Direct replacement for IFWA-40 hotspot

This lithium-ion battery matches the original BAT-40 part with a capacity of 3000mAh and 11.10Wh at 3.70 volts. It fits the AT&T IFWA-40 Wireless Internet Wi-Fi Hotspot Router and Home Phone Base 4G LTE. A fully decoded chip ensures the device recognises the pack exactly like the factory unit. Buyers who need a different voltage or form factor cannot use this pack.

Low self-discharge chemistry and protection circuits

The cell uses standard lithium-ion chemistry rated at 3.70 volts with built-in overcharge, over-discharge, over-voltage and short-circuit protection. In normal hotspot operation the pack runs cool and silent because it has no moving parts. The supplier notes that performance stabilises after two or three full charge and discharge cycles. Users who require active cooling or a fan-assisted design will not find it here.

Steady output during extended hotspot sessions

Under continuous 4G LTE data use the battery maintains a stable 3.70 volt rail thanks to its protection circuitry and 3000mAh capacity. The 62.0g pack is housed in shock-absorbing foam for transport safety and measures 65.00 x 44.30 x 10.20mm. Long-term storage above 60 Celsius is discouraged by the manufacturer. Installations needing a higher sustained current or larger capacity must choose another solution.

Questions about this item

How do I install the BAT-40 battery in my IFWA-40 hotspot, and what step do people often get wrong?

Open the battery compartment, align the connector, and press it in until it clicks; the step most people miss is fully seating the connector so the decoded chip communicates with the router.

What maintenance or replacement will this 3000mAh lithium-ion pack need later?

After 2 or 3 full charge and discharge cycles the pack reaches its best capacity; replace it when run-time drops below your needs or if the pack swells or overheats.

What limit appears first when the IFWA-40 runs continuously on this 11.10Wh battery?

The 3000mAh capacity sets the runtime ceiling; sustained 4G LTE use will drain the pack until the protection circuit cuts power at the low-voltage threshold.
