Replacement battery for Lenovo Legion 15-inch models

This lithium-ion battery delivers 11.25V and 52.5Wh of capacity for compatible Lenovo Legion Y530, Y540, Y545, Y740 and Y7000 2019 series laptops. It replaces part numbers including L17M3PG1, L17C3PG1, L17C3PG2 and 5B10Q82428. The pack is new and ships in black with an instruction sheet. Buyers needing a battery for the Legion Y7000 2020 series should look elsewhere as this model is not compatible.

Thermals and power draw in daily use

The 4670mAh cell provides standard operating voltage for the supported 15-inch chassis without increasing heat output beyond the original specification. Normal office workloads and media playback draw power at the rate the laptop's power management expects. No additional cooling or configuration changes are required after installation.

Behaviour under sustained load

During extended gaming or rendering sessions the battery maintains the rated 11.25V output until depletion, matching the discharge profile of the factory pack. Capacity remains at 52.5Wh throughout the cycle rather than dropping sharply after a short burst. Users running continuous high-wattage workloads should still connect the AC adapter for uninterrupted operation.

Questions about this item

How do I install the L17M3PG1 battery and which step is often missed?

Power off the laptop, remove the bottom cover, disconnect the old battery connector, fit the new 11.25V pack, reconnect the cable, and replace the cover. The step people miss is disconnecting the old battery before fitting the new one.

What maintenance or replacement will the L17M3PG1 need later?

The lithium-ion cell will gradually lose capacity; plan to replace the pack when runtime no longer meets your needs. No user-serviceable parts are inside.

What limit appears first on the L17M3PG1 during sustained use?

The 52.5Wh capacity sets the runtime ceiling; under continuous load the pack will deplete to its low-voltage cut-off and the laptop will shut down.
