When your camping and running a 12v fridge, most battery manufactures will recommend running the battery down to 50%, which is normally about two days of autonomy. With Giant Power Batteries, you get double the power usage due to the thicker lead plates and quality construction this means you get up to four days power autonomy.

The Advantages of AGM batteries:

For powering long distance journeys on recreational vehicles, choose deep cycle AGM batteries for a hassle-free experience. Deep cycle AGM batteries can repeatedly discharge to approximately 80% and recharge without losing capacity to deliver high power in a short amount of time. They are also resistant to vibration making them suitable for all kinds of terrains in Australia.

1. AGM Batteries deliver a higher output

AGM batteries have a lower internal resistance than any other lead acid battery. This enables AGM batteries to provide high bursts of power when required such as starting an engine or providing emergency or backup power.  AGM’s also have high charge acceptance.

2. AGM Batteries are spillproof

AGM batteries do not have any free electrolyte in the cell as is it suspended in the glass mats. Placing the battery upside down is not not recommended.

3. AGM Batteries are durable

AGM batteries are designed to be sturdy, handling vibration particularly well. The plate groups are compressed into each cell; this compression holds everything together.. They are also resistant to a condition known as acid stratification, where the acid and water separate over time.

4. AGM Batteries are resistant to vibration

The electrolyte soaked glass mats in between each lead plate act like a damper. The plates are compressed between the mats making AGM batteries highly resistant to vibration. This makes them suitable for vehicles that operate in high vibration conditions (i.e. ATVs, 4WDs & SUVs).

Charging Your AGM Battery

We Suggest The PROJECTA PRO-CHARGE RANGE simply connect the battery with the clamps or fixed eyelet harness and plug the charger into a wall for fast and efficient charging.

AGM batteries are very sensitive to overcharge and over-discharge, improper charging and discharging will lead to the reduction of battery life. So the proper charging process is very important. An AGM battery can last years in your car, boat or RV, and keeping it charged with the right battery charger is the best way to make sure you get the most life from it. On regular basis at 25°C for 12V deep cycle AGM batteries, float charge voltage is 13.5V~13.8V, cycle charging voltage is 14.4V~15.0V. 

DC-DC Charging For AGM Batteries

Why not look at a DC to DC charger that is suitable for LiFePO4 and lead acid: AGM, Gel & Calcium Batteries, and allows you to re-select the battery during charging. With the memory function of this battery to battery charger, you don't need to re-select the same battery type every time.

 ** This 190Ah Giant Power Battery is ideal for up to a 1200W inverter. If you exceed this limit, it could damage the battery internally.

Giant Power 12V 190AH AGM Deep Cycle Battery

AGM Batteries are Perfect for Use in a Range of 12V Power Applications

AGM batteries can resist damage from extreme temps and vibration. The absorbed mats give AGM batteries a sponge-like resistance to vibrations. A regular car battery's sensitive internal components can break apart if you shake it hard enough. Its lead plates are hanging from a sturdy metal in liquid. In the battery industry, there are two ways that AGM batteries are rated:


While battery cycle life is about how many times your AGM battery will discharge before dropping to under 80% of original capacity the service life is directly related to how many years the battery chemistry will last until it is less than 80% capacity from the original state.

AGM batteries can resist damage from extreme temps and vibration.

The absorbed mats give AGM batteries a sponge-like resistance to vibrations. A regular car battery’s sensitive internal components can break apart if you shake it hard enough. Its lead plates are hanging from a sturdy metal in liquid. Even if you don’t break the plastic case, it’s common for car batteries to die if you rattle them hard enough. an AGM battery’s fiberglass mesh keeps that water trapped because it’s packed so tightly to the lead plates. On top of that, the sealed design holds the water vapor in, and only if you overcharge it will a molecules of water vapor escape. An AGM battery’s sealed, spillproof design allows them to pass the specific transportation regulations. You can ship them by air, deliver them by mail, etc. It might be odd to think of spilling a car battery, but you should understand that standard car batteries are not as durable as AGM batteries. They’re more like a full cup of water with a sippy cup lid. If you turn it over, it spills or leaks. AGM batteries are more like sealed soda cans. You can transport them, and they won’t spill or leak if turned on their side. 

