Voice Caddie VC200 Voice GPS Replacement Battery 3.7V 270mAh

Voice Caddie VC200 / VC200 Voice — 3.7V Li-Polymer Replacement Battery (GN452528)

This is a 3.7V 270mAh Li-Polymer cell for the Voice Caddie VC200 and VC200 Voice handheld golf GPS devices. It replaces OEM part GN452528 and restores power to the navigator's course data, distance readouts, and shot-tracking functions. Dimensions are 29.00 x 23.30 x 4.60mm — verify these against your existing cell before fitting.

• VC200 and VC200 Voice compatibility: Both devices share the same battery bay dimensions, connector pinout, and BMS handshake protocol. The GN452528 part number covers the full VC200 range — no hardware difference between the voice and non-voice variants that affects battery fitment.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the VC200 platform. The BMS accepted the cell without fault codes, voltage sat steady at 3.7V nominal, and the protection circuit tripped correctly at both over-voltage and low-voltage thresholds.
• Cold-start after power interruption: After fitting this cell, power the device on outdoors and let it acquire a satellite fix before use. Full power removal resets the GPS to a cold start — first lock can take 5–10 minutes. Subsequent warm starts drop to under a minute once almanac data is cached.

GPS accuracy dropping at low battery on the VC200

As the GN452528 cell ages and capacity fades, the VC200 receiver begins reducing sensitivity to conserve the remaining voltage. At low charge, the GPS chip draws less power to the antenna circuit, which narrows the number of satellites tracked. Fewer satellites means wider positional error — distances to the pin can read 5–15 yards off. Replacing the cell restores full receiver power and returns accuracy to spec.

VC200 shutting off without a low-battery warning

The VC200's fuel gauge is calibrated against the original cell's discharge curve. An aged or mismatched cell collapses voltage faster than the gauge anticipates, so the device hits the 3.0V hardware cutoff before the on-screen indicator reaches the warning threshold. The unit simply powers off mid-round with no visual alert. After fitting a fresh GN452528 cell, run two full charge-discharge cycles so the fuel gauge can re-calibrate its low-voltage warning against the new cell's actual curve.
