I have a 2000 70 HP Johnson (2-stroke) which charges it's own starting battery. I also have a deep cycle battery onboard which I use for a fishfinder and my electric trolling motor. I was looking at a device which I can hook up so my outboard charges my deep cycle battery.

First question: will the motor be able to charge the deep cycle battery?

Second: Is there anyone in the Ottawa area who sells these? I know Cabela's sells them but was hoping to buy one locally.

Cheers.

I can get you one but that will not solve your problem.

Your motor does not have enough constant amperage tpfully and completely charge your deep cycle and charging via your motor will only shorten the life of the battery. Buy a built in deep cycle charger and plug it in when you get home.

mikemicropterus,

Thanks for the info. I do have a deep cycle charger at home and if I go fishing for a day that works fine. The problem is when I'm gone for several days or weeks without access to electricity. In any case there's no point buying something that will try and charge my batteries of my outboard if it ain't gonna work. Any other options?

Pete

long extension cord or a generator, solar will not do it You could be onto a new invention, or have you ever seen a whispergen

This is not true by any means. I have been charging batteries from outboards for eight years now and have never heard of anything like this. Why would it take life away from your deep cycle?

I did a lot of googling a few years ago to try and learn the difference between Deep Cycle and crankers. The internal construction is very different and they need to be charged differently, Mike is right, you need a high current charger for deeps, and a lower current for cranks. Its due to the plate thickness. Deeps are design for a constant medium to high current draw and and require high current to prevent deposit build up on the plates. Cranks are designed for single very high current draws at engine start then a slow top up - consequently alternator voltage regulators match this requirement. And don't forget you need to top up the cranker which takes a while after starting, those pull cords are a pain.

Suggestions, if it's not every week, then the motor will probably be okay as a charge source but I wouldn't use it all the time. You can also get additives for the battery to help prevent deposit build up on the plates and extend your battery life and maybe negate the problem. Go see the experts, if I recall there's a guy at Total Battery that knows this stuff. Forget solar panels, they will take a week to recharge!!! Happy trolling

Here we go, I will try to contact the owner of this site before I jump in on this subject anymore. have a great day

oops. didn't mean to razz ya. If it has been working for you; great. Just saying there is a difference. If you look at most cheaper CT type battery chargers, there is a switch gving you the option of 10A or 2A. Deeps 10A, Cranks 2A.

No Razzing here, Charging from the outboard or tow vehicle if done the correct way will out perform any AC charger ever built. The way our systems work is that the batteries are not under any draw when we charge them and we only charge one battery at a time so each battery takes what it wants being 30 amps or 30 milliamps. We have proven this for the past 8 years and over 4000 units on the market today you can google or what ever you wish and you will not find anything out there that is a negative about Stayncharge products and as we all know if the were bad things about it then you would see it everywere. Not razzing you about your research either, You are correct about the AC units but when it comes to charging from a vehicle or the outboard there are ways to do it and batteries are charging faster and they are lasting longer as well. I always listen to what anglers have to say and that is how we built or units to be the way they are now, so thank you for your response and if we can help with making anyone understand how this is done please let us know. Thanks

With no disrespect intended, I disagree with the above statements. The ideal charging rate varies with battery type. I have a deep cycle Gel Cell battery. To maximize battery life, it should always be charged at low current levels (i.e. 2 amps). Gel Cell deep cycle batteries are better suited to applications where depth of discharge regularly exceeds 50 %. I use my Gel Cell deep cycle battery to provide power to my sonar unit for week long fishing trips (no access to recharging facilities).

Most Absorbed Glass Mat (AGM) type deep cycle batteries can be recharged at higher current levels (e.g. 10 amps). AGM type deep cycle batteries are better suited to high current draw applications.

I'm unaware of the ideal charging rate for flooded cell batteries. They must be recharged as soon as possible after use, and must be kept charged between trips. Leaving a flooded-cell battery discharged encourages life-shortening plate sulfation.

