Rikaline GPS-6033 Replacement Battery 3.7V 1000mAh Li-ion

Rikaline GPS-6033 / 6030 — 3.7V Li-ion Replacement Battery (300-203712001)

This is a 3.7V, 1000mAh Li-ion cell built to replace the original battery in the Rikaline GPS-6033 and GPS-6030 handheld GPS navigators. It matches the OEM part number 300-203712001 and fits the same physical bay. Dimensions are 57.50 × 35.51 × 7.45mm — measure your current cell before ordering if you are unsure.

• GPS-6033 and GPS-6030 compatibility: Both models share the same battery bay dimensions, connector pin-out, and 3.7V power rail, so one cell covers either unit without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on GPS navigator hardware, confirmed the protection circuit trips at the correct low-voltage cutoff, and verified the connector seated flush with no voltage drop at the terminal.
• Cold-start procedure after fitting: After installing this cell, take the GPS-6033 outdoors and power it on before your first use. The unit performs a full cold start after any complete power interruption — first satellite acquisition can take 5–10 minutes in open sky. Subsequent warm starts are under a minute once the almanac is cached.

GPS-6033 shutting off without warning at low battery

After extended use, the GPS-6033's battery indicator can read one bar and then cut power with no further warning. This happens because the on-screen indicator is calibrated to the discharge curve of the original cell — a replacement cell with a slightly different curve hits the device's voltage cutoff threshold before the indicator reaches empty. The fix is to run the battery through two or three full charge-discharge cycles so the device re-maps the indicator to the new cell's curve. Once calibrated, low-battery warnings appear at around 3.5V as expected.

Saved routes and POIs missing after battery swap

Some route data and points of interest on the GPS-6033 are held in battery-backed RAM rather than flash storage. A full power removal — as happens during a battery swap — clears that volatile memory. Before pulling the old battery, export any saved routes to your PC via the Rikaline software utility. After fitting this cell and powering back on, re-import the exported data to restore your waypoints.
