Replacement battery for Spectrum Analyzers

This lithium-ion unit replaces the original SM204 pack used in SM ENERGY ANRITSI MS2711A, MS2711B, MS2721A, MS2724C and MS2725C spectrum analyzers and OTDR instruments. It restores portable operation for field technicians who rely on those specific models.

11.1V 70Wh capacity match

The pack delivers 11.1 volts and 70 watt-hours, matching the voltage and energy rating required by the listed analyzers. A different voltage or capacity would prevent the instrument from powering on or meeting its specified run time.

Direct fit for listed instruments

The battery slots into the analyser’s existing compartment without adapters or cable changes. It frees the user from mains power during site measurements and adds no extra bulk beyond the original pack. Not suited for devices outside the MS2711, MS2721, MS2724 or MS2725 series.

Questions about this item

How long will the 70Wh rating keep an MS2721 spectrum analyser running in the field?

At 11.1V the pack stores 70Wh, so runtime equals 70Wh divided by the instrument's actual power draw — check the analyser's spec sheet for that figure.

Does the SM204 use a standard connector that fits the MS2721A and MS2725C without adapters?

The battery is listed as a direct replacement for part SM204 across the MS2711A, MS2711B, MS2721A, MS2724C and MS2725C models, so the original connector is used.

What physical space does the black 11.1V lithium-ion pack need inside the analyser chassis?

It is a direct-fit replacement for the SM204 part, matching the original battery cavity and mounting points in the supported spectrum analyser and OTDR units.
