Three-pack replacement batteries

This Kastar MX990 pack contains three lithium-ion cells rated at 1900mAh, 3.7V and 7.03Wh each. They are built as direct replacements for the Listen LA-365 battery and compatible headset units. The cells carry UL1642 and CE safety certifications with integrated protection against over-charge, over-discharge, over-voltage, over-current and over-heating. The set suits users who run Listen iDSP RF receivers, LR-5200-072, M1, Media Interface or Point M1 Microphone equipment.

Verify device model before ordering

Check that your unit accepts the Listen LA-365 form factor and 3.7V chemistry. The batteries are not universal; they only fit the specific Listen models listed. Confirm the battery compartment dimensions and connector orientation match the original LA-365. No charger is included, so ensure you already have a compatible charging solution for these cells.

Low self-discharge and thermal protection

The built-in protection circuit limits temperature rise during normal discharge cycles. Lithium-ion chemistry keeps self-discharge low between uses, so spares hold charge well. No active cooling is required and the cells run silently. The safety features prevent excessive heat build-up even under continuous load in compatible Listen receivers and microphones.

Questions about this item

What comes in the 3-pack and do I need a separate charger?

The pack contains three Kastar MX990 lithium-ion batteries rated at 1900 mAh and 3.7 V. A charger is not included and must be purchased separately if you do not already own one compatible with Listen LA-365 cells.

Should I choose the 3-pack or buy single batteries for my Listen iDSP RF Receiver?

The 3-pack supplies three 7.03 Wh cells at once, giving you spares for continuous use with the LR-5200-072, M1 or Point M1 microphone. Single units are not offered in this listing.

How long will a 1900 mAh battery run my Listen LA-365 device in practice?

Each cell delivers 7.03 Wh at 3.7 V with built-in over-charge, over-discharge, over-voltage, over-current and over-heating protection. Actual runtime depends on the receiver's power draw, but the capacity matches the original LA-365 specification.
