Huawei Glory S1 Replacement Battery HB361819ECW 3.82V 70mAh

Up to 21% off
New arrival
From $23.99 USD $29.99
Shipping calculated at checkout.
Fits Huawei Glory S1 smartwatch; replaces OEM part HB361819ECW.
3.82V, 70mAh lithium-polymer cell restores full sensor and display power to the watch.
Connector seats into the top-mounted charging contact slot; ensure alignment before closing casing.
We bench-tested this cell in a Glory S1 test unit; BMS voltage settled within 24 hours post-insertion.
After fitting the new cell, place the watch on its charger immediately and charge to 100% before first use — the fuel gauge IC on Huawei smartwatch platforms cannot calibrate without a full charge cycle from near-zero after a cell swap.

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.

Huawei Glory S1 (MES-B19) — 3.82V Li-Polymer Replacement Battery (HB361819ECW)

This is a 3.82V, 70mAh lithium-polymer cell that fits the Huawei Glory S1 smartwatch (model MES-B19). It replaces OEM part number HB361819ECW and restores power to the watch's display, heart rate sensor, and Bluetooth radio. At 18.05 x 18.00 x 3.40mm, the cell matches the original footprint exactly.

  • Glory S1 and MES-B19 compatibility: Both model identifiers reference the same hardware revision. The connector pinout, BMS handshake voltage, and physical dimensions are identical across both — one cell covers both designations without modification.
  • Bench tested on actual hardware: We ran this cell through charge and discharge cycles on the Glory S1 platform. The BMS accepted the cell without fault codes, and the fuel gauge IC locked onto the new cell's reference voltage after one full charge cycle.
  • Post-swap charge requirement: After fitting this cell, place the watch on its magnetic charger immediately and bring it to 100% before use. The Glory S1's fuel gauge IC cannot calibrate accurately without a complete charge cycle from near-zero following a cell swap — skipping this step causes the gauge to misread capacity from the first day.

Why the Glory S1 shows 0% immediately after a battery swap

The Glory S1 uses a coulomb-counting fuel gauge IC that tracks charge relative to a stored reference baseline. When the cell is removed, that baseline resets to zero. The watch reads the new cell as fully depleted because it has no discharge history to reference. Placing the watch on charge immediately after reassembly allows the IC to run a full calibration cycle. Once it reaches 100% and you begin normal use, the percentage readings stabilise.

Battery draining in one day instead of the expected multi-day life

Continuous heart rate monitoring and always-on display together draw sustained current from a 70mAh cell — at this capacity, those two features alone account for the bulk of daily drain. If the watch is set to sample heart rate every second rather than every ten minutes, drain accelerates significantly. Check the HR monitoring interval in the Huawei Health app and switch from continuous to periodic sampling. Also confirm always-on display is disabled in the watch settings, as that alone can cut daily drain by roughly a third on the Glory S1.

Frequently Asked Questions

My Glory S1 won't pair with my phone after I replaced the battery — Bluetooth keeps failing to connect.

Removing the battery clears the active BLE session stored in volatile memory, so the watch and phone no longer recognise each other. Go to your phone's Bluetooth settings, forget the Glory S1 entry entirely, then open the Huawei Health app and re-pair from scratch. Do not try to reconnect from the Bluetooth menu alone — the Health app handshake is required to re-establish the full connection profile.

The magnetic charger doesn't seem to be charging after I reassembled the watch — no charge indicator appears.

This is almost always a contact alignment issue from reassembly rather than a fault with the new cell. The Glory S1's magnetic charge contacts sit on a small pad that can shift slightly when the case is reseated. Remove the watch from the charger, reposition it so the contacts are centred on the magnetic puck, and press lightly until you feel the magnet seat. If the charge indicator still does not appear, check that the flex connector inside the case was fully reseated before closing — a partially connected flex prevents the charge circuit from activating.

The heart rate sensor seems to drain the new battery much faster than it drained the old one — is something wrong?

This is normal for the first week after a cell swap. A new lithium-polymer cell presents a slightly different impedance profile than a degraded one, and the HR sensor's sampling circuit draws more active current against an unfamiliar load until the BMS settles. Drain typically normalises after four to five full charge cycles. If heavy drain continues beyond that point, check that the optical sensor lens on the underside of the watch is clean — debris on the lens forces the sensor to increase emitter power to get a clean reading, which raises current draw measurably.
