Trickle Battery Charger

12V & 24V Trickle Battery Chargers for Long-Term Maintenance

Prevent flat batteries and extend the lifespan of your power system with our premium range of trickle battery chargers. When a vehicle, caravan, boat, or motorcycle is left idle for weeks or months, the battery naturally self-discharges. If left unchecked, this can lead to permanent damage and reduced capacity. A high-quality trickle charger provides a steady, low-amperage maintenance charge to keep your battery at optimal voltage, ensuring it is ready for action the moment you turn the key.

Smart Charging with Built-In Overcharge Protection

Traditional older-style chargers can boil or damage batteries if left connected indefinitely. Our selection features the highly regarded Victron Blue Smart IP65 range, which utilises intelligent microprocessors to automate the entire charging cycle. Once the battery reaches 100%, the unit automatically switches to a low-current maintenance mode. This built-in overcharge protection means you can safely leave the charger connected to your vehicle for months at a time without concern.

• Automatic Maintenance Mode: Safely monitors and floats the voltage to preserve battery health.
• Multi-Chemistry Compatibility: Suitable for maintaining AGM, Gel, Lead-Acid, and modern Lithium (LiFePO4) battery banks.
• Bluetooth Connectivity: Monitor voltage, current, and charge history directly from your smartphone.
• Weather Resistant Design: IP65 ratings ensure protection against dust and water ingress, perfect for garages and carports.

Ideal for Cars, Caravans, and Marine Applications

Whether you are storing a classic car over winter, parking your caravan between trips, or maintaining a marine battery system at the dock, a dedicated maintenance battery charger is a small investment that prevents costly replacements. By utilising dedicated car battery chargers equipped with smart float profiles, you ensure your starting and deep cycle batteries remain healthy. For most standard setups, our 12V battery chargers in the 4A to 5A range provide the perfect balance of top-up speed and safe, long-term floating. We also offer dedicated 24V models for trucks, buses, and larger off-grid arrays.

How to Choose the Right Trickle Charger

Selecting the correct maintenance charger depends primarily on your battery voltage and capacity. Follow these guidelines to find the perfect match for your garage or storage setup:

1. Match the Voltage: Ensure the charger matches your battery bank. A standard automotive or caravan system requires a 12V unit, while larger industrial or heavy-vehicle setups may require a 24V model. For smaller motorcycles or vintage cars, a selectable 6V/12V 1.1A unit offers excellent versatility.

2. Select the Appropriate Amperage: For pure maintenance of a fully charged battery during storage, a lower amperage output (1.1A to 5A) is highly effective and gentle on the cells. If you occasionally need to recharge a deeply depleted battery quickly, consider opting for a 4A or 5A model rather than a 1.1A model, as it provides a slightly faster recovery before dropping into float mode.

3. Verify Chemistry Compatibility: If you have upgraded your RV or 4WD to lithium, ensure your chosen maintainer has a dedicated lithium charge profile. All Victron Blue Smart chargers in this collection safely manage both traditional lead-acid and modern lithium cells.
