Battery questions.

[Fixxxer93]

Acouple questions about batteries.

1.I have two deep cycle batteries, and need to add a third cause I have a 12/24 trolling motor, should I get a cranking battery and only use it for the motor, or a different one to run my electronics off it to?

2.I have a battery that came with my new to me boat but the previous owner said it wasn't good, but I fully charged it and used it for 6 hrs using it on the 12v side of the trolling motor. Seemed to me to be good, how do you check it? (weird question I know)

3. My trolling motor is set up where it has two hot and two grounds, do I need to change it to where the batterys are in sequence? emoScratch

1) Get a cranking battery to start your motor and run your electronics.

2) If you don't have a battery tester or hydrometer, charge the battery and get it load tested. Autozone will do it for you.

3) The trolling motor batteries are fine they way they are connected.

It's holding at about 12.3v for a week now, with no load of course. I think it's going to be fine, just needs some water. I appreciate your reply.

After going over everything I noticed my trolling motor is just a 12v. Is it still alright to use two batterys for the trolling motor if it has two positive lines and two neg going up front?

Disconnect one of the trolling motor batteries.

24 volts will burn the 12 volt trolling motor up.

Trolling motors aren't cheap anymore.

I'm alright, I only have one battery right now, but was thinking of adding a battery, but I guess I can use it for electronics ect. I thought tho I read once that if it had two + and two= that you were ok, its only 24v when you put them in sequence. Correct me if I'm wrong cause I don't want to mess it up lol

You can hook up two batteries on a 12V motor. You need two jumper wires. Simply connect the positive+ to positive on both batteries and connect the negative- to the other battery negative and you will still have 12V. This would be a parralell connection and you will double the battery life. Trust me a trolling motor wont last long on a single battery.

You corrected me, Thank you. I couldn't remember which way to hook them up to make it more "efficient". emoThumbsup

I run Three (3) Dual Purpose batteries. They serve the purpose for both Trolling and for Cranking. My thinking is that if ever I have a starting battery issue while on the water, I can simply switch out one of my TM batteries to get home. I have Never ran down my trolling batteries and I do mean from continuous use for several days. I go Off-shore, therefore I do want to get home.</p>

In many cases a Trolling only battery will NOT Turn a Cold Big Engine fast enough to crank it. I know.. "Been there done that." At 3:00am with ice covering my deck I had to troll a mile back to CF Park. Then load without power. Bad Day/night on the water.</p>

I'm running a deep cycle battery now and seems to be doing fine. When I first got the boat it was real hard to start but the battery held up. It's cranking fine now and the trolling battery seems to be holding its own too. They are both deep-cycle, but was wondering if I add a 3rd what it should have been, so I'll take your advice, thanks.

Iassureyou a cold big engine will not start with a deep cycle if you have anyfloodingor fuel issues. I used to do what most people do ... I had two deep cycles for 24 Volts to the TM and a very good quality Marine starting battery for the engine and accessories.</p>

Having a moment of stupid here lol, but what do you mean by duel purpose? Your not talking about deepcycle/cranking are you? Sorry about the question but just want the best for all situations. I know the one on my motor is a 650 cca, but also deepcycle, is that what you mean? emoScratch


Ok to kill this thread so I don't keep dragging it on , what brand ect do you recommend, and where do you buy yours at? I've got a 1986 Mariner on a !986 Astro-glass w/ a Minn-Kota 12v trolling motor. emoBigsmile

 

[Liveliner]

A duel purpose is like a Hybrid of the best of both. Supposedly it will not troll for the total hours that a deep cycle does, But I have trolled of hours for several days and could not detect weakening power. They were still near full charge when I checked.
I use the big 29 Series Duel Purpose batteries from Walmart. Their yellow ones. By comparison they are about half the price of the Popular Marine Batteries that many favor. The way I see it the all have a limited life so I think buying half price allows me to buy a replacement and actually get more life for the same money. Mine are about three years old and I think one is over four years old. I can not complain.
I do not want to start a battery debate here..

Thanks for clearing it up for me it's like anything that you buy, I might buy it and it work longer than yours so you hate it. I asked your suggestion and you helped, so thanks.
