Direct Replacement for ThinkPad E-Series
This 4120mAh 11.1V lithium-ion battery replaces part numbers L17L3P51, L17C3P51, L17M3P51 and 01AV445 through 01AV448. It fits Lenovo ThinkPad E480, E485, E495, E580, E585, E490, E590, E595 and R480 models. The black pack is a new replacement unit rated at 45Wh.
Capacity Limits for Mobile Workloads
A 45Wh cell delivers a finite runtime that varies with screen brightness, CPU load and connected peripherals. Heavy multi-tasking or discrete graphics use will drain the pack faster than light document work. The 11.1V output matches the original specification so the laptop's power management behaves as designed.
Upgrade from Depleted Original Cells
When an original battery no longer holds charge or shuts down under load, this unit restores full mobile operation. The jump is worth it if the laptop otherwise meets your needs and the chassis is in good condition. It does not add capacity beyond the factory 45Wh rating.

Questions about this item
Which part number should I pick for my ThinkPad E480 — L17M3P52, L17L3P51 or L17C3P51?

Yes, the 11.1V specification matches the voltage required by the R480 series and the connector is designed for the listed Lenovo models.
