Questions about this item

Will the 114.20 x 60.00 x 23.40 mm dimensions fit my Avaya TransTalk 9040 handset?

Yes, the battery is built to the exact specifications of the original Avaya 320409B pack, so the 114.20 x 60.00 x 23.40 mm footprint matches the TransTalk 9040 battery compartment precisely.

What is the installation step people often miss when fitting this 3.85 V replacement?

After placing the cell, you must press the connector firmly until it clicks; a loose plug will leave the TransTalk 9631 dead even though the battery is good.

How many charge cycles before the 2000mAh capacity stabilises?

The manufacturer states the cell reaches its best performance after 2 or 3 full charge and discharge cycles.
