New starting battery


fishinalot

Question

I'm buying a new battery for my 40 merc, I do run the d-finder and the livewell but not the trolling motor. Will a Marine starting battery keep up to the livewell and d-finder while I'm not running the motor for several hours? or am I better off buying the Deep Cycle/ starting battery?

The guy at NAPA said the starting marine battery is built to charge faster, but also is made to drain faster.

I'm replacing my battery because I fried my voltage regulator and I am replacing the battery that I had in it ( a Deep cycle/starting battery )

Thanks

Get the Deep cycle/Starting one. That way, if your trolling motor battery goes out, you could hook it to your Deep/Starting battery and not drain it way down. Since you are also hooking up your graph and livewell to your starter battery, it would not drain as fast if you had the dual purpose Deep Cycle/Starting type battery... would hold charge longer also.

The amount of time the battery will provide current depends on the load and on the amp-hours of the battery.

Regardless of the type of battery (starting, deep cycle, or starting/deep cycle) they will run the system for the same length of time if the load is the same and if the batteries have the same amp-hour rating.

The difference is that the starting battery innards will wear out faster if used in frequent discharge situations. Whereas frequent discharge situations are the forte of the "deep cycle" battery. The starting/deep cycle is between the two in this regard.

It would seem then that deep cycle would be optimum, but generally pure deep cycle batteries are not recommended to use as a starting battery. Not exactly sure of the technical reasons behind that.

Thanks for the responses. I did call a local marine mechanic and he told me that the starting battery is the better choice because the charging sysytem off the outboards are more sensitive and need a battery that will except the charge easier.

He said that the starting battery would loose the amps a little sooner, but would also charge the battery to a full charge quicker as well. He also told me that the D-finder and livewell would keep up fine.

So today I did pickup a marine starting battery and it does seem to turn the motor over much quicker (cranking power) then the Deep Cycle/ Starting battery did.

He also mentioned that it may have been the reason I fried the Voltage Regulator on the motor because that style(Deep Cycle/starting battery) does not except the charge as easy as the regular starting battery.

Well, we will see out it works out!

You should be just fine with a starting battery. I get 5-6 years on my starting batteries and I run my live well, electronics, and bilge pump on it and have never drained my battery.

Ditto.

Only this year did I have a starting problem - not really unexpected, I guess, with a 7-year-old starting battery. Mine also runs everything except the trolling motor.

      I'm not there, so I can't tell exactly what's going on but it looks like a large area of open water developed in the last day with all of the heavy snow on the east side of wake em up Narrows. These two photos are from my Ring Camera facing north towards Niles Point.  You can see what happened with all of snow that fell in the last three days, though the open water could have been wind driven. Hard to say. .

      Black Bay had great ice before but a few spots near rockpiles where there were spots of open water. It looks like the weight of the snow has created a little lake in the middle of the bay.

      On the south end...   Thanks to some cold spring weather, ice fishing continues strong for those still ice fishing.  The bite remains very good.  Most resorts have pulled their fish houses off for the year, however, some still have fish houses out and others are allowing ATV and side by sides.  Check social media or call ahead to your favorite resort for specifics. Reports this week for walleyes and saugers remain excellent.   A nice mix of jumbo perch, pike, eelpout, and an occasional crappie, tullibee or sturgeon being reported by anglers. Jigging one line and using a live minnow on the second line is the way to go.  Green, glow red, pink and gold were good colors this week.     Monster pike are on a tear!  Good number of pike, some reaching over 45 inches long, being caught using tip ups with live suckers or dead bait such as smelt and herring in 8 - 14' of water.   As always, work through a resort or outfitter for ice road conditions.  Safety first always. Fish houses are allowed on the ice through March 31st, the walleye / sauger season goes through April 14th and the pike season never ends. On the Rainy River...  The river is opened up along the Nelson Park boat ramp in Birchdale, the Frontier boat ramp and Vidas boat ramp.  This past week, much of the open water skimmed over with the single digit overnight temps.   Areas of the river have popped open again and with temps getting warmer, things are shaping up for the last stretch through the rest of the spring season, which continues through April 14th.   Very good numbers of walleyes are in the river.  Reports this week, even with fewer anglers, have been good.  When temps warm up and the sun shines, things will fire up again.   Jigs with brightly colored plastics or jigs with a frozen emerald shiner have been the desired bait on the river.  Don't overlook slow trolling crankbaits upstream as well.   Good reports of sturgeon being caught on the river as well.  Sturgeon put the feed bag on in the spring.  The bite has been very good.  Most are using a sturgeon rig with a circle hook loaded with crawlers or crawlers / frozen emerald shiners. Up at the NW Angle...  Ice fishing is winding down up at the Angle.  Walleyes, saugers, and a number of various species in the mix again this week.  The bite is still very good with good numbers of fish.  The one two punch of jigging one line and deadsticking the second line is working well.   Check with Angle resorts on transport options from Young's Bay.  Call ahead for ice road guidelines.

      With the drifting, kind of hard to tell for sure, but I'm guessing about a foot and still lightly snowing. Cook end!

      How much snow did you get on Vermilion? 
    • Mike89
      lake here refroze too...  started opening again yesterday with the wet snow and wind...  very little ice left today...
    • Hookmaster
      A friend who has a cabin between Alex and Fergus said the lake he's on refroze. He texted me a pic from March 12th when it was open and one from 23rd when it wasn't. 🤯

      I don't think that there has been any ice melt in the past few weeks on Vermilion. Things looked like a record and then Mother Nature swept in again.   I'll give my revised guess of April 21st

      As I get older it's really not just about sending bullets down range.  Some of it's just the workmanship of the gun and the wow factor. The other two guns I have really wanted which I'll never have now because of their price, is a 8mm Jap Nambu and 9mm German Luger.   Just thought they always looked cool!

      I had a guy hit me with a lightly used 1969 BAR, he wanted $1650 with an older Leupold scope. More than I think they are worth, I made an offer, he declined end of story.   You know if you look at the old brochures, a grade II BAR sold for $250 in the late 60s, $1650 would be a good return on your investment.    Why would anybody want a 50 year old gun, they are heavy, have wood stocks, and blued metal.  I guess mainly to keep their gun safes glued to the floor. lol   You can probably buy a stainless rifle that you never have to clean, with a synthetic stock you never have to refinish, is as light as a feather, and for half as much money, perfect.   I'm too old for a youth gun, although I've shrunk enough that it would probably fit. lol   No Ruger 10/44s.   Jim
