The Kastar MX990 set contains four 3.7V 1900mAh lithium-ion cells rated at 7.03Wh each. They are built as direct replacements for Panasonic WX-B3030, WX-B3030M, BX-B3030 and CE-3030 battery packs used in several headset systems.

Compatibility limited to listed Panasonic models

These batteries fit the Panasonic WX-T3020, WX-H3030, WX-H3050, WX-CH450 and WX-CT420 headset units. They will not work with cameras or headsets that require a different voltage, form factor or connector type.

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating safeguards certified to UL1642 and CE standards. Normal operation stays cool and quiet with no audible fan or active cooling required.
