Replacement Battery for EnGenius Handsets

Users Needing Longer Runtime on Supported Models

The higher capacity suits professionals who rely on their EnGenius handsets throughout long shifts and want fewer recharge cycles. Buyers with other phone brands or proprietary battery form factors cannot use this pack and should look for a model matched to their specific device.

Sustained Talk Time and Shelf Life
