A reliable GPS is essential for road trips and backcountry exploration alike. However, over time, internal Lithium-ion batteries lose their ability to hold a charge. Because manufacturers like Garmin and TomTom use hundreds of proprietary battery shapes, finding the exact match is critical. This guide breaks down compatibility for the industry’s leading brands.
Why GPS Battery Compatibility Matters
Choosing the wrong battery for your navigation device isn’t just about it not fitting—it’s a performance and safety issue.
Risks of using the wrong battery
An incompatible battery can cause your GPS to “boot loop” (constantly restart) or fail to acquire a satellite signal due to insufficient voltage. In extreme cases, a mismatched connector can short-circuit the motherboard.
Voltage and connector differences
While most GPS batteries operate at 3.7V, the physical connectors vary wildly. Some use 2-pin, 3-pin, or even 5-pin JST-style plugs. Using a 2-pin battery on a 3-pin device may disable the “charging” indicator or temperature sensor.
Impact on device performance and safety
GPS units are often mounted on windshields under direct sunlight. A low-quality or incompatible battery is more prone to swelling or leaking under high-heat conditions, posing a fire risk to your vehicle.
How to Identify Your GPS Battery Model
1. Check the battery label and part number
If you can open your device, look for a Part Number (P/N). For Garmin, these usually look like 361-00019-11. For TomTom, look for codes like AHL03713000.
2. Identify by GPS device series
Check the bottom or back of the GPS casing for the model name (e.g., Garmin Nuvi 2597LMT or TomTom GO 520). Note that “LMT” or “S” suffixes often don’t change the battery type, but the series number does.
Garmin GPS Battery Compatibility Chart
Garmin has one of the largest ecosystems of battery types. Below are the most common matches:
| Series | Common Models | Common Battery P/N |
|---|---|---|
| Nuvi Series | 200, 300, 1300, 1400, 2400 | 361-00019-11 / 361-00051-02 |
| Drive Series | Drive 50, DriveSmart 61, DriveAssist | 361-00056-00 / 361-00056-50 |
| Outdoor Series | Montana 600, 650, 700 / Oregon / eTrex | 010-11654-03 (Lithium Pack) |
| Zumo Series | 390, 395, 590, 595 (Motorcycle) | 361-00059-00 |
TomTom GPS Battery Compatibility Chart
TomTom batteries are often thinner and use specialized flat-ribbon or 3-wire connectors.
- TomTom GO Series: Models like the GO 500, 600, and 5000 often require high-capacity 3.7V Li-ion cells (P/N: VF3A).
- TomTom VIA Series: The VIA 1405, 1505, and 1535 use a very specific rectangular cell (P/N: AHL03714000).
- TomTom ONE / XL / XXL: These older models are popular for refurbishing and typically use the AHL03713000 model.
Are GPS Batteries Interchangeable Between Brands?
The answer is No. Even if a Garmin and a TomTom battery look identical in size:
- Connector Polarities: Manufacturers often reverse the red (positive) and black (negative) wires in the plug. Connecting the wrong one will instantly kill the device.
- Smart Protection Circuits: Most GPS batteries include a PCB (Protection Circuit Board). A Garmin device expects a specific signal from this board that a TomTom battery won’t provide.
Signs Your GPS Battery Needs Replacement
- Sudden Shutdown: The GPS turns off the moment you unplug the car charger.
- “Battery Low” Loop: The device shows a low battery warning even after being plugged in all night.
- Case Bulging: If the screen starts to lift or the back casing feels rounded, the battery has swollen and is dangerous.
Buying Guide: Choosing the Right Battery
- Voltage: Must match (usually 3.7V).
- Capacity (mAh): You can use a higher mAh for longer unplugged life, but only if the physical size remains the same.
- Third-Party vs. OEM: Since Garmin and TomTom rarely sell internal batteries to consumers, high-quality third-party brands are often the only option. Look for CE and RoHS certification.
Tips to Extend GPS Battery Life
1. Avoid Sunlight: When parked, remove the GPS from the windshield. Heat is the #1 killer of Lithium batteries.
2. Partial Discharges: Don’t leave the GPS at 0% for months. Charge it to around 50% if you’re putting it in storage for the winter.
