Questions about this item

How long will the 850 mAh capacity actually run my Rexton WL200AP remote?

The 850 mAh pack delivers 3.15 Wh at 3.7 V, which typically powers the WL200AP remote through a full day of normal hearing-aid adjustments before needing a recharge.

What connector standard does this Li-ion pack use to attach to the device?

It uses the original Siemens Rexton WL200AP battery interface, matching part number 21221-10296051, so it clicks straight into the remote without adapters.

Will the 51.38 x 34.00 x 5.70 mm dimensions fit inside the BLU RCU battery compartment?

Yes, those exact millimetre measurements match the OEM cavity, so the black Li-ion cell sits flush and the cover closes normally.
