Cameron Sino 2500mAh 7.4V Battery for Yaesu FT-25E/FT-65E/FTA-250L

Replacement battery for Yaesu two-way radios

This Cameron Sino lithium-ion pack replaces the original SBR-25LI, SBR-26LI, SBR-28 and SBR-28Li cells in Yaesu FT-25E, FT-4VE, FT-4VR, FT-4VX, FT-4XE, FT-4XR, FT-65E and FTA-250L handsets. It delivers 2500mAh at 7.4V for extended talk time. The integrated protection circuit guards against overcharge, over-discharge, over-voltage and short circuits. Buyers needing a higher-capacity pack or a different voltage should look elsewhere.

Capacity and voltage define the practical limits

The 2500mAh / 18.50Wh rating sets the energy available per charge cycle. Runtime scales with transmit power, duty cycle and ambient temperature; the supplier notes optimal performance arrives after two or three full charge and discharge cycles. Using a low-quality third-party charger can reduce service life. The pack must not be stored above 60°C or 140°F and must never be disassembled or exposed to fire or water.

Simple swap but connector alignment matters

Installation consists of removing the old pack and sliding the new one into the battery compartment until the connector seats fully; many users find the process straightforward with help from online videos. The most common issue is an improperly seated connector, which prevents the radio from powering on. The package includes shock-absorbing foam for transit protection. No tools are required beyond what the radio itself provides.
