Garmin Nuvi 2200 361-00050-02 Replacement Battery 3.7V 800mAh

Garmin Nuvi 2200 Series — 3.7V Li-ion Replacement Battery (361-00050-02)

This is a 3.7V, 800mAh Li-ion replacement cell for the Garmin Nuvi 2200, 2200LT, 2240, and 2250 portable GPS navigators. It replaces OEM part numbers 361-00050-02, 361-00050-01, and 361-00050-04. The cell fits the same physical bay and connects to the same charging circuit as the original.

• Nuvi 2200 series compatibility: The 2200, 2200LT, 2240, and 2250 share the same battery bay dimensions, connector pinout, and 3.7V charging rail. One cell fits all four models without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Nuvi 2250. The BMS accepted the charge handshake on first connection and held the voltage curve within spec across full cycles.
• First-use satellite acquisition: After fitting this cell, power the unit on outdoors and let it acquire a full satellite fix before driving. The GPS runs a cold start after any full power interruption — first fix takes 5 to 10 minutes. Subsequent warm starts drop back under a minute once the almanac is cached.

GPS accuracy reduced at low battery on the Nuvi 2200

When the Nuvi 2200 drops below a certain voltage threshold, the receiver reduces sensitivity to conserve power. This shows up as position drift or a wider accuracy circle on the map even in open-sky conditions. It is not a GPS signal problem — it is a power management response. Replacing a degraded cell that can no longer hold voltage under load restores full receiver sensitivity.

Nuvi 2200 shuts off without warning instead of showing a low battery alert

A battery that has aged past its usable capacity loses voltage quickly under the load of the display and GPS receiver running together. The on-screen battery indicator reads the resting voltage, not the loaded voltage — so the indicator still shows one bar when the cell is already sagging below the cutoff threshold under load. The unit shuts off mid-route with no warning because the BMS trips on the loaded voltage drop, not the displayed estimate. After fitting a new cell, recalibrate the indicator by running two full charge-to-discharge cycles before trusting the on-screen percentage.
