Battery Powered Electric Fence Energisers are particularly suited for users who require a temporary or semi-permanent electric fence. A battery-powered energiser may also be the only option for users who need an electric fence at a particularly remote location or where mains power is unavailable.
The main benefits of choosing a Battery Powered Electric Fence Energiser are the ability to set up and easily relocate your fence whenever and wherever it is required, without incurring additional costs unless you're making changes to your system.
On the downside, the battery will need regular charging, and it can be heavy and cumbersome. It is worth noting that adding a solar panel to a battery-powered fencing system can significantly extend the time between charges. Make sure the battery is rechargeable, as disposable batteries cannot be recharged. How do you know if your battery is rechargeable? Alkaline batteries are not rechargeable, other types like AGM (Absorbent Glass Mat) batteries which is a type of sealed lead-acid (SLA) battery are. These are often used in situations where a higher performance and longer lifespan is required compared to traditional flooded lead-acid batteries.

| Rechargeable batteries like lead-acid (AGM or Gel), lithium-ion, and NiMH are ideal for long-term use, offering cost savings and environmental benefits over time. They are well-suited for regular use on electric fence energisers, especially when used on larger or more demanding fences. | Disposable batteries such as alkaline and zinc-carbon are typically used in smaller, occasional-use energisers. While they have a lower upfront cost, their single-use nature means they are more expensive over time if used frequently. |

FAQ’s about Battery Energisers
can you use a car battery for electric fencing?
Yes, you can use a car battery for an electric fence, but it's not ideal. Standard car batteries are designed for short bursts of power, so they may wear out quickly with continuous use. A deep-cycle battery is a better option as it’s built for sustained energy output. Make sure the voltage matches your energiser (typically 12V) and recharge the battery regularly to maintain performance.
how long does an electric fence battery last?
Deep-cycle batteries (e.g., AGM or lead-acid) can last several weeks to a few months on a single charge, especially when paired with an efficient energiser and used with solar assistance to extend life. Make sure to read the product description carefully to assess if the battery is long lasting.
how to charge an electric fence battery?
Select a charger compatible with your battery type (e.g., lead-acid, AGM, or lithium). Attach the charger's positive (red) clamp to the battery's positive terminal and the negative (black) clamp to the negative terminal.
