Deep Cycle Batteries
Everything you Need to Know to Make an Informed Decision
Are you a fishing or hunting enthusiast? Do you need a battery for your boat’s electric engine and accessories? Want to take to the road with peace of mind? Our experts are here to help!
This buyer’s guide has been put together to help outdoor enthusiasts better understand deep cycle batteries (DC batteries) and how to look after them properly.
Psst! Don’t worry about memorizing everything:
you’ll find a summary table at the end of this guide!
Do you need to power up a fridge, an electric engine or any other applications in the great outdoors? A DC battery is just what you need!
Unlike a starter battery, which is designed to provide a boost of energy over a short period of time, a deep cycle battery is a specialized bank of energy that produces a stable and continuous flow of energy.
It allows you to use your electronic applications any time, anywhere!
A DC battery is a bit like a gas tank…
A chemical reaction:
The energy generated by a battery is essentially a chemical reaction that varies according to a number of factors: age of the battery, vibrations, temperature, use, discharge %, how the battery is charged, type of charger used, etc.
This is why it’s really important to choose a battery that meets your needs and to maintain it properly.
Difference between a gas tank and a battery:
Unlike a gas tank, a battery can only be charged/discharged a certain amount of times throughout its lifetime. In other words, you must replace your battery once it has completed a certain amount of charge/discharge cycles.
Factors to consider
Do you have enough space for your battery? If you have big needs, but not much space, you’ll have to adapt your energy consumption.
Are you going to drive on off-road trails that generate a lot of vibration? Remember that certain batteries are specially designed for this level of impact!
Is mobility important for you?
Will you need to move your battery around? Do you struggle lifting heavy objects? Our light batteries are easy to lift and allow you to move around freely.
Required capacity and number of hours
What will your DC battery be used for (engine, light, radio, etc.)?
How many amperes do your applications require?
Will you use your battery for a few hours or several days?
Number of times you use the battery per year
How many times do you think you’ll go fishing this year? This will help you figure out the number of cycles you’ll need.
Will you be able to charge it?
Will you be able to charge the battery at the end of the day or will you have to wait until the end of your 3-day trip?
Most DC batteries must be charged within 24 hours of using them.
Like to keep things simple?
Certain batteries require less maintenance than others. To find out more, take a look at the table at the end of this guide!
How many ampere hours
(Ah) do I need?
To figure out how many Ah you’ll need (by doing the below calculation), start by thinking about how long your fishing trips tend to last and how many amperes your applications require per hour.
Generally speaking, the latter can be found on the engine or the application itself.If not, take a look at the reference table to calculate your engine’s consumption – all you’ll need is the thrust (lbs) of your engine.
of your application X hours
of your fishing trips
*We strongly suggest you leave room for unforeseen circumstances (wind, current, or even extra hours spent on the lake – if there’s a fish, make the most of it!).
maintain your battery
If you use and maintain your battery properly, it will last a lot longer and will provide maximum capacity during your fishing trips.
Design and technology
Certain batteries can provide more cycles because they have been designed to withstand poor maintenance.
How to get the most out of your DC battery
Inspect the battery to ensure it’s well charged
- Verify the liquid level (batteries requiring watering maintenance)
- Clean the terminals to improve the electrical connection
- Visual inspection: is the battery leaking? Is it cracked or inflated?
Each time you charge your battery, it’s important to wait around 6 hours before reusing it. Otherwise, you may wear the battery out prematurely.
using your battery
Keep an eye on how much you use your battery in one go
The amount of cycles a battery can provide varies according to the capacity % (Ah) you use. In other words, someone that tends to use 80% of their battery’s capacity won’t have as many cycles as someone who uses just 30%.
The table at the end of this guide will help you compare batteries with different technologies.
Within 24 hours
of using your battery
Charge the battery within
24 hours of using it
The longer you leave a battery discharged after a deep discharge, the more likely it will get damaged. Deposits will form on the surface of the plates, which will have a negative impact on the performance of the battery.
We strongly recommend you charge a DC battery within 24 hours of using it to avoid damage such as sulfation.
Once a month
Level of the electrolyte:
The plates inside conventional batteries must always be submerged in acid. It’s therefore important to check the level of acid once a month and to add distilled water, if necessary. **Only applies to batteries that require watering maintenance **
Keep your battery charged between each use:
Batteries lose charge, even when not used. Some batteries can even lose 30% of their capacity in just one month. What’s more, batteries that are left discharged get damaged up until a point that they stop working.
In addition to charging your battery after using it, we recommend that you charge it once a month with a suitable charger or by leaving it connected to a smart charger between each use.
buying a charger
A charger is your battery’s best friend
Buying a DC battery without a charger would simply make no sense. Afterall, a charger ensures that your battery works properly.
A standard charger that allows you to chose different intensities according to the charging cycle you’re using.
Automatic chargers are the next step up from manual chargers: they charge batteries sequentially with multiple intensities. The best thing about them? You don’t have to do anything!
Latest generation charger that can evaluate the state of your battery during the charging cycles to ensure that your battery is charged in the best way possible. These chargers often come with a “maintenance” mode, which automatically keeps the battery charged when you store it away.
Ideally, you should use a charger that can charge at 10 % - 15 % of your battery’s capacity (Ah). A charger that is too strong, or not strong enough will affect the level of liquid inside the battery and cause problems in the long run. Some chargers come with different intensities of charge to make things simpler for you.
Depending on the type of technology your battery uses, a battery can be charged at more than 10 % of your battery’s capacity (Ah). This allows for faster charging.
Type of charger
There are three types of chargers available: manual, automatic and smart. Though smart chargers are as high-tech as you can get, automatic chargers are often less expensive.
We recommend you invest in a good smart charger. It will be of great service to you and will make your life simpler!
To ensure that your battery performs at its very best, we advise you to opt for a charger with an “equalization” mode. This mode allows the charger to try to restore the battery after poor maintenance or after several intensive discharges.
The “maintenance” mode allows the charger to manage the battery’s charge between each use. Generally speaking, the charger must be able to maintain at least 5% of your battery’s capacity (Ah). A smart charger with a “maintenance” mode and a charging capacity equal to 10 % of your battery’s capacity will enable you to enjoy the great outdoors, worry-free!
