Replacement battery for Novatel MiFi hotspots

This Estry battery replaces the original pack in Novatel Wireless MiFi 3352, 4510L, 4082 and related 4G mobile hotspots. It is a single lithium cell rated at 3.7 V and 1400 mAh, built to the same physical and electrical specifications as the factory unit. The pack includes overcharge, over-discharge, over-voltage and short-circuit protection for safer operation. Buyers who need a higher-capacity cell or a different form factor should look elsewhere.

Lithium-ion chemistry limits for mobile router use

Lithium-ion cells of this capacity typically deliver several hours of continuous hotspot operation before requiring a recharge. Runtime varies with signal strength, number of connected devices and data throughput, so heavy users may see shorter intervals between charges. The battery operates within the standard 3.7 V nominal range and cannot be fast-charged beyond the router's built-in controller limits. Users who need all-day uptime without access to mains power will find a single pack insufficient.

1400 mAh capacity at 3.7 V decides fit

The 1400 mAh rating at 3.7 V matches the original 40115118.001, 40115118.002, 40115118.003 and 40123111.00 part numbers listed for the compatible MiFi models. Physical dimensions of 65.8 x 43.6 x 5.0 mm and a weight of 54.0 g ensure the pack seats correctly in the device's battery compartment. Verify your hotspot model and part number against the compatibility list before ordering.

Questions about this item

Should I pick the 1400mAh or the 1350mAh version?

The label states 1400mAh; the detailed spec lists 1350mAh at 3.7V (5.0Wh). Both refer to the same physical cell — choose this one pack.

What runtime does 1400mAh at 3.7V give in a MiFi 3352 hotspot?

At 3.7V the cell stores 5.0Wh. Typical MiFi draw is 1–2W, so expect roughly 2.5–5 hours of active use before recharge.

Does the battery connector match the Novatel 40115118.003 part number?

Yes — this replacement is built to the original 40115118.003 spec and fits MiFi 3352, 4510, 4082 and listed models.
