Kastar MX990 3-Pack for Listen LA-365

The Kastar MX990 kit supplies three lithium-ion replacement batteries and a matching AC wall charger for the Listen LA-365 cell. It also powers compatible Listen iDSP RF receivers including the LR-5200-072, M1, Media Interface and Point M1 Microphone. Each battery delivers 3.7 V and 1900 mAh for a total energy rating of 7.03 Wh. The pack suits venues, tour operators and rental houses that run multiple Listen devices simultaneously.

Sustained charging with foldable flat plug

The wall charger accepts a universal 100 to 240 V input at 50 or 60 Hz and provides a steady 4.2 V, 600 mA DC output. LED indicators show red while charging and green once the cells reach full capacity or standby. The foldable flat-pin design keeps the charger compact during transport and storage. This arrangement supports continuous overnight replenishment of all three batteries without overheating or voltage sag.

7.03 Wh capacity decides runtime

The 7.03 Wh rating per cell determines how long a Listen receiver operates between charges. Buyers who need longer single-battery runtimes or higher voltage configurations will find this capacity insufficient. No other capacity or chemistry option is offered in this pack.

Questions about this item

How much heat or power draw should I expect from the Kastar MX990 charger when it runs continuously?

The charger draws AC 100–240 V at 50–60 Hz and outputs DC 4.2 V at 600 mA, so its steady-state power draw is low and heat remains minimal during all-day use.

Which Listen devices must I already own for these MX990 batteries to work?

The batteries fit the Listen LA-365 pack and the iDSP RF Receiver models LR-5200-072, M1, Media Interface and Point M1 Microphone.

Will the Kastar MX990 charger still charge correctly if I keep using an older Listen receiver that takes the LA-365 battery?

Yes — the charger’s 4.2 V 600 mA output matches the original LA-365 spec, so it charges legacy Listen gear that uses that battery without issues.
