HIGHEST QUALITY CONSTRUCTION = IMPROVED PERFORMANCE!
Giant Power Batteries are built tough, and they are designed with more lead to create stronger connections between cells and heavier plates to increase the batteries reserve capacity. Giant Power Batteries are built to maximise life cycles, so you get reliable power every time!
This 140AH GIANT POWER AGM DEEP CYCLE BATTERY will give users reliable and easy battery power to run items like camping fridge's, 12V lights, phones, devices and other 12V / 24V camping accessories! Giant Power Batteries allow customers to focus on enjoying the great outdoors and are the perfect battery for camping because of their high quality construction and superior Reserve Capacity (RC) or Ampere Hour (AH) rating that will exceed your requirements.
The "140Ah" refers to the battery amp-hour rating, which measures the capacity or energy storage capability of the battery.
With a GIANT POWER 12V 140AH AGM BATTERY, you get massive battery capacity. Unlike some of our competitor's batteries who recommend only using 30-50% of the battery capacity with Giant Power, you get more value from your 12V AGM Batteries. 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.
For powering long distance journeys on recreational vehicles, choose deep cycle AGM batteries for a hassle-free experience. Deep cycle 12V 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 12V AGM batteries to provide high bursts of power when required such as starting an engine or providing emergency or backup power. 12V AGM’s also have high charge acceptance.
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.
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.
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).
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.
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 140Ah Giant Power Battery is ideal for up to a 1200W inverter. If you exceed this limit, it could damage the battery internally.

Giant Power 140AH AGM Deep Cycle Batteries are a premium quality battery that is designed to deliver industry-leading reserve capacities and life-cycle capabilities. Many innovative technologies, including a high AH ability and heavy duty ABS (heat resistant) rated case, make Giant Power Batteries the perfect solution for the challenging operating conditions of energy storage and other off-grid applications around Australia. The ideal combination of premium quality materials has catapulted Giant Power Batteries to becoming an Australian industry leader rated for both value and customer satisfaction.
All Giant Power deep cycle batteries are backed with an industry leading 5-year warranty and have a 5-star status among Australian users because they can take a hell of a beating, both physically and power-wise.
AGM Batteries use glass mat technology within the battery to absorb the acid, as opposed to standard flooded batteries where the acid is free flowing. This provides several key advantages over standard batteries, they are also 100% sealed, non-gassing and maintenance free (this means your batteries will never leak acid, even if damaged), and they will provide a significantly longer service and cyclic life (up to 2-3x longer than standard batteries). If you want to run a remote power system, you'll need the right Deep Cycle Battery to keep the current flowing. If you need reliable energy GIANT POWER 12V Deep Cycle Batteries are purpose-built specifically for these long-use applications.
*Please note installing this battery under your car bonnet as a starting battery or in electric golf buggies, mobility scooters may void your warranty. More suitable battery types for these applications are CCA-Rated.

As with all batteries, correct maintenance is important – particularly if it’s unlikely to be used for an extended period of time. With that in mind there are a few core points to follow:
1. Ensure your AGM battery is fully charged before being left. A fully charged AGM battery should read 13.00v or above. Ideally you need to ensure the final charge is done via an AGM optimised charging profile.
2. Never leave a battery on permanent charge (including trickle!) – despite having no free flowing acid inside, long term charging will cause the battery to dry out. Once fully charged and stored just ensure you charge the battery once a month overnight instead.
3. Try to keep your max discharge level to less than 80% . You can technically take AGM batteries lower than that, but the cycle life will reduce accordingly. For ultimate performance lifespan discharge to 50% then recharge back to 100%.
Note: Remember, the cycle life is a guide on the optimum life span of the battery – it doesn’t mean the battery will pack up and stop working – but you will notice considerably less running time once the cycle life has been achieved. Our Battery warranty does not cover loss of capacity as this is subjective to the usage, the frequency the battery is under and whether it’s been correctly charged.
Make sure that the battery is never discharged below 10.8 volts. If AGM batteries are discharged past this point permanent damage will occur. We recommend that you closely monitor the battery voltage / discharge levels via a digital volt meter or battery gauge.
Avoid Over Discharging & Protect Your Investment: Make sure that the battery is never discharged below 10.8 volts. If AGM batteries are discharged past this point permanent damage will occur. We recommend that you closely monitor the battery voltage / discharge levels via a digital volt meter or battery gauge. We also highly recommend the use of a low–voltage cutout device, these devices are not expensive and will protect your batteries by disconnecting any electrical loads from the battery before the batteries are over–discharged.
Avoid Overcharging - Use Automatic Chargers & Regulators: It is essential that any device used to charge your battery is regulated with a maximum bulk charge of 14.8 Volts and a float charge of no more than 13.8 Volts - The AGM or Flooded/Wet setting on most automatic charge devices is acceptable.

AGM Battery Range
Aussie Batteries & Solar request all AGM batteries be tested by a 12V auto electrician or a reputable testing facility such as Battery World. We will cover testing costs up to $20 per battery if the battery has failed.
Please note installing Deep Cycle Batteries under your bonnet without a heat shield or in electric golf buggies will void your warranty. We do not provide Warranty for AGM Batteries used in Golf Buggies or Mobile Scooters or Lithium Batteries in Mobile scooters. Only connect batteries of the same brand, capacity, size & age together: This is vital to protect the battery and its longevity.
