FishFinder Battery

12 posts in this topic

What is the best battery to use for a Humminbird 300 TX? Should you use a marine starting or Deep Cycle? Thanks!

Either battery will work fine for powering your Humminbird. The only problem you might run into, would be if the output from your motor's alternator goes higher than about 14.6v, it will cause the sonar to shut off. But that is not very common.

Either battery will work fine. The current draw form any sonar is low enough that you will get many trips before you will need to recharge your battery and you will probably never significantly discharge it.

The difference between starting and deep cycle batteries is that a "deep cycle" battery is designed internally to provide a steady medium current output and be able to be completely discharged and subsequently recharged. It's plates are designed with adequate spacing to handle this discharge/charge cycle without damage.

A starting battery is designed to provide short bursts of very high current and be kept under continuous charging by the engine's alternator. This prevents the deep discharge/recharge cycle from occurring. The starting battery has plates closely spaced to provide maximum current capability in a small space, but this design cannot withstand deep discharge cycles.

What eventually kills the battery is that every time it goes through the discharge/charge cycle, the plates slough off some material, eventually plugging up the space between themselves.

How do the "dual purpose" deep cycle/starting batteries stack up?? I have 3 of this kind, that I also run the trolling motor and graphs off of.So far, I have not been seeing any problems.

OK D-man, I'll bite. Now, I'm not trying to be a smart a$$ here. But, since it is obvious that many of us are running our locators off of our starting battery without problems, why are you so against it. I know it would be bad if you were to runn the battery completely dead, but as long as the charging system keeps up the battery, I don't see a problem.

Again, no offense meant here, I just want to know WHY before my boat explodes or something.

I've got a couple of the dual purpose batteries too. I've always wondered if its just a marketing gimmick. But I don't really know and like to find out.

I ran my LMS350 off my starting battery all year with no apparant battery problems. But the electronics do drain it down, leaving me vulnerable to starting problems. So, I am installing a deep cycle battery dedicated to running electronics. I'm a firm believer in deep cycle batteies now for those low current long draw applications like the depth finders.

Trial and error and personal experience. I dont understand why boat dealers wire accesories to a starting battery? I dont think there is any danger or concern for expolsion. If you have the room, its better to add a second deep cycle. You can certainly use accesories on a starting battery but the life of the battery will deteriorate and when you go start the motor someday and nothing happends,just make sure your pull cord is in good condition.Hydro's post explained it well.Also you need to remember that most mid-range motors put out 6-8 return charging amps.Bigger v-4's and v-6's put out over 10amps. But these return charging amps are at max running RPM's.

The exact problems I've had running the electronics off the starting battery is this: the electronics drain it down. If it's night, the running lights also come off the starting battery, as does the live well pump and bilge pump. If after fishing for an hour or so, the motor cranks over slow, the fishfinder turns itself off on low voltage, and I hope my 120 hp. Force actually does start. I bought a small starting battery for about $40 last year. Might have been wise to spend another $20 but since I also need a trolling motor back up battery, the obvious solution for me is to buy a deep cycle battery and take a load off the starting battery.

    •   Anything you post on here from now on has no merit or credibility as far as I'm  concerned.  I wasn't even going to respond to this, but feel what you posted needed to be. If you wish to call my mother a dam, you will, the same as you called another persons mother that. I don't give a rats butt what your political views are, however when you start getting into personal attacks you had better look in a mirror. You don't probably don't know anyone on here personally, yet you attack someone on a personal bases, call there mother a dam and ridicule them because they had a lower portion of a leg amputated due to something they can control, but had no control whether they have the illness and sometime that illness makes you pay a price. BD2 has that illness he can control to a certain extent where he can lead a normal life, however there will be complications and from what I know of him he will accept that. I don't know DB2 personally, I've never met him, I've debated against some thing on this where he and I have had different views, I respect his opinions even though I disagree on many, BUT I SURE AS H--- DON"T ATTACK HIS ANCESTORY OR  ANY TYPE OF DISABILLITY

    • Great to see this in Minnesota. Trout has been on my bucket list and will happen this year. The mix of largies and smalls really works for this show and plays into the guys heads. I was pulling for Hack. He's become one of my favorites. I think these guys are gaining a new appreciation for MN.  Except maybe the Lane Bros.
