Two-Pack Li-Ion Replacement for Panasonic Headsets

This set contains two Kastar MX990 lithium-ion batteries rated at 3.7V and 1900mAh each, delivering 7.03Wh per cell. They replace Panasonic WX-B3030, WX-B3030M, BX-B3030 and CE-3030 packs in compatible headset systems. The twin pack suits users who need a ready spare for continuous operation.

Drop-In Fit with Built-In Protection

Each cell includes over-charge, over-discharge, over-voltage, over-current and over-heating circuits certified to UL1642 and CE. Installation is a direct swap: remove the old pack and insert the MX990. The only common error is forcing the connector if the polarity tabs are misaligned; check orientation before pressing home.

Verify Your Headset Model First

Confirm the headset is a Panasonic WX-T3020, WX-H3030, WX-H3050, WX-CH450 or WX-CT420 before ordering. The batteries will not fit other Panasonic series or third-party units. No charger is included, so ensure your existing charging cradle or dock accepts the original WX-B3030 form factor.

Questions about this item

How can I verify the Kastar MX990 batteries are charging correctly after inserting them into my Panasonic WX-T3020 headset?

The headset charging indicator should illuminate normally and the batteries will hold a charge through typical talk time, confirming the 3.7V lithium-ion cells are functioning.

What comes in the Kastar MX990 package and do I need a separate charger for these 1900mAh cells?

The box contains two MX990 battery packs only; they charge inside compatible Panasonic headsets such as the WX-H3030 or WX-CH450 so no extra charger is required.

Should I choose the Kastar MX990 2-pack or a single battery for my Panasonic WX-B3030M system?

The MX990 is sold exclusively as a 2-pack delivering 7.03 Wh per cell, giving you a ready spare for continuous operation with models like the WX-H3050 or WX-CT420.
