Questions about this item

Does my device need a BP1736 battery slot for this 1800mAh 3.8V pack to fit?

Yes, this replacement matches the BP1736 part number and the 68.1 x 58.0 x 4.5mm dimensions of the original Kazuna battery.

Will the 6.84Wh capacity work with the original charger in my KAZN20PP handset?

The 1800mAh 3.8V rating is identical to the factory cell, so the stock charger will charge it normally.

How can I confirm the 3.8V 1800mAh cell is operating correctly after installation?

The phone should power on, show a full charge cycle, and run for the same talk and standby time as the original battery.
