This Cameron & Co battery replaces the AT&T 5200080 W-6 pack used in the Netgear Aircard 781S Unite Pro 4G LTE hotspot. It is a lithium-ion cell rated at 3.7V and 2.2 Ah, matching the original 2200mAh capacity. The pack fits the 77.30 x 55.00 x 9.60 mm footprint of the factory battery.
Low self-discharge lithium-ion chemistry
Lithium-ion construction keeps self-discharge minimal while the hotspot sits idle between trips. The 8.14 Wh energy rating supports typical mobile-router workloads without generating noticeable heat. Normal charging and discharging cycles stay within the thermal limits of the original design.
Ready to install with no extra parts
The black housing snaps into the Aircard 781S battery compartment using the existing latch mechanism. No tools, adapters or firmware updates are required to recognise the cell. The package contains one 100% OEM-compatible battery for immediate deployment.

Questions about this item
How do I install the DS-CS-ATP781RC in my Netgear Aircard 781S, and what step is often missed?
Power off the hotspot, remove the back cover, insert the 77.30 x 55.00 x 9.60 mm pack with contacts aligned, then replace the cover before turning it on — skipping the power-off step can prevent the device from recognising the new 3.7 V cell.
What replacement will this 2.2 Ah Li-ion pack need over time?
The battery itself is the only replaceable part; once its 2200 mAh capacity degrades below usable runtime, you swap in another DS-CS-ATP781RC.
What limit appears first during continuous 4G LTE use on the Aircard 781S?
The 8.14 Wh capacity typically runs out before thermal limits, giving several hours of hotspot operation per full charge.
