Signs You May Need a New Franklin T9 or R850 Battery

Rechargeable hotspot batteries gradually lose capacity with age and repeated charging. Your Franklin DP15 battery may need replacement if you notice one or more of these symptoms:

• The hotspot runs for much less time than it did when new.
• The T9 or R850 turns off shortly after being unplugged.
• The hotspot restarts when multiple devices connect.
• The battery percentage drops suddenly or changes unpredictably.
• The device only operates reliably while attached to a charger.
• The hotspot shuts down while downloading, streaming or transferring data.
• The battery becomes unusually warm during ordinary use.
• The rear battery cover no longer sits flat because the battery is swollen.
• The battery appears to charge fully but loses power within a short time.

Stop using the battery immediately if it is swollen, leaking, punctured or excessively hot. Do not press down on a swollen battery or force the hotspot's rear cover closed.

Frequently Asked Questions

Q: Is this an original OEM Franklin DP15 battery?
A: Yes. This is a new original OEM Franklin Wireless DP15 rechargeable battery. It is not a generic aftermarket replacement battery.

Q: Which hotspots use the Franklin DP15 2450mAh battery?
A: The DP15 battery is commonly used in the T-Mobile Franklin T9 and compatible Franklin Wireless hotspot models including the R850, R717 and R871. Always compare the model number and specifications printed on your original battery before ordering.

Q: Is the Franklin T9 battery removable?
A: Yes. The T9 uses a removable rechargeable battery located behind the hotspot's rear cover. Turn the device off and disconnect the charger before removing the battery.

Q: What are the specifications of the Franklin T9 and R850 battery?
A: This DP15 lithium-ion battery is rated at 3.8V, 2450mAh and 9.31Wh.

Q: Can a worn battery make my Franklin hotspot restart?
A: Yes. A worn battery may not provide stable power when the hotspot is transmitting data or supporting several connected devices. This can cause unexpected shutdowns, restarts or interrupted connections.

Q: Will a new battery improve the hotspot's cellular signal?
A: A new battery does not directly increase cellular signal strength or network speed. However, replacing an unstable battery may prevent power-related shutdowns and restarts that interrupt your internet connection.

Q: Can I use the Franklin T9 while the battery is charging?
A: The T9 can normally operate while connected to an appropriate power source. Charging may take longer when the hotspot is actively providing Wi-Fi service, especially when several devices are connected.

Q: Should I leave my Franklin hotspot plugged in all the time?
A: Long periods of continuous charging and excess heat can shorten the useful life of a lithium-ion battery. When practical, keep the hotspot in a ventilated location and avoid covering it while it is charging or transmitting data.

Q: Should I fully charge the new DP15 battery before using it?
A: Install the battery and charge it fully with the appropriate charger before depending on it for extended portable use. The battery indicator may become more accurate after several normal charge and discharge cycles.

Q: What should I do if my old Franklin battery is swollen?
A: Turn the hotspot off, unplug it and stop using the battery immediately. Do not puncture, bend or press on a swollen lithium-ion battery. Take it to an authorized battery-recycling or household hazardous-waste facility.

A: Yes. Your purchase is protected by our No Hassle One Year Warranty.
