No, it doesn’t snow here in Milwaukee… at least, I’ve never seen it. But we do get some pretty cold days in the winter.
On those days, I’ll be firing up the lights on our patio. When the sun goes down, I’ll want some security lights on. I’ll want the furnace running. We’re going to need a good battery to keep us warm during the winter months.
Come spring, I’ll want to be able to run the AC unit. I’ll want the power to run all the lights in the yard and the fans for the party. Yes, I’m a party animal in the summer.
I won’t even talk about what it’s like when we really celebrate it up and have the parties going for 4th of July. All of this uses a lot of power, so we need to use a good battery.
So, what are the deep cycle batteries for? What am I looking for? What are the best deep cycle batteries? These are all important questions.

| 4 X TROJAN BATTERY T-105 PLUS 6V DEEP CYCLE FLOODED 225 Ah. | Upgrade Pick |  |
1. Battle Born LiFePO4 Deep Cycle Battery
Pros:
- Ideal for backup, off grid, marine or solar power applications
- Very long life battery
Cons:
- Basic warranty is only 3 years
- Requires several batteries to store enough power
Deal Extreme markets this strong contender as one of their budget-minded products, but the Battle Born LiFePO4 Deep Cycle Battery is much more than just a bargain bin battery.
This 100 amp-hours 12V battery is fully active (as opposed to flooded lead acid batteries), so there’s no danger of it leaking acid. It’s also maintenance-free, and just requires you to recharge it to maximize its lifespan. Battle Born markets this rechargeable battery as suitable for marine, solar and RV use, and claims that it is one of the best deep cycle batteries on the market today.
Battle Born offers a full three year warranty on the batteries, but leave out the big claim on the battery’s lifespan. The manufacturer claims that it should last for 3000 to 5000 deep cycle recharges, which can equate to between 15 and 25 years of use, so you should be able to see the full lifespan of the battery in your home with just a few batteries.
2. Universal Power Group 12V 100Ah Solar Wind AGM SLA DEEP Cycle VRLA Battery 12V 24V 48V
Pros:
- Safe for the Environment
- Comes in different sizes: 100Ah, 150Ah, or 200Ah
- Absorbs a Large Amount of Solar Energy
- Can be Stored for Long Periods of Time
Cons:
- Gets heavy quickly
- Not as light as gel-cells
- Expensive
This great battery is non-spillable, meaning that it will not leak acid and contaminate surroundings the way that lead-acid batteries can. And it does not contain liquid acid.
This battery is made for boats, back-up power, and many other times of deep-cycle loads. It is generally safe to leave a 12-volt deep-cycle battery connected to the electrical system with the solar panels attached to it, even if the solar panels are not connected. One expert pointed out that it is usually not a good idea to charge the battery with more than 20% of the capacity of the battery, in case the battery were to overheat.
This battery is ideal for small to mid-size PV systems. You can check the storage capacity of the battery by looking at the Amp Hour Rating on the label. The higher the number, the longer the battery will work in cold weather.

Frequently Asked Questions (FAQ)
What is the best deep cycle battery on the market?
For boat owners, finding a deep cycle battery you can rely on is especially important. There's nothing more disappointing than heading out on your fishing trip or voyage across the ocean only to discover that your battery can barely start the motor.
That's why there is so much emphasis on getting the right battery. Saft batteries are frequently pushed and recommended by manufacturers because they are well vetted and have a reliable track record.
Other manufacturers like Lifeline have been a leader on the market for years. The Lifeline Battery Industries produces batteries that can be used for many purposes, including starting, lighting, deep cycle and industrial applications.
If you have a vehicle like a boat, you will need an engine battery that can handle the power your engines require and also the power needs for the accessories like the radio, navigation devices, spotlights, fish finder and all the rest.
What is the best deep cycle battery Australia?
The best deep cycle batteries Australia are without a doubt the Numax batteries.
It is easy to find so many reasons why Numax batteries are the best and the oldest brand of deep cycle battery.
Numax is growing organically by both influencing the market and the consumer needs in Australia.
Many people are switching to Numax deep cycle battery because it dominates the market and it has been the best brand for Australia for such a long time.
What is the best deep cycle battery for solar?
Solar panels of all sizes require a great amount of energy to run. Inside your house, the power from the sun can charge your batteries and electric cars, while in your RV/backyard trailer, it can power lights, the refrigerator and other electronics.
While standard car and boat batteries are great for car starting and boat starting applications, they usually aren't suitable for long-term deep cycle use.
A deep cycle battery, on the other hand, is made up of a grid of lead plates submerged in only inches of distilled water. This constricted level of water makes it more difficult to access the stored energy in the battery.
This "difficult-to-get-to" energy is what deep cycle batteries excel at. It's also the reason why they usually cost more than car/boat batteries.
Who makes the best deep cycle RV battery?
For many potential shoppers, the search for the best deep cycle battery contains confusion about the product itself, as well as which brands are the best to invest in and purchase.
There are a number of criteria that need to be considered prior to shopping for the best deep cycle RV battery. For example, the correct battery charger must be used to charge the batteries and the best deep cycle batteries require a specialized deep cycle battery charger.
Also, there are a number of different types of deep cycle batteries manufactured by numerous companies worldwide. A few of the most common manufacturers are Banner, Deka, Trojan, Odyssey, Lifeline, Interstate, and more.
Each deep cycle battery manufacturer offers a number of different types of deep cycle marine batteries and different series with varying amp hours. The series is determined by the reserve capacity of the batteries.
