Let\u2019s start with the basics. The battery that powers your starter motor and turns your car\u2019s engine on when you hit the key is designed to deliver a high-speed burst of current for a short period of time. That\u2019s known as \u2018cold cranking amps\u2019. It\u2019s all about delivering bucketloads of power in quick bursts to power the starter motor and turn the engine over. On the other hand, a deep cycle battery is designed to deliver lower amounts of power for extremely long periods of time, so that it can run your fridge overnight, for instance.<\/p>\n
For the purposes of this article, we\u2019ll talk about two different types of 4×4 deep cycle batteries \u2013 wet cell, and AGM. There are other types of deep-cycle batteries, in particular lithium, but right now the average cost of a lithium battery is $1500 or more so they\u2019re still a long way from entering into mainstream use.<\/p>\n
Wet cell batteries are identified typically by the fact that they have removable caps to access the battery fluid inside each cell. However, not all wet cell batteries have these removable caps so the only real way to properly identify a wet cell deep cycle battery is by the label. The plates in the battery that store the electricity are suspended in the battery fluid and when the plates either receiving a charge of electricity, or when they discharge electricity, small amounts of toxic fumes are emitted. This means they cannot be run inside a vehicle cabin as they need constant fresh airflow.<\/p>\n
AGM batteries like the Adventure Kings 98Ah AGM deep-cycle battery<\/strong> <\/a>and the Adventure Kings 115Ah deep cycle AGM batteries<\/strong><\/a> use a different type of technology. Instead of using plates to store the electrical charge, they use Absorbed Glass Matt (AGM). This technology doesn\u2019t emit those toxic fumes when being charged or discharged, so it is completely safe to use within a vehicle cabin or a ute canopy.<\/p>\n <\/p>\n <\/p>\n These days the majority of campers are switching onto the fact that AGM 4WD batteries are the way to go. They\u2019re tough, built for 4WDing and the only real thing to be aware of is that they don\u2019t deal with excessive amounts of heat. That means they don\u2019t go great under bonnets where they\u2019re in close proximity to extremely hot turbochargers and exhaust systems. When subjected to extreme heat the absorbed glass matt can swell and seriously damage the battery.<\/p>\n![\"\"](\"https:\/\/news.emgcloud.net\/news\/wp-content\/uploads\/2018\/03\/Capture-105.jpg\")
