Questions about this item

How do I install the WX-SB100 battery in my Attune II device?

Power off the device, open the battery compartment, align the 3.7 V pack with the polarity markings, press until it clicks, then close the cover and power on.

What replacement will the WX-SB100 need over time?

The 700 mAh lithium cell will gradually lose capacity; after several hundred charge cycles it should be swapped for a new WX-SB100 pack.

What limit appears first during continuous use of the 700 mAh pack?

The 2.59 Wh capacity determines runtime; sustained load will drain the cell until the built-in protection cuts power to prevent over-discharge.
