Choosing the best electric fence batteries 2022: Buyer’s guide

Electric fence chargers are the heart of your electric fence system. Thus, it would be best to find the right electric fence charger for your electric fencing.

But, to operate well, the best electric fence charger needs the best battery. So let’s examine the guidelines to find the best unit.

1. Charger types

how long does electric fence battery last

Best electric fence chargers are divided into three categories: DC battery-operated chargers, AC, and solar energizers.

Therefore, to find the best battery, you need to choose the right battery-operated charger and make the system optimal. You also must know how the fence charger works.

You will have to check the voltage and wattage levels to find the right solution for your fencing system. Otherwise, you will have serious power issues, and the fence cannot work.

Remember that some chargers also come with a metal rod, and they require the proper grounding system.

So, check if all components support the fencing, and then choose the batteries.

2. Battery components

Our reviews included AGM/SLA, lithium, and deep cycle batteries.

In addition, all of the units presented are rechargeable, offering a longer lifespan and countless uses.

It would be best to select the spill-proof batteries as they can endure lower and higher temperatures, harsh conditions, impacts, external forces, and pressure.

They will also ensure better performance between the charging sessions, so you don’t have to recharge them so soon, especially solar units.

3. Joules

Choosing the battery also depends on how many joules the charger utilizes. So, it’s a good idea to know its power and optimal strength to see if it will fit your confined areas.

If you want to protect your property from more minor pests, then a 0.5-joule rating is sufficient.

But, for more giant invaders, such as deer, for instance, a 15-joule rating is usually optimal.

So, check the power numbers before the final decision.

4. Alternatives?

Many farmers consider car batteries as the 12-volts units for fences. However, car batteries are not recommendable, as they can cause multiple complications.

If you have to choose, go with the deep cycle batteries. Unlike car batteries, these products are created to be repeatedly discharged and then recharged again.

Car batteries are always the cheapest option, yet they can never provide you with the quality and optimal performance necessary for the fencing system.

5. Design and system

Here you can refer to potential, power, strength, and overall structure and performance. It would help if you considered these factors to find the optimal batteries.

First, they will last longer. In addition, they will offer a stable electrical current, and the charger will empower the lines for the best productivity.

Next, they will be safe and secure for prolonged use and lifespan and create a more robust physical and psychological barrier to your animals and predators.

Finally, suitable power levels ensure and enhance maximum performance and potential, so the batteries will make the fencing system solid and reliable for more robust uses and broader applications.

Frequently Asked Questions

What size battery do I need for an electric fence?

Fences run by chargers that require batteries. Typically, batteries utilize either 12-volt or 6-volt systems.

However, smaller chargers or specific solar units require 6-volt batteries or even D-Cell fence batteries.

How long will the 9-volt battery last electric fence?

They can be for several months, depending on the use and heavy-duty or lighter fencing projects. Typically, they last between 3 and 9 months, depending on the Ah system.

For instance, a 55Ah battery has a 90-day of little life. In addition, a 150Ah battery has a 250-day of nominal lifespan.

Finally, a 90Ah battery has a 150-day of nominal lifespan. Search for the Ah data to find the best solution.

What is the best 12V battery for an electric fence?

You can go with the Interstate Batteries 12V 12Ah Battery, as it’s a deep cycle battery. However, you can also look for other Interstate 12V batteries or similar brands and models.

It’s crucial not to use car batteries, as these will only complicate your fencing system.

In addition, they cannot provide the necessary power and quality as regular DC batteries.

What type of battery for the electric fence?

Our experts suggest either 6-volt or 12-volt rechargeable deep cycle batteries. Unfortunately, they are not included with fence chargers.

They will provide enough power and strength to the corresponding chargers, utilize them, and provide the best electric protection to your livestock and property.

Also, they have specific charging periods, last longer, and you can use them for multiple projects.

However, you still must check and recharge the batteries to maintain safety and security operations and systems. You can use voltage meters for such operations.

How to charge an electric fence battery?

Depending on the model, you can either insert the batteries into the chargers or simply attach the energizers to the external batteries.

It would help if you connected the grounding terminal of the charger to the grounding rods with a piece of fence wire.

Next off, you will connect the charger’s Positive Terminal to the fence with another piece of wire.

Finally, you will turn on the charger.

Can I connect a solar panel directly to the battery?

best rechargeable electric fence battery

Generally, yes, you can, but there’s a hack.

Solar panels higher than 5 watts must not be connected directly to the battery. Instead, you should join them via a solar charge controller to protect them against overcharging.
