New starting battery

6 posts in this topic

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.

      The Department of Natural Resources designated the state’s third groundwater management area this week. The Straight River Groundwater Management Area in northwestern Minnesota includes parts of southern Clearwater, northeast Becker, southwest Hubbard and northwest Wadena counties. Cities within the boundary include Park Rapids, Osage and Ponsford.  In addition to the designation, the DNR approved a management plan for it. The plan lays out five objectives with specific actions the DNR will take to ensure that use of groundwater remains sustainable within the area. The plan was developed over several years with the help of an internal DNR project team, an advisory team of external stakeholders, and additional public review and discussion. “With more than 10,000 lakes, thousands of miles of rivers and streams, and many thousands of acres of wetlands, it might be natural to think that our water is essentially unlimited,” said DNR Commissioner Tom Landwehr. “But in some parts of the state, the unseen, underground aquifers that make up our groundwater resources are under pressure to meet growing needs for domestic water supplies, irrigation, industrial and other uses. These groundwater resources also are interconnected with lakes, streams and wetlands that we value for commerce, recreation, and water supplies. Those surface waters also provide the habitat needed by many animals and plants. If we are not careful in how we use water, both economic development and ecosystems could be put at risk.” The plan provides a framework within which the DNR will work with major water users, including municipalities and agricultural irrigators, to use groundwater sustainably. This cooperative effort will promote conservation, protect surface waters and water quality, improve the groundwater appropriations permitting process, and help resolve any conflicts that might arise among users. This is one of three groundwater management areas being established around Minnesota. The other two are in the north and east metropolitan area and in the Bonanza Valley near Paynesville in west-central Minnesota. More information, including plans and maps for the Straight River Groundwater Management Area, can be found at on the management area webpage. Discuss below - to view set the hook here.

        Yes and going to the game on Sat.  Good thing I didn't buy the tickets!  Lol

      I've never herd of any tullibee being caught from open water. Doesn't mean it's not possible but I'm not going to say you can go out and slay em. Hopefully others chime in and answer you question with certainty.

      I would say it's fine. M-MH are very good for many things just need to be careful when throwing things heavy if it's close to the max lure weight. That's when bad things happen. Didn't really answer your question but hope that helps.

      Ok wanted to try fishing Tulibee icefishing but just have run out of time, my question is it possible to fish them in the summer? And the best way to do it? Thanks!!!!
