Questions about this item
How do I install the Cameron Sino battery into my Avaya 20DT handset, and what step is often missed?
Power off the handset, remove the battery cover, disconnect the old pack, connect the new 4750mAh battery ensuring the plug clicks fully into the socket, refit the cover, then place the handset on its charger for a full initial charge cycle.
What maintenance will the 36.58Wh pack need over its service life?
No scheduled maintenance is required; when talk time drops noticeably below the rated 4750mAh capacity, replace the pack with a new Cameron Sino unit of the same specification.
What limit appears first during a long shift of continuous calls on the WT9620?
The 4750mAh capacity determines runtime; after roughly the rated talk time the handset will signal low battery and require recharging on its base station.