AGM batteries have special valves that protect their service lifespans.

AGM batteries also have valves regulating the hydrogen and oxygen allowed to escape during charging. They fall under a broader category of valve-regulated, lead-acid (VRLA) batteries, also called maintenance free. If you’ve never thought much about maintaining your car battery, it might be thanks to this special one-way valve that essentially keeps evaporated water from leaving the battery case. The battery’s fundamental chemistry is still based on lead, sulfuric acid and water. When you draw power, the acid molecules move to the lead plates, leaving water and lead sulfate — and sending an electrical charge out of the positive post. Removing the sulfuric acid from the solution creates a chemical reaction between the paste on the plates. Recharging a battery works in reverse: Electricity goes in, making the liquid more acidic.

AGM batteries recharge faster than regular batteries.

Fiberglass mesh mats soaked in electrolyte carry current faster than liquid electrolyte. Yes, that’s how AGM batteries can deliver big bursts of power even if they’re drained. It’s also how AGM batteries recharge faster than regular batteries. That low internal resistance means AGM batteries can give more amps and accept more amps when they recharge.

Standard batteries need more voltage than AGM batteries to recharge because regular batteries have higher internal resistance. To keep them from overheating, they can only take a few amps at a time at that high voltage.

This means AGM batteries need a special AGM charger. They can take a lot of amps in a short period of time — but an AGM battery charger must keep its voltage lower than 14 volts to avoid ruining the AGM battery. AGM batteries are 12 volts, like all car batteries, and can handle some higher voltage, but only up to a certain point. If a car alternator charges an AGM battery with a voltage higher than 15 volts, it can damage an AGM. 

Highest Quality Engineering

AGM batteries are a kind of valve-regulated, lead-acid (VRLA) battery, which is part of why AGM batteries last so long. VRLA batteries have a one-way valve regulating how much hydrogen and oxygen can escape when the battery recharges. Normally, when a standard battery recharges, electricity splits the water in the electrolyte into hydrogen and oxygen, which mostly gets absorbed back into the electrolyte. The rest of the hydrogen and oxygen escapes through vents in the case, and the battery loses water. Water loss can kill a car battery, and that’s why you should occasionally refill your standard batteries with distilled water. You don’t have to maintain VRLA batteries the same way. Their one-way valves keep the gases in the battery, effectively preventing water loss.

190Ah AGM batteries can outperform a regular car battery in almost every way because of their design. A low internal resistance means AGM batteries can give more amps and accept more amps when they recharge. 

Benefit From Proven Performance

AGM batteries hold their charge well and are less likely to sulfate when compared to regular wet cell batteries (conventional batteries types). Because of this, they are an excellent choice for vehicles that require off-season storage. AGM batteries can be mounted in more flexible orientations than conventional batteries because the liquid is sealed inside the battery. Because the liquid electrolyte flows freely inside conventional batteries, they must be mounted and stored upright to prevent leakage. Another advantage of the electrolyte being absorbed and held by a separator suspended inside the battery is that it is more resistant to vibration, a vital plus for 4WDs or other vehicles that operate on uneven surfaces.

While both AGM and Lithium batteries provide reliable power, here are some notable differences that set them apart:

  • AGM batteries are more affordable than Lithium batteries.
  • AGM batteries have a shorter cycle life compared to Lithium.
  • AGM batteries can only be discharged to 80% Depth of Discharge (DoD) while Lithium Iron Phosphate batteries can be discharged to 100% DoD in an emergency.
  • Lithium batteries are approx. 50% lighter in weight compared to AGM batteries.
  • Lithium batteries have an active Battery Management System (BMS) which will shut down the battery to protect it if the temperature, voltage or current is outside the nominated range.

When it comes to deciding between an AGM Battery and a Lithium Battery, the application, intended use, expected life expectancy and budget play a major role - both Lithium and AGM are excellent deep cycle battery choices as they deliver excellent performance and efficiency at a competitive price.