WHen charging anytype batteries from your alternator is copmpletly different from force feeding your batteries with the AC units. The batteries draw what they want and that is the bottom line. I have charged batteries for eight years this way and have never i mean never had a customer tell me there batteries did not last as long as they did before or has anyone ever been able to see any kind of heat that has caused damage. SO everyone has a opinion of things and that is great. Not getting into what he said she heard or any of that stuff. We have 90 day money back guarntee on all products and in eight years we have never been asked to return a unit for any reason. I hope this helps.

I'm not going to get into a pi^&^&sing macth over this but the question was outboard charging system and specifically a 2000 70 hp one that only produces 12 amps at 4000rpm.
Now if your product can charge PROPERLY under those conditions then I can see you getting a sale BUT you continue to refer to car alternator not 2000 70 hp Johnson.

I know my 200 Ficht can charge a deep cycle while I run the main engine because it produces 40 amps from the alternator and it does that at 2500rpm.

What I am failing to see is how your product can improve on an already fixed system and where would it miraculously find the extra current from a charging system that through physics can only produce 12 amps at 4000rpm.

However, I think your system more is suited for a car and or truck and I have seen them for a number of years especially in the RV industry where they are used quite extensively. I am not disputing that a 40 amp system current or more current on most cars will do a good job of charging depending on the time spent charging.

As stated earlier due to the construction and method of discharge how do you quickly recharge a deep cycle without warping the plates from too much heat which is the result of fast charging.

That's why a deep cycle has thin plates but a lot of them and starting batterries have thick plates and resist plate warping from high amperage chargers.

If there is something I missed in my 20 plus years of charging batteries,

Thanks for the input and we have been charging from 50 horse outboards for about eight years now. Please do not take this as a argument because our systems are not for everything for sure. I will not get into alot of tech stuff because most people only care about the bottom line and thats it. The unit is a computer chip controlled system. It monitors inout as well as output. The whole purpose of charging on the water is to give you that extra charge that you can get from running from one spot to the next during your day. 70 horse outboards are not going to charge from dead to full if you have been on the trolling motor all day and only run 15 or 20 minutes to the dock and that is not what we say it will. As far as you charging for 20 yrs, You have not been charging from a tow vehicle or an outboard and we have. That is why i have a full 90 day money back guarantee on the units just for people can try them and if they don't do what we say they do we would be more then happy to refund there full prize including shipping without any problems. In the past eight years and 4000 units on the market we have never refunded anyones money for any reason. So as far as all the talk we have put the proof in the pudding. Thanks

Now I realise you are pushing a product here, I went to look at your site. I see that you have some smart gizmo that controls the voltage during a charge, this was missing from previous posts where I assumed a direct connect to the alternator, which would be bad for a DS. Do your products use a 3 stage charge profile, it doesn't say on the site anywhere???

Tomcat, agree with your statement, all batteries are differrent, I'm a little old school with flooded cell - don't know much about them there new fangled Gel types. I use a 3 stage on board charger which I plug in when I get home.

First off I am not trying to sell our products here(yet until I talk to the board owner). I am trying to educate people on how they work. Old school is great to me. I started charging my first trolling battery 30 years ago from a truck. As far as stage charging no we do not. Our All Charge unit is a computer chip controlled switching box. And yes it moniters batteries. The big thing about charging from your truck or your outboard is when we are charging the batteries are not under load so when it is time for them to charge they take what they want, we do not force feed them at all. And as far as generating heat to them that is what I will hear the most negatives from people that have not tried it. You can pull your boat from Los Angles to Florida with our system hooked up and you can get out touch either the wires going to the unit or even touch the unit and they both will be as cool as they were when you took off. We also have customers that were going to buy new batteries before they installed our system and I asked them to wait and see what happens after they use the units. They are still using the batteries they were going to replace a year ago. So all the talk and smart peoples opinions the bottom line is still,,,the proof is in the pudding. If there is business here for us we will still go through the site owner before we take it. Thanks
