Battery question

[Old Mud]

I need some advice, I am using a group 24 starting battery for my starting and running my electronics and a group 27 deep cycle for my house and hauler . (only used when hauling my anchor). I Tuna fish hooking and while sitting on anchor after 8 or 9 hours with my sounder on (Sitex 600 watt) my group 24 is nearly dead. Have tried a deep cycle here in the past but with about the same results so ill have to live with that.

I have a generator that I run at night for lights and charging. I am going to replace it with a group 27 and don't know whether to buy a Deep cycle or Starting batt. As I run this batt down every day is it better to have a deep cycle ?

Thanks

Don

I would go with a deep cell which should last longer than a starting battery. Why not run the gen set for 30 minutes during the day to top off the batteries?

How about a 4D? Or put a couple of 24's in parallel?

Is it a space requirement? Or a weight requirement? Maybe a solar panel or two could help out?

 

[djmarchand]

If you use a deep cycle for both starting and electronics and then run it down, it may worsen the problem and not start. Starting batteries can supply a lot of current when down, deep cycle batteries cannot.

One solution is to double the capacity, either 2 Group 27s in parallel or one 8D. A better solution is to power your electronics from the house battery which should be a deep cycle and parallel with another battery if necessary.

That seems like a lot of drain for just having the sounder on. And I'd think the deep cycle would be the way to go. Have you ever tried switching to your other battery mid-day?

Thanks for all the info, To answer your questions,
JK porter, I sometimes run my genny during the day but guess I was looking for a simpler solution. I use a Honda EU 2000 and it sets on my engine box, (outdrive) but I like to have the box clear so I can throw the harpoon basket up there when needed.

Travis, Yeah, it's about weight And space oh and I do have a Solar panel but it's only 15 watt, 1 Amp. Just enough to keep my batts. topped off when she's sitting at the mooring.

Dave, yeah I thought about going to more amperage but as I said. Space and weight comes into play.

Bill, yes it is a lot of drain. guess I didn't give all the info. out. I also run 2 vhf's, a chum chucker, radar on standby when foggy etc. both my Radar and sounder are CTR. My plotter/sounder is digital but I don't like it on sounder mode because it doesn't have as good a signal and more than that no dedicated keys like my Sitex. Oh and yes I have tried switching my batts. mid day but I have to have All that amperage when I use my hauler (Electra-Dyne).

Thanks again think ill go get a 27 starting batt. and live with that.

You might want to call an electronics shop and run it by them. Seems like they could give you some insight as to whether the combined draw adds up to the drain you're experiencing. If not maybe there's a short or corroded connection somewhere that could be addressed to resolve the issue. And they might have some other suggestions as well if it does add up. Good luck with it..

 

[Old Mud]

Thanks again Bill, think ill do just that. There are no corroded connections or shorts anywhere on my boat. Although it looks like a Bum Boat I'm pretty anal about the mechanical condition. I hate surprises

I'm going to copy down all the current needed on a regular biases just to be sure what I can expect.

No expert here but if you are killing your battery, even a deep cycle won't give you long life, longer than a starting battery but not long.
So a larger capacity battery, that will only be drawn down 50% max is what you need. You could also look at the other side of the picture and lighten your load with LED lights, they can be inexpensive now especially if they don't say marine on them.
If your run in is long enough or your alternator large enough or you have a good regulator, or you recharge at a dock, you might eliminate the generator & it's gasoline altogether. Gasoline aboard a diesel vessel can nullify your insurance.

Just as a rough est, standard marine group 24, at 15 amps draw will give you 5 hours use.

Thanks for all the good info. I went with a Exide 27 Dual purpose on that side as per recommendations from "Ed" couldn't go to the bigger batts because of space. That should give me a little more but still not an Ideal situation. We'll see come June 1st.
