh packs originally fitted to these workstations. The jump to 90 Wh is worthwhile when longer unplugged runtime is needed for field work or travel. It fits the same chassis without modification and uses the existing charge controller.

Sustained output matches original thermal envelope

Under continuous load the pack maintains its rated voltage without throttling the system beyond the limits of the original battery. Cell chemistry and firmware are tuned for stable discharge across the full capacity range. The 12-month manufacturer warranty covers defects in materials and workmanship.

Questions about this item

Will this 90Wh battery fit my ThinkPad P51 without any case modifications?

Yes, it is built to the same dimensions as the original 00NY492 and SB10H45077 packs used in the P50, P51 and P52 series.

What is the correct way to install the battery and what step do people often skip?

Power off the laptop, disconnect the AC adapter, remove the bottom cover, unplug the old pack, connect the new 11.25V battery, refit the cover, then charge to 100% before first use — skipping the full initial charge is the common mistake.

How many recharge cycles can I expect before the 90Wh capacity drops noticeably?

The manufacturer rates the lithium-polymer cells for up to 500 full recharge cycles over the battery's life.
