Lenovo Yoga Tablet 2-1051L L14C3K31 Replacement Battery 3.75V 9200mAh

Lenovo Yoga Tablet 2-1051L / 1050L — 3.75V Li-ion Replacement Battery (L14C3K31)

This is a 3.75V, 9200mAh (34.5Wh) Li-ion replacement battery for the Lenovo Yoga Tablet 2 series — specifically the 1051L, 1050L, 1051F, and 1050F. It uses OEM part numbers L14C3K31 and L14D3K31. If the original cell no longer holds a charge or fails to power the tablet, this is the direct replacement.

• Yoga Tablet 2 cross-model fit: The 1051L, 1050L, 1051F, and 1050F all share the same 3.75V battery bay, connector pinout, and BMS communication protocol — that's why one cell covers all four variants without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Yoga Tablet 2 platform. The BMS handshake completed correctly, charge termination triggered at capacity, and the protection circuit responded normally to over-discharge conditions.
• Post-install calibration on Yoga Tablet 2: After fitting the new cell, run the tablet down until it shuts off automatically, then charge uninterrupted to 100% without using it. This resets the fuel gauge IC against the new cell's actual capacity and clears the inaccurate battery health warning the OS often throws after a cell swap.

Why the Yoga Tablet 2 reports poor battery health immediately after a cell swap

The Yoga Tablet 2 stores charge cycle count and health data in the battery's EEPROM. When a new cell goes in, the OS reads that blank or mismatched EEPROM data and flags the battery as unknown or poor health — not because the cell is faulty, but because the fuel gauge IC has no reference point yet. Running one full discharge-to-shutdown followed by a complete uninterrupted charge gives the fuel gauge IC the data it needs. After two to three cycles, reported health and capacity figures stabilise and the warning clears.

This is a voltage cliff issue, not a capacity problem. When the cell ages, it can no longer maintain voltage under the combined load of the display, processor, and Wi-Fi radio — even when the fuel gauge still shows charge remaining. The tablet's protection circuit reads the voltage drop as a low-battery condition and initiates shutdown before the displayed percentage reaches zero. A new cell resolves this immediately — verify by checking that battery voltage under load stays above 3.4V during normal use.
