FAQs

What are the different types of deep cycle batteries?

Deep cycle batteries come in three main types; AGM, gel, and lithium chemistries. Lithium 12V deep cycle batteries offer plenty of benefits over the other options here. They’re the most efficient, have a longer lifespan, and have a higher usable capacity so that you get the most from your setup.

How long do 12V deep cycle batteries typically last?’

With the right care, a lithium 12V deep cycle battery can go on for up to 10 years or more. This is significantly longer than lead-acid alternatives so you always have the power you need.

How to install a lithium 12V deep cycle battery?

Set up your battery in a secure location, hook it up with the right gauge wiring, and make sure it’s paired with the right charger. As with any power solution, always stick to the manufacturer’s installation guide.

How do I charge a 12 volt deep cycle battery?

Use a lithium-compatible charger for safe, efficient charging. Try not to overcharge or use a charging profile that’s not compatible.

How do I calculate load on my 12V deep cycle battery?

Add up the wattage of all devices you plan to run, divide by 12, and multiply by the hours you think you'll use to figure out your amp-hour needs.

What are the different applications of 12V deep cycle batteries?

They’re used for caravans, 4WDs, boats, off-grid homes, camping setups, and backup power systems.

Is a 12 volt, 100Ah deep cycle battery enough for camping?

Yes, a 100Ah lithium battery will run fridges, lighting, and small electronics for several days; enough for pretty much any camping setup.

Can I leave my 12V deep cycle camping battery on trickle charge?

Yes, if you use a lithium-compatible charger with a float or maintenance mode.
