Compatible Telstra Hotspot Battery

The Cameron & Co DS-CS-TRA110SL is a new lithium-polymer cell rated at 3.7 V and 5040 mAh, giving 18.65 Wh of energy. It matches the original W-10a part for the Telstra MR2100 NightHawk M2 hotspot. The black pack measures 78.70 x 62.40 x 9.32 mm and is sold as a single unit.

Who Should Buy This

Owners of a Telstra MR2100 or NightHawk M2 mobile hotspot who need a direct replacement for a worn or damaged W-10a battery will find this part fits and connects correctly. It is not for users of other hotspot models, devices that require a different voltage, or anyone needing a higher-capacity pack.

Deciding Specification

The critical figure is the 3.7 V 5040 mAh rating, which equals 18.65 Wh. If your device specifies that exact voltage and capacity, this battery is the correct match; if the label shows a different voltage or watt-hour value, this unit will not work.
