Replacement Battery for Lenovo IdeaPad Flex 3

This 11.52V 47Wh lithium-ion pack replaces the original Lenovo battery in compatible IdeaPad Flex 3 Chrome 15IJL7 and 300e Chromebook 3rd Gen devices. It is a direct plug-and-play module designed for owners whose factory cell no longer holds a useful charge. Buyers needing a higher-capacity cell or a different form factor cannot use this unit.

Installation Notes and Common Issues

The battery uses a plug-and-play connector so no soldering is required, but the back case must be opened to swap the module. Verifying the exact part number printed on the original battery — such as L20M3PG0, SB11B36311 or 5B11B36312 — before ordering prevents mismatches. Skipping the manual or forcing the connector can damage the mainboard header.

Capacity and Runtime Expectations

The 47Wh 4080mAh rating restores the runtime the laptop delivered when new, supporting typical classroom or office workloads through a full day. Heavy multitasking, maximum screen brightness or continuous video playback will drain the pack sooner. Users who need significantly longer unplugged sessions would require a higher-capacity design that does not exist for this chassis.
