Waterproof Marine Battery Charger IP68, 12V/24V, 5–10A (Sterling ProSport)

The Sterling ProSport Waterproof Battery Charger delivers professional-grade charging and maintenance for your boat’s batteries. With a fully sealed IP68 design, this charger is built to endure water spray, salt fog, and humidity, making it ideal for installation in engine bays, bilges, or exposed deck areas. Its compact, epoxy-encapsulated housing protects internal components from moisture and vibration, ensuring a long service life in harsh marine conditions.

The PS125 model (Code 03864-125) is a dedicated 12V charger rated at 5A, perfect for smaller vessels (approx. 3–5 m) with a single battery up to ~120 Ah. It will keep one battery topped off and healthy even during long periods of non-use. This model is an excellent choice for small powerboats, RIBs, or personal watercraft that use one starting battery, providing peace of mind that your engine will start reliably every time.

The PS1255 model (Code 03864-1255) offers enhanced versatility with dual outputs – it can charge two separate 12V batteries at 5A each simultaneously or one 12V battery at 10A for faster charging, and it also supports 24V charging at 5A for systems with two series-connected batteries. This makes it ideal for larger boats (5–8 m) or those with multiple battery banks (e.g., a start battery plus a house battery) as well as for yachts running 24V electronics. The charger intelligently distributes current and monitors the temperature of each bank, preventing overload and overheating to protect your batteries.

Key features and benefits of the ProSport marine charger include:

• Multi-Stage Smart Charging: Automatically cycles through bulk, absorption, and float stages to ensure batteries reach 100% charge without overcharging. This technology maximizes battery performance and longevity by applying the right charge at the right time for each battery’s needs.
• LED Status Display: Provides at-a-glance status of power on and charging progress. You can easily tell when the batteries are fully charged or if any attention is needed, even in low-light conditions.
• Comprehensive Protections: Built-in fuses and safety circuitry guard against reverse polarity, short circuits, and surges. The unit meets marine safety standards and is ignition protected, meaning it won’t ignite fumes in the engine compartment. Charge your batteries with confidence and safety.
• Rugged Durability: Constructed with corrosion-proof materials and fully potted electronics, the charger withstands the pounding of waves and vibrations of the boat. It operates across a wide ambient temperature range (e.g. -10°C to +50°C) without de-rating, delivering full power in hot engine rooms.
• Universal AC Input: Accepts 110–230V AC input, allowing it to be used at marina shore power worldwide or with onboard generators. The output automatically adjusts to your battery type, providing optimal charging for lead-acid, AGM, and GEL batteries alike.

By choosing this charger from Five Marine, you benefit from Sterling Power’s proven marine charging technology – a wise investment to safeguard your batteries. Enjoy trouble-free voyages knowing your boat’s electrical system is in good hands and your batteries are always efficiently charged and maintained.
