Verizon Jetpack replacement battery

This Cameron & Co DS-CS-PTR900SL lithium-ion cell is built for the Verizon Ellipsis Jetpack and Franklin Wireless MHS900L hotspot models. It replaces the original FWCR900BATS and V604454AR packs with a 3.8 V, 2.1 Ah rating. The black housing matches the OEM dimensions of 55.95 x 43.90 x 6.40 mm. Owners of those specific hotspots can restore factory runtime with a direct-fit unit.

Upgrade from a depleted original pack

The swap makes sense when the stock cell no longer holds a full day of tethering or shows swelling. A fresh 2100 mAh unit restores the 7.98 Wh capacity the device was designed around. Users who only need occasional backup power may not notice the difference. Heavy hotspot users who rely on continuous LTE connectivity will see the runtime return to new-device levels.

Straightforward user installation

The battery sits behind a removable cover and connects with the original plug — no soldering or tools required. Align the connector carefully; forcing it can bend the fragile header pins on the hotspot board. The thin 6.40 mm profile leaves little margin, so press evenly across the cell surface. Dispose of the old pack at a proper recycling point.

Questions about this item

Will the 55.95 mm by 43.90 mm by 6.40 mm DS-CS-PTR900SL fit inside my Verizon Ellipsis Jetpack?

Yes — those dimensions match the original FWCR900BATS pack used in the Franklin Wireless MHS900L and XHG-R300, so the battery slides into the same compartment without modification.

What is the correct way to insert the 3.8 V 2.1 Ah Li-ion cell, and what step do people often miss?

Align the gold contacts with the Jetpack's connector, press firmly until the latch clicks, then power the device on to let the fuel gauge calibrate — skipping that first charge cycle is the common mistake.

When will the 2100 mAh pack need replacing under normal daily use?

Typical Li-ion cells of this capacity deliver several hundred full cycles; when run-time falls to roughly half of the original 7.98 Wh rating, it is time for a new DS-CS-PTR900SL.
