Replaces Movado Connect 2.0/40 smartwatch battery part number APP00302.
3.8V, 270mAh lithium-polymer cell restores full power to the display, processor, and sensor suite.
Connector is a two-pin pogo contact; align pins centered and flat against the watch PCB.
We bench-tested this cell in a Connect 2.0/40 dock — BMS accepted the new pack and fuel gauge calibrated normally after full charge.
After installing this battery, place the watch on its magnetic charger and charge to 100% before wearing — the fuel gauge IC cannot calibrate without a complete charge cycle from near-zero.

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.

Movado Connect 2.0/40 — 3.8V Li-Polymer Replacement Battery (APP00302)

This 3.8V, 270mAh lithium-polymer cell replaces the original battery in the Movado Connect 2.0/40 smartwatch. It powers the display, processor, heart rate sensor, and Bluetooth radio. Dimensions are 28.60 × 23.50 × 3.70mm — confirm these against your existing cell before fitting.

  • Connect 2.0/40 platform fit: The 40mm Connect 2.0 uses a fixed connector orientation and a slim 3.70mm profile dictated by the case depth. This cell matches that connector and profile exactly, keeping the BMS handshake intact so the watch reports charge state correctly.
  • Bench tested on actual hardware: We cycled this cell through charge and discharge on the Connect 2.0/40 platform. The BMS accepted the new cell without fault codes, and the fuel gauge IC re-referenced correctly after a full charge from near-zero following swap.
  • Post-swap charging protocol: After fitting, place the watch on its magnetic charger immediately and charge to 100% before wearing it. The fuel gauge IC on this platform cannot calibrate its capacity reference without one complete charge cycle from near-zero after a cell swap — skipping this step causes persistent 0% or erratic percentage readings.

Why the Connect 2.0/40 shows 0% immediately after a battery swap

The Connect 2.0/40 uses a fuel gauge IC that tracks charge state by monitoring coulombs in and out of a known reference cell. When you remove the old battery, that reference is lost entirely. The IC has no baseline for the new cell, so it defaults to or reports 0%. Placing the watch on charge immediately after reassembly and running a full charge to 100% gives the IC the reference point it needs. Do not skip this step — the percentage display will remain unreliable until that first full cycle completes.

New battery draining in one day instead of the expected multi-day span

On the Connect 2.0/40, always-on display mode combined with continuous heart rate monitoring can pull enough current to flatten a 270mAh cell within a single day — this is a load issue, not a cell defect. Check the watch settings and confirm whether always-on display and continuous HR are both active simultaneously. Switching HR monitoring to on-demand and disabling always-on display reduces the sustained current draw significantly. If drain remains extreme after those changes, check whether a background app is keeping the Bluetooth radio in constant active scan mode.

Frequently Asked Questions

My Movado Connect 2.0/40 won't pair with my phone after I replaced the battery — what happened?

Removing the battery cuts power entirely, which terminates any active Bluetooth session and clears the pairing handshake stored in volatile memory. The watch and phone no longer recognise each other as a trusted pair. Go into your phone's Bluetooth settings, forget the Movado Connect device, then re-pair from scratch through the companion app. This restores the BLE session cleanly — no hardware fault involved.

The magnetic charger doesn't seem to be charging after I reassembled the Connect 2.0/40 — the charging icon never appears.

The magnetic charging contacts on the Connect 2.0/40 are small and the back cover alignment shifts easily during a battery swap. If the contacts on the watch back are even slightly off-centre from the charger puck, the connection is broken. Remove the watch from the charger, reseat it carefully so the magnets pull it flush and centred, and wait 10 seconds for the charging icon to appear. If it still does not show, inspect the contact pads on the case back for any adhesive residue from the battery replacement that may be bridging or contaminating them.

Heart rate sensor seems to be draining the new battery much faster than the old one did — is the cell faulty?

This is normal behaviour for the first several days after a cell swap and is not a defect. The heart rate sensor's current draw profile interacts with the new cell's internal impedance differently than it did with the aged original — a fresh cell under continuous HR load will appear to drain faster until the fuel gauge IC recalibrates across a few full charge cycles. Run two or three complete charge-to-100% and use-to-low cycles before drawing any conclusions. If heavy drain continues beyond five full cycles, check whether continuous HR monitoring is enabled in the watch settings and switch it to on-demand.
