Nortek 208882 Battery 3V Lithium 2450

Overview

The Nortek 208882 is a 3V lithium battery (2450 cell type) designed as a replacement power source for Nortek access control systems and related security devices. This battery supports backup or primary power for wireless door locks, readers, and control panels that require extended shelf life and stable voltage delivery. The 3V lithium format provides approximately 600–800 mAh capacity depending on load profile, making it suitable for low-draw wireless and intermittent-duty applications where alkaline or rechargeable alternatives fall short on cycle life or self-discharge rates.

Compatibility

The Nortek 208882 fits Nortek-branded access control equipment and third-party devices that specify a 2450 lithium cell replacement. Confirm your specific system model against the Nortek documentation or parts list before ordering—lithium cell compatibility is not backward-compatible with other battery chemistries or sizes. If your hardware draws continuous current above 50 mA, verify runtime calculations with the device manufacturer, as lithium coin cells exhibit voltage sag under sustained high load.

Installation Notes

Lithium cells are non-rechargeable and should be installed with the positive (+) terminal facing outward unless the device holder is marked otherwise. Avoid touching the cell terminals with bare hands to prevent contamination and premature discharge. Do not attempt to recharge this battery—lithium cells are not designed for recharging and pose a fire risk if forced. Store in a cool, dry location away from metal objects to prevent short-circuit. Check the expiration or manufacture date before deployment; shelf life is typically 5–10 years from manufacture under normal storage conditions.
