About this replacement
Garmin Edge 130 Series — 3.7V Li-Polymer Replacement Battery (361-00086-02)
This is a 3.7V 150mAh (0.56Wh) Li-Polymer cell for the Garmin Edge 130 and Edge 130 Plus GPS cycling computers. It fits OEM part number 361-00086-02 and matches the original cell dimensions at 29.70 × 19.25 × 3.34mm. Swap it when your Edge 130 no longer holds charge or shuts off unexpectedly mid-ride.
- Edge 130 and Edge 130 Plus compatibility: Both models share the same cell format, connector orientation, and BMS voltage thresholds. The 361-00086-02 part number covers the full range, so one cell fits either unit without modification.
- Bench tested on actual hardware: We cycled this cell through charge and discharge on the Edge 130 platform. The BMS accepted the cell without error flags, held charge to the correct cutoff voltage, and triggered low-battery alerts at the expected threshold.
- First cold-start after swap: After fitting this cell, power the device on outdoors and let it acquire a satellite fix before heading out. A full power interruption forces a cold start — first GPS lock can take 5–10 minutes versus under a minute once almanac data is cached.
Edge 130 shutting off without a low-battery warning
After prolonged use, the Edge 130's battery indicator can lose calibration against the actual cell's discharge curve. The device hits the low-voltage cutoff internally before the on-screen percentage has dropped far enough to display a warning. This is a fuel-gauge drift issue, not a fault with the replacement cell. Run two full charge-to-cutoff cycles after fitting the new battery — this lets the BMS recalibrate its state-of-charge estimate against the new cell's actual capacity curve.
Saved routes missing after battery replacement
The Edge 130 stores course and route data in flash memory, but activity data in progress and some navigation state can sit in volatile RAM that clears on full power removal. If you swap the cell mid-sync or without a prior full sync to Garmin Connect, that unsaved data is gone. Before pulling the old cell, complete a sync via Bluetooth or USB so all ride data is offloaded. After fitting the new cell, re-import any courses from Garmin Connect to the device before your next ride.
