What is a leisure battery?

Ever wondered what keeps your campervan, caravan, or boat humming with energy for those extended trips? Meet the unsung hero - the leisure battery.

Unlike its cousin, the car battery, which is all about providing short, powerful bursts to kick-start your engine, a leisure battery plays a different game. It's all about delivering a consistent, steady stream of power over a long stretch of time.

Imagine setting sail on a boat or parking your campervan under the stars, and still being able to enjoy all the comforts of home. With a leisure battery, this dream becomes a reality. These powerhouses can smoothly run your appliances, from your cosy lights and refrigerator to your favourite TV shows, all while keeping your devices like phones and laptops fully charged. 

And that's not all! If you're a boat owner, a leisure battery is your silent partner, effortlessly powering your trolling motors as you navigate the waters. It is convenience and freedom, all packed into one powerful battery. 

Is a Leisure Battery Essential? 

Imagine being in the heart of nature, miles from the nearest electrical hook-up. 

Your devices are running low, and there's a dire need for a cuppa. In such situations, a leisure battery becomes more than a convenience; it's a lifeline. 

So, if you're an intrepid explorer or a peaceful angler, chances are, you need a leisure battery for your campervan or boat. You wouldn't want your adventure to be interrupted by a powerless situation, would you? 

Factors to Consider When Shopping for a Leisure Battery

Leisure batteries aren't one-size-fits-all commodities; there are several key factors you should consider to truly power-up your adventures.

1. Battery Size and Capacity 

First and foremost, consider the size and capacity of the leisure battery. Size matters because it needs to fit in your vehicle's dedicated space. Capacity, on the other hand, is about how long the battery can supply power. Always remember, bigger isn't necessarily better. It's about finding the perfect fit for you.

2. Battery Chemistry 

There are a few different types of leisure batteries, each with their own pros and cons. Conventional lead-acid batteries are often more affordable initially, but lithium batteries, although slightly more expensive, offer far longer lifespans and better efficiency. It's worth considering a lithium leisure battery for the long haul. 

3. Power Requirements 

Think about what you'll be using it for. If you're powering a small light and a mini fridge, you won't need as much juice as someone powering an electric stove and a complete entertainment system. Know your power needs before you go shopping. 

4. Charge Time and Discharge Rate 

How quickly does the battery charge, and how slowly does it discharge? A battery that charges quickly and discharges slowly will give you the most bang for your buck.

5. Cost and Warranty 

While cost shouldn't be the only factor, it's certainly worth considering. Remember to check the warranty too. A longer warranty often suggests the manufacturer has confidence in their product. For example, our Fogstar Drift Lithium Leisure batteries offer a 10 Year Warranty and a potential lifespan of 12-15 years.

If you've ever savoured the freedom of life on the road in a campervan, or time on the open water, you'll understand the importance of a reliable electrical setup. You can read more about calculating your battery bank size on our previous blog.

Deep Cycle Batteries vs. Starter Batteries: What's the Difference?

Picture this: you're settling down for a peaceful evening after an adventurous day out in your campervan. Suddenly, your lights flicker and die. Why? Your starter battery has run out of juice. You can avoid such scenarios by understanding the difference between deep cycle batteries and starter batteries. 

Starter batteries, aka car batteries or automotive batteries, are designed for short, sharp bursts of power. They start your campervan or boat engine and then recharge quickly. However, they don't handle sustained outputs well, like powering lights, refrigerators, or electronics for longer periods. 

Unlike its starter cousin, a deep cycle battery relishes the long haul. It provides continuous power over a longer period, perfect for running your appliances when you're off-grid. 

So, what makes a deep cycle battery tick? Its secret lies in the chemical make up and denser active material. This design allows it to discharge and recharge repeatedly without significant damage, hence the name 'deep cycle'. 

Now, you might be asking, "Can't I use a starter battery for my appliances?" Technically, yes – but it's akin to running a marathon in high heels. Starter batteries aren't equipped for sustained energy output. They'll wear out much faster and leave you in the dark, literally. 

To sum it up, if you need power for a split second to start an engine, reach for a starter battery. But for all your prolonged power needs, a deep cycle - or leisure - battery is your trusted ally.

Lithium: The Star of Battery Chemistry 

While there are various types of leisure batteries available, lithium leisure batteries really do steal the limelight. Why, you ask? Lets hit upon the benefits of choosing lithium over other battery chemistries. 

Lithium leisure batteries are significantly lighter, more compact and have longer lifespans than other battery chemistries. They have a higher energy density, meaning they can store more energy for the same size. Plus, they are maintenance-free and have a lower self-discharge rate. Sounds impressive, right? 

So, whether you're a weekend warrior or an experienced seaman, a leisure battery (particularly a lithium one) could be your best friend on your adventures. After all, who doesn't like uninterrupted power and the convenience it brings?


Thinking about buying, or replacing a leisure battery? The first step is to evaluate your power needs and find a battery that can keep up with your adventures. With the perfect leisure battery, you can chase those off-grid dreams without the fear of your power running out.
