Standard Horizon SBR-45LI 3200mAh Battery f/HX400

The Standard Horizon SBR-45LI 3200mAh Battery is the original replacement battery for Standard Horizon HX400 Series handheld VHF marine radios. Built to OEM specifications, this lithium-ion battery delivers reliable power for extended offshore communication and coastal operations where dependable radio performance is critical to safety.

The 3200mAh capacity provides extended operating time between charges, essential for multi-day fishing trips and maritime patrol scenarios where access to charging facilities is limited. Lithium-ion chemistry offers superior energy density compared to older NiCd or NiMH alternatives, meaning longer transmission time, longer receive time, and faster charging cycles. The SBR-45LI integrates seamlessly with HX400 radios and meets the electrical specifications required for safe, optimized radio operation—a critical detail often overlooked by aftermarket battery alternatives that can reduce radio performance or create compatibility issues.

This battery is engineered for commercial and recreational mariners who rely on VHF radios for distress calls, weather monitoring, and vessel-to-vessel coordination. Weekend anglers running coastal routes, commercial fishing operations, and maritime professionals operating in harsh salt-air environments benefit from using OEM batteries that maintain the radio's FCC-rated transmission power and receive sensitivity. Replacing worn or degraded batteries with genuine Standard Horizon equipment prevents the gradual performance decline that users often attribute to aging radios.

Standard Horizon has established itself as a trusted manufacturer of marine communications equipment for decades. Sourcing genuine OEM replacement batteries ensures compatibility, performance warranty coverage, and the confidence that your VHF radio will operate at rated specifications when safety depends on it.
