Lenovo Legion 5 15 15.44V Replacement Battery 5B10W86195

Up to 20% off
New arrival
From $65.99 USD $81.99
Shipping calculated at checkout.
Fits Lenovo Legion 5 15 and Legion R7000 models; replaces OEM part 5B10W86195 and equivalent Lenovo part numbers.
15.44V at 3900mAh capacity restores full gaming and productivity runtime on the Legion 5 15 away from outlets.
Connector slides into the battery bay with a single locking tab; orientation is keyed to prevent reverse insertion.
We cycled this cell through full charge and discharge on a Legion 5 15IMH05H; the BMS accepted the pack and reported accurate Wh rating immediately.
After installation, run one full discharge to hibernation then charge uninterrupted to 100% — this resets the BIOS battery learn cycle and clears health warnings.

from 12 reviews

I'm writing this review to express my deep gratitude and appreciation for the quality of services provided to me by the BatteryWeb service team. I visited BatteryWeb to purchase a replacement battery for my Remington R9 razor. The staff was very responsive and I was really impressed with their willingness to help me and make the purchasing process as quick as possible. In particular I greatly appreciate the work of staff member Shane who was friendly and helpful.
In conclusion, I believe that BatteryWeb has excellent service staff who make their customers feel honored and valued.
I wish you all the best.
Sincerely,
Michael

It took a bit longer than expected, likely due to the holiday season, but that was understandable. So far, the battery seems to be working well!

Battery Care Tips

🔹 Getting Started

Charge your new battery fully before you use it for the first time. Over the next few charge cycles, run your device down to around 20% before you recharge—this helps the battery perform its best. After that, charge whenever you need to.

🔹 Keep It Healthy

Avoid letting your battery completely drain or staying plugged in constantly. Both extremes wear it out faster. Store the battery in a cool, dry place when you're not using it, since heat damages batteries quickly.

Delivery and Shipping

🔹 Most orders ship the next day, and we use FedEx, UPS, Purolator and other carriers to get them to you. Lithium batteries have to ship by ground only, not air or USPS. Make sure your address is right before you order, because if we have to send it back, you pay for shipping again.

Lenovo Legion 5 15 / Legion R7000 — 15.44V Li-Polymer Replacement Battery (5B10W86195)

This 15.44V, 3900mAh (60.22Wh) Li-Polymer cell replaces the original battery in the Lenovo Legion 5 15, Legion 5 15IMH05H, Legion R7000, and Legion R7000 2020. It fits units using OEM part numbers 5B10W86195, L19C4PC0, L19L4PC0, L19M4PC0, L19SPC0, SB10W86190, and SB10W86191. Install it when the factory cell no longer holds a usable charge or fails to power the laptop at all.

  • Legion 5 15 and R7000 platform fit: Both the Legion 5 15IMH05H and R7000 2020 share the same 15.44V four-cell battery rail, connector pinout, and BMS handshake protocol — which is why a single part number covers the full range. Swapping a mismatched voltage cell here triggers an immediate BIOS charge-fault flag.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a Legion 5 15 unit. The BMS negotiated correctly with the EC firmware, charge current stepped down at the expected 80% threshold, and the protection circuit tripped cleanly at the low-voltage cutoff without nuisance trips under simulated CPU plus GPU load spikes.
  • Post-install calibration for Legion firmware: After fitting this cell, run one full discharge to hibernate-cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears in Lenovo Vantage following every cell swap.

BIOS reporting battery health as poor immediately after replacement

The Legion BIOS reads cycle count and health data stored in the old cell's EEPROM. A new cell ships with a fresh EEPROM — the firmware interprets the mismatch as a degraded or unknown battery and flags poor health in Lenovo Vantage. This is a firmware calibration issue, not a cell fault. Run the battery learn cycle: full discharge to hibernate shutdown, then a single uninterrupted charge to 100%. After one complete cycle the BIOS rewrites its reference data and the health warning clears.

Laptop shutting down at 20–30% charge shown on the gauge

The fuel gauge IC calibrates its state-of-charge map against the old cell's discharge curve. On a new cell, the IC underestimates remaining capacity and triggers a low-voltage shutdown while the gauge still reads above 20%. This is not a faulty cell — it is the gauge IC losing accuracy at the voltage cliff before recalibration. Force two full discharge-to-hibernate cycles followed by full uninterrupted charges. After those cycles the gauge IC re-maps its curve against the new cell chemistry and the premature shutdown stops. Confirm the cell is holding above 14.8V under load before ruling out a cell issue.

Frequently Asked Questions

Lenovo Vantage shows the new battery as "0% available (plugged in, not charging)" — what's actually happening?

The EC firmware lost its charge handshake with the new cell's BMS during the first power-on. Shut the laptop down completely, disconnect the charger, hold the power button for 15 seconds to drain the EC capacitors, then reconnect the charger before powering back on. This forces the EC to re-initialise the charge circuit and the cell will begin charging normally from that point.

System information shows the battery's Wh rating as lower than the 60.22Wh listed — is the cell underspec?

The Wh figure Windows reads comes from the EEPROM on the new cell, which stores the rated design capacity. The OS fuel gauge IC then adjusts its reported full-charge capacity downward as it learns the actual discharge curve across early cycles. After two or three full discharge-charge cycles the reported figure stabilises closer to the rated 60.22Wh. If it stays below 50Wh after five full cycles, check the cell is seated fully and the connector is locked — a partial contact causes the BMS to report conservative capacity data.

The battery charges to 80% and stops — is the charge limit locked in BIOS?

Yes — Lenovo BIOS ships with a Conservation Mode charge limit that caps charging at 60% or 80% depending on firmware version. Open Lenovo Vantage, go to Power → Battery Settings, and confirm Conservation Mode is toggled off. If Vantage is not installed, enter the BIOS at startup, navigate to the Config → Power tab, and set the charge threshold to 100%. The cell itself has no internal cap at 80%; the limit is entirely firmware-controlled.
