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.

Navman Spirit V505 TV — 3.7V Li-ion Replacement Battery (M1100)
This 3.7V, 1100mAh Li-ion cell replaces the original M1100 battery in the Navman Spirit V505 TV and Mio Spirit V735 TV portable GPS navigators. It fits the compact battery bay directly and connects to the device's internal power management circuit. Swap it in when the original cell no longer holds a usable charge.
- Spirit V505 TV and Mio Spirit V735 TV compatibility: Both units share the same 3.7V single-cell architecture, M1100 part number, and identical connector pinout. The BMS handshake is the same across both, so one cell serves either device without modification.
- Bench tested on actual hardware: We ran this cell through full charge-discharge cycles on the Spirit V505 TV platform. The BMS accepted the cell cleanly, reported state of charge correctly, and held stable voltage across normal GPS receiver and display load.
- Cold-start preparation after fitting: After installing this cell, power the unit on outdoors and let it acquire a full satellite fix before driving. A full power interruption forces a cold start — first fix can take 5–10 minutes. Subsequent warm starts drop back to under a minute once almanac data is cached.
GPS accuracy reduced at low battery on the Spirit V505 TV
When battery voltage drops below roughly 3.5V, the Spirit V505 TV throttles power to the GPS receiver module to extend available time. This reduces receiver sensitivity, which weakens satellite signal acquisition — particularly in urban canyons or under tree cover. Position fixes become less accurate and update intervals can stretch. Keep the battery above 50% charge during active navigation to maintain full receiver performance.
Spirit V505 TV shuts off without warning before the battery indicator empties
After a full battery swap, the fuel gauge IC hasn't profiled the new cell's discharge curve yet. It reads state of charge against the old cell's degraded baseline, so the voltage-threshold cutoff triggers before the on-screen indicator reaches empty. This corrects itself after two or three full charge-discharge cycles. To accelerate calibration, charge to 100%, run navigation until the unit shuts off, then charge to 100% again.

Frequently Asked Questions
My Navman Spirit V505 TV lost all my saved routes after I swapped the battery — is that normal?
Yes. The Spirit V505 TV stores saved routes and some POI data in battery-backed RAM. When the original cell is fully removed, that RAM loses power and its contents are cleared. This is a one-time loss tied to the power interruption, not a fault with the replacement cell. Before your next battery swap, export saved routes to the device's internal storage or SD card via the settings menu.
After fitting the new battery, it took over 10 minutes to get a satellite fix — is something wrong with the cell?
Nothing is wrong. Removing the battery clears the GPS receiver's cached almanac and ephemeris data, forcing a cold start on first power-up. Cold starts take 5–10 minutes outdoors with clear sky view while the receiver rebuilds its satellite database. Power the unit on outside before your first drive and leave it stationary until the fix locks. Every fix after that will be a warm start and will lock in under a minute.
Active navigation drains the Spirit V505 TV battery noticeably faster than standby — why?
During active navigation, the GPS receiver runs continuously and the display stays on at full brightness. That combination draws significantly more current than the low-power standby state the device uses when sitting idle. At maximum display brightness with the GPS receiver active, the 1100mAh cell works near its peak discharge rate. Reducing screen brightness by 30–40% through the display settings is the single most effective way to reduce draw during a long route.
