Compatible Camera Battery Pack

This Kastar MX990 two-pack supplies 1900 mAh lithium-ion cells rated at 3.7 V and 7.03 Wh each. They replace the original NEC 0910052 and 0910092 packs used in several NEC telephone handsets. The bundle suits installers or IT staff who maintain fleets of compatible desk phones.

Built-In Protection Circuitry

Each cell integrates over-charge, over-discharge, over-voltage, over-current and over-heating safeguards certified to UL 1642 and CE standards. The circuitry is internal, so no external charger firmware or special cables are required. Users simply swap the old pack for the new one and charge with the existing desk-phone cradle.

Check Handset Model Before Ordering

Verify that the handset label lists NEC DT330, DTL-12BT-1, UX5000 DG-12e or A50-012628-001, or that the original battery carries part number CS-NUX500CL. The pack also fits Listen LA-365 and iDSP RF receivers such as LR-5200-072, Media Interface M1 and Point M1 Microphone. Other NEC or Listen models are not supported.

Questions about this item

When will the Kastar MX990 lithium-ion cells need replacing?

The built-in protection circuit guards against over-charge, over-discharge, over-voltage, over-current and over-heating, which helps extend cycle life so the batteries last longer before replacement is needed.

What stops the MX990 pack from running longer during continuous use?

The 1900 mAh capacity and 7.03 Wh rating set the total energy available, so runtime ends when that stored charge is depleted.

How much heat or noise do the Kastar MX990 batteries produce in all-day operation?

The integrated over-heating protection circuit keeps temperature in check, and with no moving parts the batteries run silently during extended use.
