What the battery replaces

This Estry 3G4000 is a 7.2 V 2000 mAh nickel-metal hydride pack built to match the original specifications for DSC 3G4000 and LE4000 cellular communicators. It carries ISO 9001, RoHS, CE, UN 38.3 and MSDS certifications and includes over-charge, over-discharge, over-voltage and short-circuit protection. The pack measures 87.1 x 51.75 x 14.65 mm and weighs 213.8 g.

Compatibility and limits

The battery fits only devices that accept the listed part numbers such as 2AAP2200MAH, 1P-3BH7220, 3G4000BATT, 3G4000USA, 6PH-H-AA2200-S-J26, 3G4000-BATT or FB-51. Buyers whose communicators use a different voltage, chemistry or form factor should look elsewhere. It is not suitable for lithium-ion-only equipment or for models requiring a higher capacity than 2000 mAh.

Deciding specification

The critical figure is the 7.2 V 2000 mAh Ni-MH rating; the communicator must be designed for that exact voltage and chemistry. Confirm the part number on the original battery before ordering.

Questions about this item

Will the 7.2V 2000mAh pack fit my existing 3G4000 Cellular Communicator without modification?

How can I verify the battery is charging correctly after installation?

The communicator's status LED will show a steady charge indicator once the 7.2V pack reaches full capacity, typically within a few hours.

Does the box include a charger or only the 213.8g Ni-MH battery pack?

Only the replacement battery pack is supplied; a compatible charger must be purchased separately.
