What You'll Learn
Electric fence batteries should last around 30 days
Firstly, it is important to use the correct type of battery for an electric fence. Deep cycle batteries are specifically designed for electric fences as they can provide a lower output for a prolonged period. Automotive batteries, on the other hand, are designed for high power over a short period and will be quickly drained by an electric fence.
The power requirements of the electric fence will also impact battery life. For example, a 12V 100 ampere-hour deep cycle battery will last approximately 59 days on a clean fence, but this duration will be shorter if the fence is weedy, as vegetation can draw voltage and amperage to the earth. Additionally, the presence of animals can affect battery life, with some users reporting that bears can cause the battery to last a shorter amount of time.
Environmental conditions can also impact the longevity of electric fence batteries. For instance, batteries should be protected from water and direct sunlight, as they do not respond well to heat. Furthermore, the amount of sunlight can impact the effectiveness of solar panels used to charge electric fence batteries, with users reporting issues with solar charging during the winter months when the sun is often obscured by clouds.
To prolong the life of electric fence batteries, it is recommended to change or charge them before they are completely discharged. Most battery energisers will automatically stop working when the battery reaches about 80% discharge, and it is best to avoid letting the battery go below 60% to ensure maximum service life. Some users recommend having two batteries, so one can be charging while the other is in use, ensuring a constant power supply for the electric fence.

Deep cycle batteries are better than car batteries
Electric fences are typically powered by 12-volt batteries. While car batteries can be used, deep cycle batteries are a better option for several reasons.
Firstly, deep cycle batteries are designed to be discharged and recharged frequently. In contrast, car batteries are meant to deliver high power for a short duration and do not perform well when deeply discharged. Using a car battery for an electric fence will significantly reduce its lifespan and prove costly in the long run.
Deep cycle batteries also offer greater cyclic stability. Car batteries have thin, perforated plates to maximize the surface area for the chemical reaction that produces a surge of power when starting an engine. However, this design compromises cyclic stability, making them less suitable for applications like electric fences where repeated discharge and recharge cycles are common.
Additionally, deep cycle batteries provide flexibility in terms of recharge frequency. A 100 amp-hour deep cycle battery, for instance, can last about 59 days on a clean or weedy fence. This extended duration reduces the need for frequent recharging, making it more convenient and practical for electric fence applications.
Moreover, deep cycle batteries are widely available and reasonably priced. Local retailers often offer deep cycle marine batteries with Amp Hour ratings at affordable prices. This accessibility makes deep cycle batteries a more viable option compared to car batteries, which may not always be readily available for electric fence use.
In conclusion, while car batteries can be used to power electric fences, deep cycle batteries are a superior choice due to their design, cyclic stability, longer lifespan, and cost-effectiveness. Deep cycle batteries are specifically engineered to handle frequent discharging and recharging, making them a more reliable and efficient power source for electric fences.

Solar panels can be used to charge batteries
The longevity of an electric fence battery depends on several factors, such as the type of battery, the draw of the fence, and the weather conditions. On average, a 12V deep cycle battery will last approximately 30 to 59 days before requiring replacement or recharging. However, it is recommended to avoid discharging the battery below 60% to prolong its life.
When using solar panels to charge electric fence batteries, it is important to consider the power requirements of the fence and choose a suitable solar panel size. A 20W solar panel, for example, can produce around 4 amps on a sunny day, which is sufficient for trickle charging. Additionally, a solar charge controller can be used to prevent overcharging the battery.
For those seeking a more comprehensive solution, solar-powered energiser bundles are available that include solar panels, fence energisers, and batteries specifically designed for electric fencing. These bundles provide a complete system for powering an electric fence and can offer greater convenience and efficiency.
By utilising solar panels to charge electric fence batteries, individuals can benefit from reduced maintenance, lower costs, and a more sustainable energy source for their fencing needs. Solar energy harnesses the power of the sun, providing a renewable and environmentally friendly alternative to traditional battery charging methods.

Keep batteries above 60% discharge to prolong life
To ensure your electric fence battery lasts as long as possible, it is important to keep it above a 60% discharge. This is because all batteries last longer if they are not fully discharged often. Most battery energisers will automatically stop working when the battery reaches about 80% fully discharged, but letting the battery go below 60% will reduce its service life.
It is recommended that you change or charge your battery before it runs completely flat. The deeper the battery is discharged, the shorter its life. For example, one user reported that their 105Ah battery lasted a week before it was half discharged. They recommended charging it at 50% discharge once a week, which should make the battery last 9 years.
Another user reported that their 12V battery lasted 30 to 40 days before they had to switch to a solar panel with a charge controller. They also recommended keeping the battery above 60% discharge to prolong its life.
It is worth noting that some factors can cause the battery to drain more quickly, such as weeds or grass touching the fence line, drawing voltage and amperage to earth. Therefore, it is important to keep any vegetation away from the wires to ensure the battery lasts as long as possible. Additionally, the more bears the fence comes into contact with, the shorter the battery will last.
To summarise, keeping your electric fence battery above 60% discharge will help to prolong its life. This can be achieved by regularly charging the battery before it reaches a low charge, and by ensuring that the fence is clear of any vegetation or other factors that may drain the battery.

Vegetation touching the fence can drain the battery
Vegetation touching an electric fence can cause the battery to drain. Grass, bushes, or tree branches that touch the wire can create a short circuit, reducing the power going through the fence line. This can lead to a complete power drain, causing the fence to lose its effectiveness in containing animals. Therefore, it is important to regularly monitor the fence and trim any vegetation that might be touching it.
The impact of vegetation on the battery life of an electric fence depends on various factors, including the type of vegetation, the amount of rainfall, and the growth rate of the grass. In areas with high rainfall or fast grass growth, a higher-powered energizer is recommended to compensate for the increased vegetation pressure on the fence line. Additionally, the type of fence can influence the impact of vegetation. Electric netting is more susceptible to vegetation touching the fence line compared to a single strand of wire or polybraid.
To mitigate the effects of vegetation on battery life, some sources suggest using a solar panel or trickle charger to extend battery life. Regularly checking the voltage and recharging when it drops below a certain level is also recommended. However, it is important to note that car batteries, while usable, may not be the best option due to their design for short-term, high-power output rather than continuous use.
Overall, vegetation touching an electric fence can impact the battery life by creating a power drain. Proper maintenance, such as trimming vegetation and selecting appropriate energizers, is crucial to ensuring the fence's effectiveness and prolonging battery life.
