Sureshotgps Micro V3 Replacement Battery H603450H 3.7V 1100mAh

Sureshotgps Micro V3 / C2796 — 3.7V Li-ion Replacement Battery (H603450H)

This 3.7V 1100mAh Li-ion cell replaces the original H603450H battery in the Sureshotgps Micro V3 and C2796 portable GPS navigators. It restores power to devices used for outdoor tracking, route navigation, and location logging. Capacity matches the product data at 4.07Wh — no upsizing, no guesswork.

• Micro V3 and C2796 compatibility: Both models share the same battery bay dimensions, connector pinout, and 3.7V nominal rail. The H603450H part number covers both. No adapter or modification needed.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a GPS test rig. The BMS responded correctly to full charge termination and low-voltage cutoff — no false flags, no premature shutdown during active navigation mode.
• Cold start after battery swap: After fitting this cell, power the unit on outdoors and let it acquire a satellite fix before use. GPS devices perform a cold start after full power removal — first fix can take 5–10 minutes. Subsequent warm starts drop under a minute once almanac data is re-cached.

GPS battery draining faster during active navigation than standby

The Micro V3 draws significantly more current when actively navigating versus sitting idle. The GPS receiver, display backlight, and route calculation all pull current simultaneously in navigation mode. Standby keeps the receiver in a low-power state and dims or cuts the display. If drain seems excessive, reduce backlight brightness — it is often the largest single draw in this device class.

Device shuts off without warning before the low-battery indicator appears

This happens when the fuel gauge or voltage-threshold indicator loses calibration — common after a full battery swap. The unit's shutdown voltage threshold gets hit before the visual warning triggers. To recalibrate, run the battery down until the device shuts off naturally, then charge fully to 4.2V in one uninterrupted session. Repeat once — the threshold mapping resets after a full discharge-charge cycle.
