Deep Cycle vs. Trolling Batteries
What is the difference between a Deep Cycle battery and a Trolling
battery? I'm buying a Minn Kota Endura 30 electric trolling motor and can't decide on the battery. Even the salesman gives an unsure answer as to the difference between the two. Which one do I buy??? -KCB |

Deep Cycle vs. Trolling Batteries
A trolling battery is a deep cycle battery with built-in extra boat
dealer profit........like any part you put "boat" labels on. Buy a deep cycle battery from a BATTERY store and save the extra markup.... Put 4 golf cart 6V batteries in series (255AH for $69 at Batteries Plus) and run it on 24V if it's rated for 24V. Works great if you can leave the batteries in the boat permanently. Great ballast to hold the bow down in the waves, too!....(c; On 20 Aug 2003 00:50:01 -0700, (kcb559) wrote: What is the difference between a Deep Cycle battery and a Trolling battery?

Buy a deep cycle battery from a BATTERY store and save the extra markup.... Good idea! I get my batteries from Polar Batteries here in Vanc. They get Trojans and put their own label on, they're cheaper than Canadian Tire. Put 4 golf cart 6V batteries in series (255AH for $69 at Batteries Plus) and run it on 24V if it's rated for 24V. Works great if you can leave the batteries in the boat permanently. Whoa! He's talking about a Minn Kota 30, here! First, it's 12V. And second, it takes maybe 30A at full load. I use a Group 22NF battery ($49.95 at Canadian Tire) and it runs pretty much all afternoon. I'd say a Group 24 deep cycle would be fine.

What you want is a deep cycle battery that is specifically designed for trolling. Otherwise your motor will run like a rabbit for about 30 minutes and then taper off quickly. Actually, the motor will run identically between deepcyle/trolling and starting. The difference is, the 4th or 5th time you run the battery down to "dead", the starting battery won't come back up, but the deepcyle will. The 22NF battery I use on my Endura 30 is a "starting" battery, and it runs the motor fine. I just don't let it run down to more than maybe 50%. I still expect it to not last that long, but it's on it's 3rd year now... (It was a "Proof of Concept" purchase: I wanted the cheapest I could buy in case it didn't work out.) Lloyd Lloyd |

The difference between a start battery and a deep cycle battery is that the starting battery has thinner plates allowing for initial high amp discharge, but have zero capacity for long term discharge.

Sorry Lloyd, but you are incorrect on that point. Why? Does the deep cycle have different volts? Ohms law doesn't apply? Same volts, but a different power output curve. The starter battery is designed to output maximum amps for a short period. The trolling motor will gladly use whatever is available, and the starter battery will quickly lose output if you run the electric motor at full speed. The trolling motor will run like a jackrabbit for a short time, and then will lose it's enthusiasm. A deep cycle trolling motor will output lower amperage over a longer period. Think of the difference between a sprinter and a marathoner. That's why there are many different types of batteries. Different uses require different characteristics. BB There's a difference between how much current a battery CAN supply and how much the load is drawing. A 30-lb Endura pulls 30A at 12.5 V (approx) full load. It's Ohm's Law, not the battery characteristics, that determines the current. A fully charged battery, starting or deep-cycle, provides this: 30A is not excessive even for a deep-cycle. The discharge curves are slightly different, so the voltage drops differently between the two, but not enough to notice. As I said, the difference in this case is the ability to "come back" from a deep discharge. If we were talking about 200A, you'd be right. I've been running the exact motor he's talking about with a small starting battery and have not seen what you describe: it just slowly runs slower as the battery dies, over the course of several hours.

It STILL won't last as long as a deep-cycle, but I've been doing that for 3 yrs now and the battery still works. One other thing: a "deep discharge" on a starting battery will reduce it's capacity much more than it will for a deep-cycle. Ie. you run a starting battery dead once, and it will have maybe 50 A-H capacity rather than the 80 it had before. Spend the extra $20 and get the deep-cycle. Lloyd |

The Maximizer gives full voltage to the motor at all times via a pulsed DC and reducing the duty cycle vs. the other motors give a reduced voltage via a resistor to slow the motor down. The resistor burns up energy as heat, therefore less time from the same battery. The pulsed DC has an effective voltage less than the 12V's but the reduced voltage is not wasted as heat. If you want all the numbers and formulas, I could probably go through my college stuff and dig up my senior thesis where I disigned and built an underwater dive light with an intensity control via a 555 timer and same principals.

Deep Cycle vs. Trolling Batteries
Wrong, Chuck. The starting batteries can supply more current over a shorter
time. Total amp hours can be the same. Those thinner / more surface area plates allow the high current loads. Is the main difference between starting and deep cycle. Bill Only partially right, Bill. If you compare small, cheap, batteries it's true. Going up a size with a deep cycle delivers more than enough power to start an engine. What aspect of electricity do you maintain can only be adequately supplied by a battery with a "starting" sticker on the case? Amps? Volts? The top rated battery companies don't even offer "starting" batteries in 12 volt sizes. (They do offer 8 volt starting batteries for wiring up 24 and 32-volt combos for cranking monster engines) Check it out. http://www.dcbattery.com/rolls.html |
Deep Cycle vs. Trolling Batteries
Completely right. The non-small, non-cheap batteries, are not even rated as
a starting battery. Is just a very big source of electrons. An 8D etc. are different than what most batteries you find in most boats. Most boats are not 30'+ cruisers, they are O/B and I/O powered runabouts. No house bank, but on a bass boat a couple of deep cycle batteries for the trolling motor and a big starting / deepcycle (group 27) for starting and running the livewell. And these are very susceptible to the different current loads. An 8D / 6D is called upon to supply power for 1kw microwaves during anchor time. Therefore they are required to be large current sources i.e. Low internal resistance. But they also may weigh 200#, as opposed to the 40# for most batteries in those runabouts.
