Battery Pack for Listen Devices

This four-pack of Kastar MX990 lithium-ion cells replaces the Listen LA-365 battery used in iDSP RF receivers and Media Interface units. Each cell delivers 3.7 volts and 1900 milliampere-hours for 7.03 watt-hours of capacity. The pack suits crews who need spare power for extended sessions.

Sustained Runtime and Protection

Built-in circuits guard against over-charge, over-discharge, over-voltage, over-current and over-heating during continuous operation. The protection helps maintain stable voltage through long recording or broadcast periods. UL1642 and CE compliance confirms the cells meet recognised safety requirements. Cycle life benefits from the consistent charge management.

Thermals and Power Draw

Lithium-ion chemistry keeps heat output low under normal receive loads. No active cooling is required and the cells run silently in belt-pack or handheld housings. Power draw follows the host device’s consumption profile without adding parasitic drain. The compact 3-by-2-by-3-inch form factor fits existing battery compartments.

Questions about this item

Does the 3.7V 1900mAh Li-ion cell stay cool when the Listen LA-365 runs all day?

The MX990 includes built-in over-heating protection and meets UL1642 and CE safety standards, so the cell remains stable during extended use in the Listen iDSP RF receiver or Point M1 microphone.

Which devices must I already own for these four MX990 packs to work?

You need a Listen LA-365 battery slot or one of the compatible units — Listen iDSP RF receiver, LR-5200-072 advanced intelligent DSP RF receiver, M1 media interface or Point M1 microphone.

Will the MX990 fit and charge correctly in my older Listen LR-5200-072 receiver?

Yes, the pack is listed as a direct replacement for the LA-365 cell used in the LR-5200-072, M1 media interface and Point M1 microphone, so it seats and charges without modification.
