Cameron Sino 1700mAh 6.29Wh Battery HB554666RAW HB5F2H

Cameron Sino 1700mAh Replacement Battery

This Cameron Sino lithium-ion cell delivers 1700mAh at 3.7V for compatible Huawei mobile hotspots. It replaces the original HB554666RAW and HB5F2H packs in models such as the E5330, E5336, E5372, E5373, E5375, E5377 and E5377S-32. The new, fully decoded chip communicates with the device exactly as the factory battery did. Installers should verify the part number on their existing pack before purchase.

Practical Limits of the 3.7V Single-Cell Design

A single 3.7V cell cannot supply higher voltages without a boost circuit, so runtime scales directly with the 6.29Wh rating. The protection board prevents over-charge, over-discharge, over-voltage and short-circuit events, but it does not increase the fundamental energy capacity. Users relying on continuous maximum-throughput tethering will see the pack deplete faster than the rated milliampere-hours suggest.

1700mAh Capacity and Thermal Headroom

The 6.29Wh pack comfortably powers typical hotspot workloads for several hours per charge. Extended 4G or heavy multi-client use will exhaust the reserve more quickly, and the cell must not be stored above 60°C or 140°F. The 30.9g unit fits the 65.10 x 45.70 x 5.30mm cavity without modification, but it cannot support devices that demand a larger pack or higher watt-hour rating.
