Direct Replacement Battery

The Kastar MX990 is a 3.7V lithium-ion cell rated at 1900mAh and 7.03Wh, built to replace the original NEC 0910052 and 0910092 packs. It fits the DT330, DTL-12BT-1 and UX5000 DG-12e handsets, so users of those legacy devices regain factory runtime without modification.

Upgrade From Depleted Originals

When the stock cell no longer holds a charge through a full shift, this pack restores the talk and standby time the handset was designed for. The jump is worth it whenever the original battery shows swelling, rapid voltage drop or requires daily recharging.

Capacity for Extended Shifts

At 1900mAh the cell comfortably powers a typical cordless handset through a standard business day of mixed talk and idle time. Runtime shortens under continuous high-volume use or in areas with weak signal where the radio draws peak current.

Not for Multi-Cell Packs

Buyers needing a multi-cell pack for a base station or a higher-voltage radio system will find this single 3.7V cell incompatible. It also does not suit devices that require a proprietary smart-battery protocol beyond simple voltage and thermistor connections.

Questions about this item

Will the 3.7V 1900mAh pack fit the NEC DT330 battery compartment?

Yes, the MX990 matches the original NEC 0910052 and 0910092 form factor for the DT330 and DTL-12BT-1 models.

How do I install the MX990 without triggering the over-voltage protection?

Insert the battery with the contacts aligned, then power the camera on before placing it on a charger for the first cycle.

When should I replace the 7.03 Wh Li-Ion cell?

Replace it when run time drops below half of the original 1900mAh capacity or the pack swells.
