Replacement battery for land-mobile radios

The Estry S3x2E is a lithium-ion pack rated at 7500mAh and 11.1V. It replaces the original battery in Anritsu Field Master Pro units and a wide range of Land Mobile Radio models including the MS271xE, MS272xC, MT8213E and MT8220T. Radio technicians and field engineers who need a direct-fit spare for these instruments will find the correct voltage and capacity here. It is not suited for devices that require a different voltage or connector layout.

Protection circuit limits continuous current

The pack includes over-charge, over-discharge, over-voltage and short-circuit safeguards that interrupt output when thresholds are exceeded. This means the battery will shut down rather than sustain a load that draws more current than the protection circuit allows. Users running high-power transmit modes should verify that their radio's peak draw stays within the pack's unspecified continuous rating. The built-in protection cannot be bypassed or adjusted.

Rigid enclosure with integrated connector

The hard plastic case measures 213.11 x 58.51 x 22.22mm and weighs 615.0g, matching the original form factor so it seats securely in the radio's battery compartment. A moulded connector on the pack engages the radio's contacts without cables or adapters. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, confirming compliance with transport and substance regulations. No separate charger is included; the radio's existing charging cradle or desk charger is used.
