Replacement Battery for Frontier NVG589 Modems

This lithium-ion pack replaces the original battery in Frontier NVG589 cable modems. It delivers 5600mAh at 7.4 volts for 41.44Wh of backup capacity. A decoded chip ensures the modem recognises the pack exactly like the factory unit.

Backup Power Limits for Cable Modem Use

The pack supplies reserve power only when the mains supply fails, so internet and voice service stay up during short outages. Runtime depends entirely on the modem's own draw, which the battery cannot change. It is not a portable power bank and cannot run other devices.

Compact Pack with Integrated Protection Circuitry

The cell measures 83.30 by 79.20 by 21.40 millimetres and weighs 225.0 grams, fitting the modem's existing battery bay without modification. Built-in safeguards guard against overcharge, over-discharge, over-voltage and short circuits. Foam packaging protects the unit during transit.

Questions about this item

Should I choose the 5600mAh version or the 400mAh version for my FRONTIER NVG589?

The 5600mAh / 41.44Wh figure is the full battery-pack rating at 7.4V that replaces the original FRONTIER NVG589 unit. The 400mAh / 3.70V value refers to the individual cell inside; select the 5600mAh pack for a direct replacement.

What does the 5600mAh capacity actually deliver once installed in the NVG589?

At the pack voltage of 7.4V the 5600mAh rating provides 41.44Wh of energy, giving the cable modem backup runtime equivalent to the original factory battery under the same load conditions.

Does the battery use a standard connector or a proprietary interface, and does that limit compatibility?

The replacement includes a fully decoded chip and connector that match the original FRONTIER NVG589 interface, so it communicates correctly with the modem’s charging and monitoring circuitry without adapters.
