Lead-acid batteries are the most common type of leisure battery and have been around for over 150 years. They are widely available and are known for their reliability and affordability. They are also commonly found in automobiles, boats, and other vehicles.


Lead-acid batteries work by using a chemical reaction to store and release electrical energy. The battery contains two lead plates, one positive and one negative, that are submerged in an electrolyte solution made of water and sulfuric acid. The lead plates act as electrodes, and the electrolyte solution acts as the electrolyte. When the battery is charged, the lead plates on the positive electrode are converted into lead peroxide, while the lead plates on the negative electrode are converted into lead. When the battery is discharged, the lead peroxide on the positive electrode is converted back into lead, while the lead on the negative electrode is converted back into lead sulphate. This chemical reaction creates a flow of electrons, which generates electricity.


Lead-acid batteries have several advantages that make them a popular choice for leisure batteries. They are widely available, and replacement batteries are easy to find, even in remote areas. They are also relatively inexpensive when compared to other types of batteries, such as lithium-ion batteries. Additionally, lead-acid batteries are relatively low maintenance, and they can be easily refilled with distilled water if the level of the electrolyte solution drops too low.


However, lead-acid batteries also have several downsides. They are relatively heavy and bulky, which can be a challenge when space is at a premium in a van conversion or RV. They also have a shorter lifespan compared to other types of batteries, such as lithium-ion batteries. Additionally, lead-acid batteries can be damaged if they are discharged too deeply, and they require regular maintenance to ensure they are functioning properly.


In summary, lead-acid batteries are a popular choice for leisure batteries due to their reliability and affordability. However, they do have some downsides, such as shorter lifespan, and they can be relatively heavy and bulky. If you're planning on using a lead-acid battery for your leisure battery, it is important to consider these downsides and make sure that it is the right choice for your specific needs.

Sizing your Leisure Battery


When it comes to choosing a leisure battery, one of the most important factors to consider is the size of the battery needed. Sizing your leisure battery correctly will ensure that you have enough power to run your devices and appliances, and that you can stay off-grid for as long as you need. In this section, we will explain how to determine the size of leisure battery needed, including how to calculate total power consumption and how to calculate days without external power.


The first step in determining the size of your leisure battery is to calculate your total power consumption. This involves adding up the power usage of all the devices and appliances that you plan to run off your leisure battery. To do this, you will need to know the power usage (measured in watts) of each device and how long you plan to use it each day. For example, if you plan to run a 100-watt laptop for 4 hours a day, your total power consumption for that device would be 400 watt-hours (100 watts x 4 hours). Once you have calculated the power usage for all your devices, add them together to get your total power consumption.


The next step is to calculate how many days you want to be able to go without external power. This will depend on your specific needs and how long you plan to be off-grid. For example, if you plan to be away for a weekend, you may only need to be able to go 2 days without external power. On the other hand, if you plan to take a longer trip and be away for a week, you may need to be able to go 7 days without external power.


Once you have determined your total power consumption and the number of days you want to be able to go without external power, you can use this information to calculate the size of the leisure battery you need. The most common unit of measurement for battery capacity is amp-hours (Ah). To calculate the size of the leisure battery you need, you will need to divide your total power consumption (measured in watt-hours) by the voltage of your leisure battery. For example, if your total power consumption is 10,000 watt-hours and you have a 12-volt leisure battery, you will need a leisure battery with a capacity of approximately 833 amp-hours (10,000 watt-hours / 12 volts = 833.33 amp-hours).


It's important to note that when sizing your leisure battery, you should always go for a slightly larger capacity than you think you'll need. This will give you a buffer, and ensure that you don't run out of power unexpectedly. Additionally, it's important to consider the discharge rate of the battery when selecting the size. A leisure battery with a low discharge rate will last longer than one with a high discharge rate.


In summary, determining the size of leisure battery needed is an important step in choosing the right one for your off-grid setup. It involves calculating your total power consumption and determining the number of days you want to be able to go without external power. It's important to consider the discharge rate of the battery when selecting the size, and always choose a slightly larger capacity than you think you'll need to ensure a buffer. In the next section, we will explore how different types of leisure batteries affect sizing, and provide tips on how to maximise the use of your leisure battery.

Lead-acid batteries, for example, have a lower energy density compared to lithium-ion batteries. This means that a lead-acid battery of the same size will have a lower capacity and will not last as long as a lithium-ion battery. Additionally, lead-acid batteries have a shorter lifespan and require regular maintenance, such as topping up with distilled water. This means that you may need to replace your lead-acid battery more often and also consider the maintenance cost.


Lithium-ion batteries, on the other hand, have a higher energy density and can store more energy in a smaller package. They also have a longer lifespan and require less maintenance. This means that you can choose a smaller size battery and still have the same or even more capacity and performance than a lead-acid battery. Additionally, lithium-ion batteries have a higher discharge rate, which means they can handle more power and deliver it more quickly. This makes them a great option for running high-power appliances and devices.


AGM batteries, like lead-acid batteries, have a lower energy density and shorter lifespan than lithium-ion batteries, but they are sealed and require no maintenance which makes them a good option for sealed applications such as boats and RVs.


When it comes to sizing your leisure battery, it's important to consider not only the capacity and performance, but also the maintenance requirements of the battery type. With lithium-ion batteries, you can choose a smaller size battery and still have the same or even more capacity and performance than a lead-acid battery, and with less maintenance required. This means you can save space and reduce the overall cost of your off-grid setup. On the other hand, if you choose a lead-acid battery, you may need to choose a larger size to achieve the same capacity and performance, and also factor in the cost of regular maintenance.


It's also important to note that when sizing your leisure battery, you should always choose a battery that is designed for deep cycling. Deep cycling refers to the process of repeatedly discharging and recharging a battery. Deep cycle batteries, such as lithium-ion batteries and AGM batteries, are specifically designed to handle this type of use and will perform better and last longer than batteries that are not designed for deep cycling.


In summary, when choosing a leisure battery, it's important to consider not only the capacity and performance, but also the maintenance requirements of the battery type. Lithium-ion batteries offer the best performance and longest lifespan, and AGM batteries offer maintenance free operation. Lead-acid batteries are the most traditional option, but require regular maintenance and have lower energy density. Factors like the size and power consumption of the appliances you want to run, and the number of days you want to go without external power should also be taken into account when determining the size of the leisure battery. In the next section, we will provide tips on how to maximise the use of your leisure battery and make the most out of your off-grid setup.
