Direct replacement for IdeaPad 3 series

This 45Wh lithium-ion battery replaces part numbers L19C3PF7, L19L3PF5, L19D3PF5 and 31CP6/54/90 in compatible Lenovo IdeaPad 3 14 and 15 inch models. It is intended for owners whose original pack no longer holds a useful charge.

Runs at 11.34 volts with standard Li-ion thermals

The cell chemistry operates at the factory voltage of 11.34V and produces heat and noise levels consistent with the original equipment battery. No additional cooling or power draw considerations apply beyond normal laptop use.

Capacity of 45Wh decides runtime

The 45 watt-hour rating determines how long the system runs on battery power; buyers needing longer unplugged time should look for a higher-capacity alternative if their chassis supports it.

Questions about this item

How do I install the L19C3PF7 L19L3PF5 L19D3PF5 battery in my IdeaPad 3 14" and which step is often missed?

Power off the laptop, unplug the AC adapter, remove the base screws, disconnect the old battery cable before lifting it out, connect the new battery cable firmly, then reassemble; the step most often missed is disconnecting the old battery cable first.

What maintenance or replacement will the 45Wh lithium-ion battery need later?

The 45Wh lithium-ion battery will eventually hold less charge; when runtime becomes too short, replace it with another 11.34V 45Wh pack such as part numbers L19C3PF7, L19L3PF5, L19D3PF5 or 31CP6/54/90.

What limit appears first during sustained use of the 11.34V battery?

Under sustained load the 45Wh capacity is the first limit; the battery will discharge until the laptop shuts down or throttles to protect the 11.34V cells.
