A dual-purpose battery provides enough power to start the engine and turn it over, while also providing enough energy to keep your trolling motor running consistently. As the name implies, dual-purpose batteries can be used for both purposes. … They will provide exceptional performance when used with a trolling motor.
Can you use any battery for a trolling motor?
Boaters use a deep-cycle marine battery to start and run outboard motors or to power a trolling motor. Any deep-cycle battery will power a trolling motor, but a marine battery tends to be built tougher for use on a boat.
Should I use a dual purpose marine battery?
Dual purpose batteries are ideal for applications that require starting and deep cycle service. They deliver powerful cranking amperage for easy starting, and low amp draw service for reliable auxiliary power.
What is the difference between a deep cycle and a dual purpose battery?
For instance, deep cycle batteries are built to withstand many discharges and recharges while cranking batteries are not. A dual purpose battery, therefore, falls somewhere in between. Many do not stand up well to total discharges (discharge beyond 50% of usable capacity).
What is the difference between a starting battery and a dual purpose battery?
AGM dual purpose batteries offer many unbeatable advantages over conventional batteries, and some of the key differences are outlined below. … More starts per battery, up to three times longer battery life. Low self-discharge rate. Recharges up to five times faster.
Can you use any 12V battery on trolling motor?
A regular car battery will work it just won’t work for as long as a deep cycle battery would. Yes you can, but the battery won’t last. Regular cranking battery such as those used in automobiles are not designed to be completely discharged and recharged(they’re design to be topped off).
Are all AGM marine batteries dual purpose?
AGM Only – Most dual purpose marine batteries are the sealed AGM style. Many Lead Acid marine batteries simply cannot provide the necessary CCA and deep cycling ability needed for large motors and electronics. … Make sure the charger for your boat has AGM charging capability.
How long does a dual purpose battery last?
Here’s exactly how… How Long Do Boat Batteries Last? Most marine batteries last anywhere from 2 to 5 years depending on the level of care you give them.
How do you charge a Marine Dual Purpose battery?
Make sure your 12-volt constant current charger is turned off. Hook up the negative, black terminal to the negative side and the red, positive terminal to the positive side. Your first phase of charging is termed bulk, where you maintain constant charger amperage and your battery’s voltage increases.
What is a dual purpose deep cycle battery?
Marine Dual-Purpose Batteries combine the performance of starting and deep cycle battery, and are a good choice on smaller when there’s no room for two batteries. While they’re able to perform the tasks of a starting battery and deep cycle battery, they’re not as efficient as separate batteries.
Can you start a boat with a deep cycle battery?
Can You Use a Deep Cycle Battery For Starting? The short answer is that you can probably use your deep cycle battery to start your boat engine in a pinch. You shouldn’t rely on your deep cycle battery to start your boat engine all of the time because it isn’t designed to do that.
Can I run a deep cycle battery and a starting battery in parallel?
Almost any other type, and especially Lithium-based batteries, it’s a total no-no. If there is any discrepancy in the voltage between one cell and another, if they’re placed in parallel the higher voltage will push current backwards into the lower voltage cell.
Can you use a dual purpose battery in a car?
So, yes. A marine battery can replace a car battery if it meets the requirements about voltage, CCA rate, size, and terminal positions: Is a 12V battery that is recharged by the alternator. Meets the high CCA rate requirements of 650 CCA, or even 800 CCA for cranking the engine.
What is an AGM battery?
AGM or Absorbent Glass Mat is an advanced lead-acid battery that provides superior power to support the higher electrical demands of today’s vehicles and start-stop applications. AGM batteries are extremely resistant to vibration, are totally sealed, nonspillable and maintenance-free.
What are starting batteries designed for?
A starter battery is designed to provide a large burst of current for a short period of time. This surge of current turns the engine over during the starting process then the alternator takes over. The burst of energy only discharges the battery 1- 3% then is topped off by the alternator.
