EMMITS AGM Batteries

AGM model batteries are the most used for caravans and other recreational vehicles, since their characteristics are perfect for this use. They are maintenance-free, gas-free, compact and can be installed in any position.

You may be familiar with AGM caravan batteries, which although they have the same functions as other similar batteries, they have other characteristics. In particular, they have the function of storing electrical energy for the motor. But also for the alternator when it is not enough to provide enough energy for other devices in the vehicle.

These types of batteries are characterized by being used when high power is required - such as when starting the vehicle -, in addition to having pressurized safety valves. These valves have the quality of preventing leaks of the gas they contain inside.

On the other hand, AGM batteries are also known as dry batteries and are the best batteries for caravans thanks to their high resistance to multiple charge and discharge cycles. In addition, they charge very quickly, the storage time is optimal and they have a high specific power, they do not require any maintenance and last a long time.

Without a doubt, knowing the characteristics of AGM batteries, you will want to have them in your vehicle. But do they actually adapt to all types of vehicles? As we mentioned before, these are batteries that do not require maintenance and are leak-proof, due to their characteristics and have the quality of being the ideal energy accumulator.

Therefore, AGM caravan batteries are recommended for upper mid-range cars as well as sport utility vehicles. These types of vehicles have start-stop systems, as well as braking energy recovery, as well as advanced accessories. Keep in mind that if your vehicle has an AGM battery, it must be replaced with the same one. And in case you have an EFB battery and want to switch to AGM, you should do so only in case there is a higher power demand or requirement from the battery.

The AGM batteries They feature a sealed design, which prevents acid leakage and makes them safe for indoor use. The electrolyte is absorbed into a glass fiber separator, which helps maintain high energy density and low internal resistance. This translates into greater efficiency and load capacity, as well as greater durability over time.

In addition, AGM batteries are maintenance-free, which means that it is not necessary to add distilled water periodically as with conventional batteries. This makes them ideal for applications where it is difficult or inconvenient to access the battery regularly.

Another advantage of AGM batteries is their ability to operate in different positions. Unlike conventional lead-acid batteries, AGM batteries do not require being upright, making them more versatile and easier to install in different spaces.

AGM batteries find applications in a wide variety of sectors due to their features and advantages. In the automotive sector, these batteries are used in recreational vehicles, caravans and boats, as their sealed design makes them safe for use in confined spaces.

In the renewable energy sector, AGM batteries are used in energy storage systems, such as solar panels and wind turbines. Their high load capacity and resistance to adverse environmental conditions make them an ideal choice for these applications.

Additionally, AGM batteries are used in the telecommunications sector, where a reliable power supply is required for base stations and backup systems. Their sealed design and ability to operate in different positions make them ideal for these applications.

If you are wondering what type of battery is best for your caravan, AGM or gel, the answer is clear: AGM batteries are the best option in most cases.

Here we explain why:

Higher starting power: AGM batteries are known for their excellent starting power, making them the best option for starting your caravan's engine, even in cold weather.

Smaller size and weight: Are more compact and lighter than gel batteries, allowing you to optimize the space in your caravan.

Most economical price: AGM batteries are more accessible than gel ones, which makes them a more attractive option for your pocket.

Greater availability: AGM batteries are easier to find than gel ones, making it easier for you to purchase and replace them.

Simple maintenance: Although AGM batteries are not completely maintenance free, require less attention than gel ones, since they do not need to be refilled with water as frequently.

Useful life: While gel batteries have a slightly longer lifespan, the difference is not significant enough to justify the higher cost and other disadvantages.

If your AGM battery has become deeply discharged, don't worry, there is still hope to revive it. Here we'll explain to you how to do it:

  1. Charge with a specific charger for AGM batteries:
  • It is essential to use a charger designed for AGM batteries. These chargers have a specific charging profile that helps recover discharged batteries without damaging them.
  • Follow the charger manufacturer's instructions to charge correctly.
  1. Slow charging:
  • A trickle charge at low current (around 0.1C) can help recover the battery cells.
  • This process may take several hours, but it is the safest way to resurrect a deeply discharged AGM battery.
  1. Desulfation:
  • Sulfation is a natural process that occurs in batteries when they are deeply discharged.
  • Some AGM chargers have a desulfation mode that can help remove sulfates from the battery plates and improve battery performance.
  1. Repeat the process:
  • You may need to repeat the charging and desulfation process several times to fully recover the battery.
  1. Monitor the battery:
  • It is important to monitor the battery while charging and after charging to ensure it is recovering properly.


  • Do not use a conventional charger to charge a discharged AGM battery. These chargers can damage the battery.
  • Do not attempt to start your vehicle's engine with a discharged AGM battery. This can damage the battery and motor.
  • If the battery does not recover after several attempts, it may need to be replaced.
