Another battery question

The lid section is built that way to hold the double post batteries, such as Trojans. The side tabs should hold your battery just fine, and there should be plenty of pressure on them. We think we understand, though if your in question an image would help.

the space issues as you move the top of the battery tray to make one side or the other or one end or the other hold on top of the battery. Note that no where does it leave any meat on the battery when one side or end touches the others dont or barely do….hope the pics help… Thanks

set the top at varying heights from side to side and it looks like it will secure against the top on one side and the shelf at about 1 inch down on the other. Interestingly the new battery tray I am installing for my 4th battery is larger then the single tray that came on the boat. The good thing is I can fit the Trojans into those slots now I just need to find another Trojan (Should have kept the one I replaced last year or I can go to a bit smaller AGM for that fourth slot. I need to secure my oil tank down next. Surprising that the oil tank mounts to a thin piece of fiberglass over the center well. Seems strong enough I need to drill and secure it with some through bolts and nuts and finish my battery installations and I will be good to go again. Man is it tight in there with 4 batteries and an oil tank.

Batteries are like tires. You can mix match them, but they do better as matching sets. One brand battery may have a diffeent charge characteristic than the next brand. Different specs on how they are built. From spacing of cells, to composit of metals, to the volume differences in fluids all contribute to the different charging characteristics.

thanks guys, you are probably right BCB i had just under 12 volts on the bad battery then after i added water, not even 1 volt and the small charger i have just kicks on and off. but its just a 6 amp trickle charger, and i bet that my on-board charger (pro mariner) just blew a fuse.

I had several issues with my onboard 3 bank charger (came with the boat) it never fully charged the batteries. I used a different portable battery charger from B-pro with similiar results. I ordered from amazon a Schumacher 10-amp speed charge digital charger for $50 it took almost a day to charge all 3 of my batteries. It actually desulfated all 3 batteries. I bought another Schumacher speed charge (15-amp) and took the heavy piece of cra_ charger out of my boat. The batteries are now over 5 years old (group size 27 continentals) and are still going strong, fished big bass last October for 8 hours and they were still at 70%. I would try the 10 amp for $47.56 on amazon and see if it helps you.Last edited by sabreski on January 21st, 2013, 2:08 am, edited 1 time in total.

If you think the problem might be related to the stereo install. Find a buddy who has an AMP clamp multimeter. Charge the battery, after full charge. Let the boat sit an hour or so, clamp the meter around red wire and then black wire off this battery with none of the graphs on. Write down the AMP draw reading, which should be nothing. Start turning on one piece of equipment at a time and see if there is a significant increase. Then take the boat out, and do as you said about idling out and trimming down to see if the draw gets real big. if it all looks like a decent draw, then the battery cant handle it. I will be in Helena this weekend, let me know if I need to bring my meter.
