Battery for Sprint Sierra Wireless 803S

This 3600mAh lithium-ion cell replaces the original W-4 pack in the Sprint Sierra Wireless 803S 4G LTE, Aircard 803S and SWAC803SMH. It is built for users who need a fresh power source for daily mobile broadband use. The CE-certified unit has no memory effect and includes overcharge protection with an onboard microchip.

Overcharge protection and microchip

Built-in overcharge protection and a battery-life microchip guard the cell during charge cycles, reducing the risk of swelling or premature capacity loss. No memory effect means the battery can be topped up at any state of charge without degrading its 3600mAh rating. The CE mark confirms compliance with European safety requirements.

Direct replacement, simple swap

The pack matches the original 69.60 x 49.55 x 14.50mm footprint and connects to the same terminals, so installation is a straight battery-door swap with no tools or firmware steps. Buyers whose device uses a different Sierra Wireless model or a non-W-4 part number will find this pack incompatible.

Questions about this item

How often will the SCS-SPT803RX battery need to be replaced under normal use?

The 3600mAh lithium-ion cell has no memory effect and includes overcharge protection with a built-in microchip, so it only requires replacement when its runtime noticeably drops after many charge cycles.

What limits the runtime of the SCS-SPT803RX during continuous 4G LTE operation?

The 3600mAh capacity sets the energy budget; sustained high-speed data use on the Sprint Sierra Wireless 803S will drain the pack faster than standby, making capacity the first limit reached.

Does the SCS-SPT803RX get hot or draw extra power when the hotspot runs all day?

The battery itself has no active cooling or fan; it simply stores 3600mAh and relies on the Aircard 803S to manage its own thermal and power behaviour during extended use.
