Questions about this item

My cordless phone uses the original 288645 pack — will this 3.6 V 700 mAh Ni-MH battery fit the same compartment?

Yes, it matches the 288645 part number and the 45.6 × 31.3 × 10.6 mm dimensions, so it slides into the same battery bay.

I still have a handset that takes the BT188645 cell — does this replacement charge on the original base station?

The pack shares the 3.6 V rating and 700 mAh capacity of the BT188645, so the existing charger will replenish it normally.

After installing the battery, how can I confirm it is delivering the rated 2.52 Wh?

A full charge followed by a talk-time test of several hours shows the 700 mAh capacity is being met.
