Guest On-Board Battery Charger 15A / 12V - 3 Bank - 120V Input - 2713A

Guest On-Board Waterproof Battery Charger | 15A / 12V - 3 Bank (2713A)

The Guest 2713A is a compact, fully automated 3-bank on-board battery charger designed for boaters who need a reliable, multi-battery charging solution without the footprint of a high-amperage unit. Delivering a total of 15 Amps—distributed as 5 Amps per bank—this charger is the perfect fit for 12V, 24V, or 36V systems typically found on small to mid-sized fishing boats and runabouts.

Intelligent 5-Stage Charging

The 2713A features Guest’s advanced digital charging technology, which utilizes a 5-stage algorithm (Analyze, Soft Start, Bulk, Absorption, and Maintain). This process ensures that your batteries are not only charged to 100% capacity but are also conditioned to extend their overall service life. By independently sensing each bank, it prevents the common issue of overcharging a full starting battery while trying to charge a depleted trolling motor battery.

Key Features:

• 3-Bank Independent Charging: Provides 5 Amps per bank, allowing for the simultaneous charging of a starting battery and a 24V trolling motor bank, or a full 36V setup.

• 100% Waterproof & Shockproof: Rated IP67, this charger is completely sealed in a rugged, potted housing to withstand the vibrations, salt spray, and moisture of the marine environment.

• Smart Maintenance Technology: Automatically monitors the batteries and only provides a charge when needed, allowing you to leave the charger plugged in all winter without "boiling" the batteries.

• Universal Compatibility: Optimized for all 12V Flooded (Lead-Acid) and AGM batteries.

• Safety & Protection: Includes integrated safety features such as Reverse Polarity, Over-Voltage, Over-Current, and Over-Temperature protection.

• LED Status Indicators: Features separate LEDs for each bank that indicate the charging status and alert you to potential wiring or battery faults.

• Compact and Lightweight: The flangeless, extruded aluminum design makes it one of the easiest 3-bank chargers to mount in restricted spaces.

Why Choose the Guest 2713A?

The 2713A is the ideal choice for boaters who typically have longer periods between trips (e.g., weekenders). While the 5-amp-per-bank rate is slower than the high-performance 10-amp models, it is significantly more efficient and safer for the battery than a manual portable charger and easily recovers batteries to full capacity overnight.

Pro Tip for Installation:

Since the 2713A is often used in smaller compartments, ensure the cooling fins on the aluminum housing are not obstructed. Even at 15 amps, the unit generates heat during the "Bulk" charging phase. Mounting it vertically on a bulkhead is the most efficient way to allow heat to dissipate naturally.
