1033.0. "Info wanted on battery for trolling motor" by JHNTHN::SAREN () Thu Mar 16 1989 10:02

    I recently acquired a trolling motor.  Unfortunately it did not
    come with a battery. 
    
    Should I go to Sears and buy the Marine battery or would a any 12
    volt do the trick?
    
    Assistance would be appreicated.

   Buy a DEEP CYCLE battery.  The standard auto battery does not like being
charged and discharged very often.  Where you might get 15 or 20 
charge/discharge cycles out of a standard battery, you should get over 100
out of the deep cycle battery.  The auto battery is designed for a high
current discharge over a short period of time (i.e. cranking an engine over
when it's cold) whereas the deep cycle is designed to provide much less
current, but to discharge over a long periood of time...

   For the price difference, but the one built for the job...

1033.2Where does one find DEEP CYCLEJHNTHN::SARENThu Mar 16 1989 10:383
    AL,
    	Please,  is DEEP CYCLE a brand name?  Or is it a model? Can
    I get one anywhere?

                 I believe K-Mart sells Delco Voyager batteries.
    Don't know the price but they are a good battery.

    I grabbed a pamphlet from the "Delco" display at K Mart, they rate
    the Voyager to out last the closest competition by 2,455 "AMP" hours.
    Everyone seems to run these and they are a good value, I personally
    have one to.

    SEARS has a deep cycle battery for marine use. This battery has
    been reduced from 90 dollars to 54 dollars... every single day!!!

I have two DieHard marine deep-cycle batteries. One is going into its fifth
season, the other into its sixth. 

I feed them distilled water and the proper charge rate i.e. 10 amps then trickle
at 16 3/4 volts.

    I have just purchased a Sigma(Shakespeare) 25lb thrust trolling
    motor.
    It will only be pushing a 12ft light weight Flat Bottom John-Boat.
    
    I am now ready to purchase a battery and battery charger.
    
    Looking for responses to How Many amps.
    
    I've seen Marine trolling batteries from 520amps to 720amps.
    And chargers from 5amp to 10 amps.
    
    I would like to be able to run the engine for at least a 3-4 hours
    maximum at variable speeds.
    
    Any advice???????
    
    Thanks in advance 
    Tony
       
1033.13A simple formulaVICKI::DODIERThu Apr 20 1989 14:0518
    re:12
    
    	The 500+ amp ratings are for what is called cold cranking amps.
    This is the power available for a short amount of time to start a gas 
    engine.
    
    	What you want to look at is the amp hour rating of the battery
    and the draw of the trolling motor and that will tell you approx. how 
    long a given battery will last on a given motor. 
    
    	Let's say for easy figuring you got a 120 amp hr. battery and the
    max. draw on the trolling motor was 30 amps at full throttle. You
    would get approx. 4 hours use out of the battery before it needed
    to be recharged.
    
    		i.e. 30 amps x 4 hrs. = 120 amp hrs.

       Mac, I have the same motor you do. I bought a Sears Die Hard
    on sale, forget which one, I'll check tonight. I think it was a
    smaller one though.
     I haven't come closeto wearing it down. 
     I also bought the Sears 2-10-50 Amp charger on sale. I like this
    one because if you have a dead car and nothing to jump it with the
    50 Amp setting will start it up.

1033.15auto shutoff charger is a must!!HPSCAD::BPUISHYSBob PuishysMon Apr 24 1989 09:3511
    4 hours on full draw is not much on a day like yesterday!!!
    
    I have two AC-DELCO deep cycles.  After an eight hour tournament
    yesterday they were down below 25%. Even with a 24volt trolling motor
    it was hard holding in the wind when they get that low!
    
    Get a deep cycle and a charger that has two features:  auto shutoff,
    and a switch to trickle charge..

1033.16Holding a charge in storageCASV01::PRESTONBetter AI than none at allWed Apr 26 1989 10:4111
    Anybody know if a 4 amp charger can overcharge a deep cycle battery?
    Also, has anybody noticed what sort of charge usually remains after
    sitting in the basement for the winter? My one-year-old Die Hard,
    according to my $.99 hygrometer, is down to � charge. Is that unusual?
    
    (I put my battery on a piece of carpeting to keep it off the concrete,
    BTW)
    
    Thanks,

1033.17a 4 amp charger could over charge if left on long enoughHPSCAD::BPUISHYSBob PuishysWed Apr 26 1989 11:236
    I left my batteries in the boat all winter..  the deep cycle
    did not even need a charge,  the acid water battery was down to
    50% (year before the acid water was almost dead.)

1033.18Re:16 Sounds about rightVICKI::DODIERWed Apr 26 1989 11:265
    	That happened the first year I had mine (placed it on a piece
    of wood to get it off concrete). Now I charge mine at least once
    or twice over the winter months.

1033.192 questions?CLUSTA::FAUCHERThu Jul 13 1989 10:0532
    
     I have a question:
    
     Typically, what is the amperage of a decent trolling deep cycle
     battery?
    
     The reason I ask this is because I have a acquired from a friend
     a brand new 55 amp Deep Cycle battery (I have a shakespeare 20 lb.
     thrust trolling motor for a 10' John boat).  I have been reading 
     the previous replies and have noted folks mentioning 80+ amp
     deep cycle trolling batteries...
    
     I have used this battery only twice so far and it seems to have
     held a charge decently (but twice is NOT a very good test 
     obviously).
    
     So, if someone could tell me if a 55 seems to be decent, then I will
     stick with it, but an 80 amp sounds so much better, sounds like
     it would move the boat somewhat quicker, is this the case?
    
     Also, this battery I have is sealed and has no indicator eye... 
     any ideas on a good way to tell if it is fully charged?
    
     Right now (twice) I have let it charge until it has felt warm (not
     a good way I know... but the only way at the time).
    
     Thanks for any help.
    
                                                Perry F.

1033.21Same Speed, More RangeEDRON1::DOTYRuss Doty, CTCThu Jul 13 1989 18:1711
    Amp hour rating is how long the battery will last.  All batteries
    will drive the electric trolling motor at full speed -- when fully
    charged.  The difference is in HOW LONG the battery will drive the
    motor at full speed.  The bigger the battery, the more hours.
    
    So, a big battery won't move you any faster -- but it will move
    you farther!
    
    (To get full speed out of the trolling motor, run BIG wire from
    the battery to the motor.  I used 6 gauge jumper cables to wire
    mine...)
