Replacement battery for Franklin Wireless hotspots

The Cameron & Co DS-CS-FWR850SL is a lithium-ion cell built for Franklin Wireless R717, R850, T9 and T-Mobile DP15 mobile hotspots. It replaces the original DP15 pack and restores factory runtime for users who rely on portable 4G connectivity. The 2.45 Ah capacity matches the OEM specification for these devices.

Single-cell lithium-ion limits

The pack uses a single 3.8 V lithium-ion cell rated at 9.31 Wh, so total energy is fixed by chemistry and volume. It cannot be paralleled or series-connected inside the hotspot, and the 5.74 mm thickness leaves no room for a higher-capacity cell. Runtime scales linearly with the hotspot's modem load and signal conditions.

Upgrade from depleted or ageing original packs

This battery replaces an exhausted OEM cell that no longer holds a full charge or that shuts down under load. The jump is worth it when the hotspot cannot complete a work shift or travel day on one charge. It is not for users who need more capacity than the factory form factor allows.

Questions about this item

Should I pick the 2.45 Ah version for my Franklin Wireless R850?

Yes — this 2.45 Ah / 9.31 Wh cell is the exact capacity specified for the R850, R717, T9 and T-Mobile DP15 hotspots.

How long will the 9.31 Wh rating last in daily hotspot use?

The 3.8 V 2450 mAh cell delivers 9.31 Wh, which typically powers a Franklin Wireless hotspot for a full work day of moderate tethering.

Does the 3.8 V Li-ion chemistry limit charging speed on the T-Mobile DP15?

The pack uses standard 3.8 V Li-ion chemistry and charges at the rate the DP15's built-in controller allows — no faster, no slower.
