Standard Horizon SBR-41LI 1750mAh f/HX280 & HX380

The Standard Horizon SBR-41LI 1750mAh lithium-ion battery is a replacement power source designed for the HX280 and HX380 portable radio transceivers. This battery delivers 1750mAh capacity, providing extended talk time and standby duration for two-way communication in field operations, emergency response, and remote site work where reliable RF connectivity is mission-critical.

The SBR-41LI represents an upgraded capacity compared to the earlier FNB-V105LI, allowing extended operational periods between charging cycles. The 1750mAh capacity is optimized for the power demands of compact marine-band and commercial-grade handhelds, where weight and portability matter as much as runtime. Lithium-ion chemistry delivers consistent voltage output throughout the discharge curve, ensuring stable transmit performance and receiver sensitivity even as the battery depletes. Standard Horizon engineered this battery as the factory-standard supply for the HX380, reflecting confidence in its performance and longevity profile.

This battery is ideal for professionals and operators who rely on portable VHF or marine band communication—coast guard personnel, marine salvage teams, offshore vessel crews, search and rescue units, and field technicians in remote areas. Users who maintain multiple HX280 or HX380 units benefit from carrying spare SBR-41LI batteries to maintain continuous operational readiness without dependency on shore power. The compact 3 × 2 × 5-inch footprint and 0.25 lb weight ensure minimal impact on overall radio portability, a critical factor during extended patrol or emergency response deployments.

Standard Horizon handheld radios are recognized in marine and public safety sectors for durability and clear audio performance. The SBR-41LI battery maintains Standard Horizon's commitment to compatible, reliable power supplies that integrate seamlessly with their radio platform and match factory specifications for safety and performance.
