Blaupunkt TravelPilot 500 Compatible Battery 3.7V 2200mAh

Blaupunkt TravelPilot 500 / 700 — 3.7V Li-ion Replacement Battery (523450L110)

This 3.7V 2200mAh Li-ion cell replaces the original battery in the Blaupunkt TravelPilot 500 and TravelPilot 700 portable GPS navigators. It matches the OEM dimensions at 52.78 × 34.23 × 10.95mm and uses OEM part references 523450L110 and 1S2PMX. Capacity is rated at 8.14Wh — identical to the factory spec.

• TravelPilot 500 and 700 fitment: Both units share the same battery bay dimensions, connector orientation, and single-cell 3.7V architecture. The BMS handshake is identical across both models, so one cell covers either unit without modification.
• Bench tested on actual hardware: We ran this cell through charge and discharge cycles on a TravelPilot unit. The BMS accepted the cell without fault flags, balanced correctly at full charge, and held voltage within the expected window across a standard navigation session.
• First fix after installation: After fitting this cell, power the GPS fully on outdoors before use. The unit performs a cold start after any full power interruption — first satellite acquisition can take 5–10 minutes. Subsequent warm starts drop to under a minute once the almanac is cached.

GPS battery draining faster during active navigation than standby

The TravelPilot draws significantly more current during active routing than when idle. The GPS receiver runs continuously, the processor recalculates turn-by-turn data, and the display stays at full brightness — all three loads run simultaneously. On a fresh cell this is normal behaviour, not a fault. Reducing display brightness is the single most effective way to lower draw during long drives.

TravelPilot 500 shutting off without warning at low battery

This happens when the battery indicator loses calibration after a cell swap. The fuel gauge reads remaining charge as a percentage based on learned discharge curves from the old cell — after replacement, those curves no longer match. The device hits the BMS low-voltage cutoff before the on-screen warning triggers. Run two full charge-to-discharge cycles to let the gauge recalibrate against the new cell; the warning should align to cutoff at or above 3.4V after that.
