🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.

Battery model: L15D2K31
Capacity: 6200mAh / 23.56Wh
Rated voltage: 3.8V
Charge limit voltage: 4.35V
Battery type: Li-ion Polymer (Grade A cells)
Compatible with: Lenovo Yoga Tab 3 8 (YT3-850, YT3-850F, YT3-850L, YT3-850M)
Package include: 1 x battery
Restore the legendary battery life of your Lenovo Yoga Tab 3 8 with this L15D2K31 6200mAh replacement battery. The Yoga Tab 3 8 (YT3-850 series) was known for its unique built-in kickstand, cylindrical battery compartment design, and the massive 6200mAh battery that delivered up to 20 hours of mixed usage — one of the longest-lasting Android tablets of its generation. This Li-ion Polymer battery restores the full 6200mAh capacity, bringing back the extended video playback and reading sessions that made this tablet special. Built with grade A cells and multi-layer safety protection against overcharge, over-discharge, and short circuits. CE, RoHS, and UN38.3 certified.
What Makes Yoga Tab 3 8 Different — And Why Battery Replacement Matters: The Lenovo Yoga Tab 3 8 features a unique cylindrical hinge that houses the battery and doubles as a built-in kickstand and a handle for comfortable holding. This design allows the tablet to stand in multiple orientations (tilt, hang, hold) — a feature no other tablet offers. The L15D2K31 battery sits inside this cylindrical chamber, using a flexible flat cable connection to the main board. After 6-7 years of use, the original battery likely shows signs of degradation: the tablet no longer lasts through a full day of use, shuts down at 15-20% battery remaining, takes significantly longer to charge, or the kickstand hinge feels loose (sometimes caused by battery swelling). This replacement battery restores the full 6200mAh capacity — letting you enjoy 10+ hours of video playback and 15+ hours of web browsing again. For Yoga Tab 3 8 owners who still appreciate this unique tablet with its built-in stand and the cylindrical battery design, a battery replacement is far more economical than buying a new tablet.
Compatibility & Charging Dock Note: Fits Lenovo Yoga Tab 3 8 models YT3-850, YT3-850F (Wi-Fi), YT3-850L (LTE), and YT3-850M. Please confirm your battery model before ordering — L15D2K31 is printed on your original battery. This battery is NOT compatible with Yoga Tab 3 Plus (YT-X703), Yoga Tab 3 Pro (YT3-850 different battery), or Yoga Smart Tab (YA8 series). The Yoga Tab 3 8 also has an optional charging dock accessory that contacts the cylindrical hinge — this battery works perfectly with that dock. If your tablet no longer holds a charge for a full day of reading or video, this L15D2K31 replacement battery will restore the original performance.

The Yoga Tab 3 8 has a unique cylindrical hinge that houses the L15D2K31 battery — this is different from standard tablets where the battery sits flat.

The battery is connected via a small 2-pin connector inside the hinge. For L15D2K31 battery installation Lenovo YT3-850, the process requires special care because the cylindrical hinge also contains the kickstand mechanism and charging port.

For Lenovo Yoga Tab 3 8 battery health maintenance: 1) Use a standard 5V/2A charger — the tablet does not support fast charging beyond 10W. 2) The optional charging dock is safe to use and convenient, but avoid leaving the tablet on the dock continuously for weeks. 3) Keep battery level between 20% and 80% for daily use to maximize the lifespan of the 6200mAh cell. 4) Avoid exposing the tablet to high temperatures (above 40°C / 104°F) — the cylindrical battery design traps heat more than flat batteries. 5) For long-term storage (over 2 months), keep the battery at approximately 60% charge. 6) Perform a full calibration cycle after installation: drain the tablet until it auto-shuts off, then charge uninterrupted to 100% using the original charger. For Yoga Tab 3 8 battery care tips, stop using immediately if the battery shows any swelling — swelling in the cylindrical chamber can crack the hinge mechanism.
