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.

Magellan RoadMate 2230 / 2230T-LM — 3.7V Li-ion Replacement Battery (338040000014)
This 3.7V, 750mAh Li-ion cell replaces the OEM battery in the Magellan RoadMate 2230 and RoadMate 2230T-LM portable GPS navigators. It matches the original 338040000014 part number and fits the same 50.55 × 36.39 × 5.73mm footprint. Swap it in when the unit no longer holds a charge or shuts off during navigation.
- RoadMate 2230 and 2230T-LM fit: Both variants share the same internal battery bay, connector pinout, and charge circuit. One cell covers both.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the RoadMate platform. The protection circuit triggered correctly at low-voltage cutoff and accepted a full charge without fault flags from the device.
- First fix after power interruption: After fitting this cell, power the unit on outdoors before driving. A cold start — triggered any time the GPS loses all power — can take 5–10 minutes to acquire a satellite fix. Subsequent warm starts drop back under a minute once the almanac data is rebuilt.
Why the RoadMate 2230 shuts off without a low-battery warning
The RoadMate 2230 reads remaining charge by measuring cell voltage. After years of cycling, the original cell's voltage curve flattens — the unit reports adequate charge right up until voltage collapses past the cutoff threshold. The on-screen battery indicator never catches up, so the device just switches off. A fresh cell restores a predictable voltage curve, and the indicator behaves as expected again.
GPS accuracy drops during active navigation at low battery
At low cell voltage, the RoadMate reduces power to the GPS receiver module to protect the remaining charge. Lower receiver power means weaker satellite signal processing, which degrades position accuracy — you may notice the cursor drifting or lag in turn-by-turn updates. This is not a software fault. Keep the cell above 3.6V during active use to maintain full receiver sensitivity. Charging via the vehicle adapter while navigating is the most direct fix.

Frequently Asked Questions
My RoadMate 2230 lost all my saved routes after I swapped the battery — is that normal?
Yes. The RoadMate 2230 stores some route and POI data in RAM that relies on continuous power to retain its contents. A full battery removal wipes that power entirely, clearing anything held in volatile memory. Favourites and custom POIs stored to internal flash are usually unaffected, but active routes and recent destinations are typically lost. Re-enter your destinations after the swap and save them to the device's favourites to protect them going forward.
After fitting this battery, the RoadMate 2230 takes forever to find satellites — what's happening?
This is a cold start, and it's expected after any full power loss. The GPS receiver discards its cached almanac data — the stored map of satellite positions — when power is cut completely. Without that data, the unit has to download a fresh almanac from scratch, which takes 5–10 minutes outdoors with a clear sky view. Park the vehicle outside, leave it stationary, and let the unit run until the satellite bar fills. Subsequent startups will lock in under a minute.
The RoadMate 2230 battery drains much faster when I'm actively navigating than when the screen is off — is something wrong with this cell?
Nothing is wrong. Active navigation runs both the GPS receiver and the display simultaneously — those two components draw significantly more current than standby. Screen brightness is the biggest variable; dropping it one or two steps reduces display draw noticeably. If drain is still faster than expected, check that the screen timeout is set to dim during stationary stops. Plugging into the vehicle's 12V adapter during long routes keeps the cell topped above 3.6V and avoids any receiver power-throttling at low voltage.
