How To Charge Leisure Batteries: The Ultimate Guide
Whether you're an avid camper, love hitting the open road in your caravan, or spend weekends away in your motorhome, knowing how to charge your leisure batteries efficiently is crucial.

Leisure batteries are the lifeline of off-grid adventures, powering everything from your lights to your fridge when you're away from mains electricity. Here we dive into the best practices for charging leisure batteries, ensuring you never run out of power when you need it most.

Understanding Leisure Batteries


Before we delve into charging methods, it’s important to understand what leisure batteries are and how they differ from standard car batteries. Leisure batteries are designed to discharge a small amount of electricity over a long period, ideal for powering appliances when you are stationary. In contrast, car batteries deliver a large burst of power needed to start the engine but aren't suited for sustained energy delivery.

The first step in understanding and using a leisure battery is selecting the appropriate charger. A smart charger is highly recommended for leisure batteries because it can adjust the charging rate based on the battery's condition, preventing overcharging and extending the battery’s lifespan. Using chargers specifically designed for leisure batteries, such as the ones found at Simply Split Charge, will provide the correct charging profile.



Charging from the Mains

Charging your leisure battery from the mains is one of the most straightforward and efficient methods, especially when you have access to a stable power source such as at home or on a campsite. Connect your smart charger to the battery and then to the mains. The charger will do the rest, ensuring your battery is optimally charged. Remember to check the charger's instructions for specific details regarding charging times and settings.

Charging from the mains is a reliable and effective way to ensure your leisure battery is ready for your next adventure.

Using a Split Charge Relay

For those on the move, a split charge relay system can be an efficient way to charge your leisure battery. This system charges your leisure battery from your vehicle’s alternator while you drive, without the risk of draining your vehicle's starter battery. The relay automatically connects the leisure battery to the alternator when the engine runs and disconnects when the engine is off, ensuring both batteries charge appropriately without interference.

Solar Power Charging

Solar panels are an excellent way to charge your leisure batteries, especially if you’re parked for extended periods or prefer to stay off-grid. Solar chargers convert sunlight into electrical energy, providing a sustainable and eco-friendly charging solution.

Here at Simply Split Charge, we have a wide range of different options, from solid panels to folding ones that can fold up into a case. The key is to choose a solar panel system that matches your energy needs and ensure it's correctly installed for maximum efficiency.



Best Practices for Charging

Regular Charging: To maximise lifespan, avoid letting your leisure battery discharge completely if possible. Regular maintenance charging, even when not in use, maintains battery health. Try to charge your leisure battery every 4 to 6 weeks to prevent sulfation and capacity loss.

Monitor Battery Health: Use a battery monitor to keep an eye on charge levels and health. This will help you avoid deep discharges and identify when the battery needs charging. Storing your battery in a cool, dry place and keeping the terminals clean will also help preserve its health and efficiency.

Temperature Considerations: Battery charging efficiency can be affected by temperature. Keep your leisure battery in a relatively stable, cool environment for optimal charging.

Maintenance: Regularly check the battery terminals for corrosion and ensure they are clean and tight. For non-sealed batteries, check the electrolyte levels and top up with distilled water if necessary.

Efficiently charging your leisure battery ensures you have the power you need for your adventures, without the worry of running out of electricity at a crucial moment. Whether you’re charging from the mains, using a split charge relay, or harnessing solar power, understanding how to charge your leisure battery correctly is key to enjoying uninterrupted power.

Remember, the cornerstone of effective battery charging is regular maintenance and monitoring, as well as using top quality chargers. By following the best practices outlined in this guide, you can ensure your leisure battery serves you well for many trips to come.
