The higher the number, the faster they will recharge. A 5 amp charger will re-charge mid-range batteries fully in 10-12 hours and should be fine for most fishermen. But if you need lightning fast recharges, or if you have batteries that are 120 amp hours or higher, we recommend purchasing a 10 or 15 amp charger.

How often do I need to charge my trolling motor battery?
Maximizing Battery Life
- Battery and boat manufacturers recommend that you fully recharge your trolling motor battery as soon as possible after use.
- It’s a good idea to use a trickle charger during the offseason to keep power flowing through the battery, or to re-charge them every month.
Can you overcharge a trolling motor battery?
Overcharging and Undercharging Marine Batteries
Neither are good,” says Dan Baston, Product Manager / Lead Engineer at Minn Kota. Over or undercharging your batteries will shorten their overall life. Minn Kota chargers are digitally designed to deliver just the right amount of juice every time you plug in. No more.
How long does a 12 volt battery last on a trolling motor?
In more technical terms, a 100 amp hour rated battery can deliver 100 amp hours of current to a trolling motor. So if a motor was running at low speed and pulling 4 amps, the battery should last around 25 hours.
How long does it take to fully charge a boat battery?
It usually takes around 4-6 hours
In most cases, a marine battery will take around 4-6 hours to charge. This will bring your battery from 0% charged to 80% charged. In addition, it depends on the type of charger that you’re using.
Is it better to charge a deep cycle battery slow or fast?
Instead, it will show that it is fully charged long before it actually reaches full capacity. By contrast, a slow charge is perfect for charging deep cycle batteries because it prevents heat from building up and ensures that the full capacity of the battery is reached.
How long will a marine battery run a trolling motor?
Almost 5 hours doesn’t seem too bad, but that is really a max runtime in ideal conditions. Reality is likely to be less. If the battery is old, damaged or not fully charged then you will not get the rated amp hours from it, reducing your runtime. Significant cold or hot weather will also reduce your runtime.
Should you trickle charge a deep cycle battery?
Batteries will self-discharge over a period of months even without a load. Many GEL, AGM and Calcium’s are better than regular lead-acid batteries but even so you should charge them back up regularly, or better still use a trickle charger (or solar panel) to keep them in top condition and extend their life.
How many years does a trolling motor battery last?
Lead-acid wet cell batteries are one of the most common types of batteries to use with trolling motors. They are an affordable option that can handle the everyday uses of a trolling motor. They typically last around 2-3 years and may require some sort of maintenance.
Should I leave my boat battery charger on all the time?
Since there is no usage, it doesn’t really make sense to keep your battery and charger plugged in all of the time. On the flip side, if you keep your boat stored in the water, you’ll probably want to have access to your charger readily available because you will need the bilge pumps on your boat working.
Can you charge a boat battery while connected?
Jetboaters Admiral. No need to disconnect the batteries. If you have a battery switch, turn it off, if not, don’t worry about it. A word of caution, if you run the battery down playing music or with lights for hours, the charging system on the boat will not bring the battery back up sufficiently in a short boat ride.

How long will a 24v trolling motor run?
This will give you maximum speed and power and is often necessary on a large boat, or in strong winds. Thus, if you operate your trolling motor at maximum speed, you will typically get about 2 hours of use from a fully charged pair of “average” batteries. Possibly 4 hours of use for the larger extra capacity batteries.
Is it OK to fast charge a deep cycle battery?
It is fine for flooded-style batteries. But fast charging may shorten the life of your AGM or GEL battery, and it’s not recommended. The other problem is that the high charge rate will cause heat inside the battery. This can prevent it from reaching a 100% charged condition.
How do you tell if a deep cycle battery is fully charged?
A full recharge should see a maximum temperature rise of 10 degrees Celsius. Once the battery is fully charged it can be maintained by applying a charging voltage of 2.24 to 2.25 volts per cell (13.4-13.5 for 12volt and 26.8 to 27.0 for 24volt). This is called a “Float” charge.
How long does it take to charge a deep cycle battery with a generator?
If the generator is plugged into an AC outlet, it can take up to 2 hours for the battery to fully charge. It will take longer if your RV battery is below 20%.
Do marine batteries need a special charger?
Do Marine Batteries Need a Special Charger? No, the main thing you’ll want to look for is that the charger matches the voltage and chemistry of your boat battery.
