Compatible radio models

This replacement battery fits the Yaesu FT-4VE, FT-4VR, FT-4VX, FT-4XE and FT-4XR two-way radios. It matches the original SBR-28 and SBR-28Li part numbers. The pack uses lithium-ion chemistry and carries ISO9001, RoHS and CE certifications. A built-in protection circuit guards against overcharge, over-discharge, over-voltage and short circuits.

Capacity and voltage

The cell delivers 1750 mAh at 7.4 volts for 12.95 Wh of energy. Physical dimensions are 79.00 x 51.56 x 14.50 mm and weight is 75.0 g, matching the factory pack so the radio’s battery latch and case fit without modification. The fully decoded chip communicates with the radio exactly like the original unit.

Upgrade considerations

This unit replaces a worn or lost OEM pack for the listed Yaesu models; it is not a higher-capacity alternative. Buyers who need extended runtime beyond 1750 mAh or a different voltage platform should look elsewhere. The battery reaches peak performance after two or three full charge cycles.

Questions about this item

How long will the 1750mAh capacity last during continuous transmit on my FT-4VX?

Runtime depends on transmit power and duty cycle; the 12.95Wh rating gives a baseline for calculating expected use.

Does the battery get hot during all-day monitoring on the FT-4VR?

Normal operation stays within the 60°C storage limit; the lithium-ion chemistry and protection circuit manage heat during extended receive.

Which original Yaesu part numbers does this SBR-28Li replace?

It replaces Yaesu SBR-28 and SBR-28Li packs used in FT-4VE, FT-4VR, FT-4VX, FT-4XE and FT-4XR radios.
