Replacement Battery for TP-Link Hotspots

This Cameron & Co DS-CS-TTR961SL is a 3.8V 1900mAh lithium-ion cell built for the TP-Link M7350, M7350 Ver 2 and TL-TR961 mobile hotspots. It restores factory run-time when the original pack no longer holds a charge. Buyers needing power for other router models or larger capacity packs will not be served by this specific part.

Direct Swap for TBL-55A2550

The cell replaces the OEM TBL-55A2550 battery on a one-to-one basis, matching the 7.22Wh rating and 68.48 x 48.55 x 5.60 mm footprint. The upgrade is worth it when the hotspot shuts down early or refuses to power on away from the charger. If the device itself is faulty, a fresh battery will not solve the problem.

Simple User Installation

The pack slides into the hotspot's battery compartment without tools; the connector is keyed to prevent reverse insertion. Common issues are forgetting to remove the plastic insulating tab on new cells or not seating the pack fully before closing the cover. Always charge fully before first use to calibrate the fuel gauge.

Questions about this item

What are the exact dimensions of the DS-CS-TTR961SL battery for the TP-Link M7350?

The battery measures 68.48 mm by 48.55 mm by 5.60 mm, matching the original TBL-55A2550 form factor for the TP-Link M7350 and M7350 Ver 2 hotspot models.

How do I correctly install this replacement battery in my TP-Link M7350 hotspot?

Power off the device, remove the rear cover, disconnect the old battery connector, connect the new DS-CS-TTR961SL connector firmly, and replace the cover; the step often missed is ensuring the connector clicks fully into the socket.

When should I expect to replace the DS-CS-TTR961SL battery in my TP-Link hotspot?

Replace the 3.8 V 1900 mAh Li-ion cell when runtime drops noticeably below the original 7.22 Wh capacity or the hotspot shuts down unexpectedly under load.
