There are many advantages to running an auxiliary or second deep-cycle battery inside your car as opposed to mounting it under the bonnet, but you need to understand a couple of very vital safety points in order to do so safely. The Adventure Kings AGM deep-cycle batteries are perfectly suited to being mounted inside a car or a ute for a number of reasons.

Why would you want to run a deep-cycle battery inside your car? For starters, many modern vehicles have such small engine bays that running a second auxiliary battery under the bonnet can often be extremely difficult, or even impossible. Modern car engine bays are so cramped with new technology there simply isn’t room for a deep-cycle battery. Even if you do have the space to run a deep-cycle battery under the bonnet, you’ll then need to fork out more for an auxiliary battery tray and often spend hours relocating other under-bonnet components to make room for ?

It’s also a fact that like all electronics, batteries are much happier in cool, clean environments. That’s not to say you can’t run an auxiliary or secondary deep-cycle battery like the Adventure Kings AGM deep-cycle battery in your engine bay, but if you have the opportunity to mount it within the cabin of the car, it’ll prolong the battery’s life considerably.

The other massive bonus that mounting your Adventure Kings deep-cycle AGM battery within your vehicle’s cabin brings, is that you’ll then only need a very short run of cable between the battery and your 12v portable fridge. The shorter the cable run to the fridge, the less chance you’ll have of experiencing voltage drop, a natural process where the voltage coming from the battery can reduce by the time it reaches the fridge. If you’re running an Adventure Kings 60L or 80L fridge then the Secop BD35F or BD50 compressor is extremely efficient anyway, but the more voltage you can supply to the fridge, the longer it’ll run.

There’s even the option of running multiple Adventure Kings deep-cycle AGM batteries in the rear of the vehicle, for those campers who love staying at a picture-perfect campsite for multiple days in a row. We’ll discuss exactly how you can link multiple deep-cycle AGM batteries together inside a car’s cabin in a future news post.

So now you know why you would want to run a deep-cycle AGM battery within your cabin, but do you know what type of batteries can and can’t be run safely inside a vehicle?

The Adventure Kings AGM deep-cycle batteries feature a special completely-sealed construction type that prevents dangerous gases from being emitted from the battery during normal charging and discharging. Traditional deep-cycle batteries are known as ‘wet cell’ type batteries, and when they’re being charged by an isolator like the Adventure Kings Dual Battery System Smart Isolator or the CTEK D250SA DC/DC charger, the gases produced by the chemical reactions within the battery’s cells are potentially deadly if inhaled, and explosive as well. They’re fine to run under the bonnet, but you cannot run a traditional wet-cell battery within a vehicle’s cabin as it lacks airflow to safely remove those gases.

The Adventure Kings AGM deep-cycle batteries are of an Absorbed Glass Matt type. This is an entirely different type of battery technology that allows you to safely charge and discharge a battery inside your car’s sealed cabin. They’re sealed, and maintenance free – no need to top up the water like you would with a traditional wet-cell battery. They are perfectly suited to camping because they can store energy for long periods of time, and they’re also excellent at being recharged fast.

So how do you tell the difference between an AGM battery and a wet-cell deep-cycle battery? Firstly, an AGM battery like the Adventure Kings AGM deep-cycle battery range will almost always state on the label that it’s AGM. If it doesn’t say it – then it isn’t. More importantly, the Adventure Kings AGM battery range features no removable caps on the top of the battery, as they are maintenance-free.

We’ve developed the Adventure Kings AGM deep-cycle battery range to be the perfect way to power your Adventure Kings 12v fridge/freezer as well as other 12v accessories you need at camp light lighting. There are currently two sizes – 98aH and 115aH. The range features the same high quality you’ve come to expect from the entire Adventure Kings range of camping and 4WD gear, with features normally found only on AGM batteries up to twice the price. If you’re setting up an auxiliary battery system and want to run your second deep-cycle battery inside your car, then the Adventure Kings AGM deep-cycle battery range is exactly what you need.
