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.

How can I confirm the 3.7 V 5040 mAh battery is working correctly after installing it in my Telstra MR2100 NightHawk M2 hotspot?

Insert the battery, power on the hotspot and verify the on-screen battery indicator shows a charge level; the device should maintain a 4G connection and provide Wi-Fi for the expected runtime of an 18.65 Wh cell.

The package contains one 3.7 V 5040 mAh Li-Polymer battery measuring 78.70 x 62.40 x 9.32 mm; no cables, chargers or tools are included, and the hotspot’s existing charger is used for recharging.

Which capacity version of the DS-CS-TRA110SL should I choose for the Telstra MR2100 NightHawk M2 W-10a?

Only the 5.04 Ah (5040 mAh / 18.65 Wh) black Li-Polymer version is listed, and it directly replaces the W-10a cell in the MR2100 and NightHawk M2 hotspots.
