Battery Care Tips
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
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.

Garmin Vivoactive HR — 3.7V Li-Polymer Replacement Battery (361-00090-00)
This 3.7V, 180mAh Li-Polymer cell is a direct swap for the original battery in the Garmin Vivoactive HR smartwatch. It fits the wrist-worn GPS fitness tracker that runs continuous heart rate monitoring, activity tracking, and smart notifications. Dimensions are 36.40 × 19.80 × 3.20mm — match these before ordering.
- Vivoactive HR fitment: The Vivoactive HR uses a dedicated battery bay sized for this exact cell profile. The flex connector locks to the same board header as the OEM unit, so no adapter or re-pinning is needed.
- Bench tested on actual hardware: We ran this cell on a Vivoactive HR with GPS active and continuous wrist HR enabled. The BMS accepted the charge handshake without error on the first connection and held steady voltage through full charge and discharge cycles.
- Fuel gauge recalibration after swap: After fitting this cell, place the watch on its magnetic charger immediately and charge to 100% before first use. The fuel gauge IC on the Vivoactive HR cannot set an accurate reference point without a complete charge cycle from near-zero following a cell swap — skipping this step causes false low-battery readings.
Why the Vivoactive HR shows 0% straight after a battery swap
The Vivoactive HR uses a coulomb-counting fuel gauge IC that tracks charge relative to a stored reference. Removing the old cell clears that reference entirely. When a new cell is fitted, the IC has no baseline, so it defaults to 0% or reports an incorrect state of charge. Charging to 100% immediately after installation resets the reference register and restores accurate percentage readings. Do not skip this step even if the watch powers on and shows activity.
Watch not pairing to phone after battery replacement
Removing the battery kills the active Bluetooth session stored in the watch's memory. The phone retains a paired device entry, but the watch no longer recognises it as an active bond. Go into the Garmin Connect app, remove the Vivoactive HR from paired devices, then re-pair from scratch through the watch's settings menu. This takes under two minutes and fully restores notification and sync functions.

Frequently Asked Questions
My Vivoactive HR battery drains completely within a single day after fitting a new cell — is the new battery faulty?
This is almost always a sensor calibration issue, not a faulty cell. After a cell swap, the always-on heart rate sensor runs at elevated current draw while the new battery's impedance profile settles — this typically normalises within five to seven days of normal use. Check that continuous HR monitoring and GPS are not both set to always-on simultaneously, as that combination significantly increases draw on a 180mAh cell. If drain continues beyond one week, charge to 100%, then check battery percentage after a full 24-hour cycle without GPS active.
The magnetic charger does not seem to be charging the watch after I replaced the battery — the charging icon never appears.
This is almost always a contact alignment issue caused during reassembly. The charging pogo pins on the watch back must sit flush against the rear case — if the case is not fully re-seated and clicked down, the pins lift slightly and lose contact with the charger. Re-open the watch, press the back panel firmly until you hear it click at all four corners, then re-seat the charger. If the icon still does not appear, clean the charging contacts on both the watch and the cable with a dry cloth and try again.
GPS tracking seems to drain the Vivoactive HR battery much faster than heart rate monitoring alone — is this normal for this cell?
Yes, and the difference is significant. The GPS receiver in the Vivoactive HR draws several times more current than the optical HR sensor. This 180mAh cell reflects that tradeoff — multi-day battery life is achievable with HR-only tracking, but active GPS sessions reduce that considerably. To extend GPS session life, disable wrist HR while GPS is active; running both simultaneously is the highest-draw state this watch supports.
