How Do You Charge Your Trolling Motor Battery Using the Outboard Motor?
How does a trolling motor recharge?
Once the outboard is running, its alternator will recharge the cranking battery to compensate for the power delivered while starting the motor, and for any power drawn for other “house” needs, including live well or bilge pumps, fish finders, or navigation lights.
Do trolling motors have alternators?
Yes. Almost all outboards that have electric start and that were built in the last 20 years, will have either an alternator or a stater that charges the battery when the engine is running. At what capacities and loads they charge the batteries is another thing.
How long will a trolling motor battery last?
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.
Can you charge a deep cycle battery with a trickle charger?
Trickle charging is the correct way to charge a deep cycle battery.
How often should I 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.
Is it better to charge a deep cycle battery slow or fast?
A deep cycle battery is not designed to handle the rapid charging and extra heat, so it may never reach 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.
Can you overcharge a deep cycle battery?
Can you overcharge a deep cycle battery? Yes, the deep cycle batteries can be overcharged. … On top of that, the charger that you are using to charge the batteries and the charging method being used to charge the batteries speaks a lot about the overcharging of the deep cycle batteries.
Should I charge my battery at 2 or 10 amps?
Consequently, when trying to charge a larger battery at that rate, it will take a very long time and the battery may discharge at a greater rate than the 2-amp charge can provide. It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher.
Do I need a special charger for deep cycle battery?
Deep cycle batteries provide a controlled flow of power so that it remains active for a significantly longer period of time. To charge these batteries, you will need a special type of battery charger called a deep cycle battery charger.
How fast can you charge a deep cycle battery?
A charger with 15 amps, for instance, will take about two hours to fully charge a battery at a 25-percent discharge value. Chargers with only 5 amps, however, will need a full six hours with the same battery.
