The 120ah Deep Cycle Battery stands as a robust and essential component for applications demanding reliable, sustained energy in Australia and beyond.

As innovations continue, these batteries offer increasingly sophisticated and efficient energy storage. Understanding their specifications, applications, and care is crucial for maximising their longevity and securing dependable, long-term power autonomy.

The main difference lies in their design and purpose. A regular car battery (a starter battery) is built to deliver a large, short burst of current to start an engine and is then quickly recharged. A 120ah Deep-Cycle Battery is designed for sustained, lower current draws over a long period and can handle being repeatedly discharged and recharged down to a low state of charge without significant damage. This makes it ideal for powering accessories and appliances.

The duration depends on the total current draw of your appliances. The 120Ah rating means it can theoretically supply 120 amperes for one hour (or 6 amps for 20 hours, for example). To estimate runtime, divide the 120ah Deep Cycle Battery’s capacity (120Ah) by the total continuous current draw (in Amperes, A) of your connected devices. For example, if your total draw is 5 Amps, the theoretical runtime is 120 Ah/5 A=24 hours. Always allow for a depth of discharge limit (e.g., don't go below 50%) to protect the battery, so the usable capacity would be less than 120Ah.

It's not recommended to use a standard car battery charger designed for starting batteries. These chargers often charge at a very high current and may not have the necessary voltage regulation or multi-stage charging profile required for a deep cycle battery. Using an inappropriate charger can lead to overcharging, overheating, and significantly reduce the battery's lifespan and efficiency. Always use a charger explicitly designed for deep cycle batteries, often referred to as a smart or multi-stage charger.

The depth of discharge (DOD) refers to how much energy is pulled out of the battery relative to its total capacity. A high DOD (discharging the battery heavily, say to 80%) places a greater strain on the battery's internal plates. The less you discharge the battery before recharging (lower DOD), the higher the total number of life cycles you will get out of it. For example, consistently only discharging a battery to 50% DOD might give you twice the number of cycles compared to routinely discharging it to 80% DOD.
