Direct Replacement for Aiwa Cordless Phones

The Estry HS-PX787 is a 1.2V 1200mAh Ni-MH battery built to match the original specifications for a long list of Aiwa handsets. It fits models including the AM-HX50, AM-HX300, AM-HX200, AM-HX70, AM-HX100, AM-HX150 and AM-HX400 as well as the HS-PX587 and HS-PX787 packs. Overcharge, over-discharge, over-voltage and short-circuit protection are integrated for safer daily use. Certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Upgrade from Worn Original Packs

This cell replaces the factory MHB-901 pack when talk time has dropped or the handset no longer holds a charge through the day. The 1200mAh capacity restores the runtime the phone delivered when new, making the swap worthwhile for any handset showing reduced standby or frequent low-battery alerts. No modification is required; the connector and dimensions align with the original design. A one-year battery pack warranty covers the replacement.

Verify Model and Part Number First

Before ordering, confirm the handset model number printed on the base or under the battery cover matches the supported list such as AM-CL33, AM-NX1, AM-F90, RP-BP61 or AM-ST40. Also check that the existing pack carries the MHB-901 part number to ensure the connector polarity and physical size are correct. The cell measures 66.78 x 16.7 x 5.96mm and weighs 50.0g, so the battery compartment must accommodate those dimensions.
