Question: I have 4 batteries in my boat.  3 in series for the 36V trolling motor and the cranking battery. Can I charge without disconnecting the 36V batteries?
Document: I like that I can charge batteries of different types at one time. This is a very slow charger at 4.4 amps, so if you need a quick charger, look elsewhere. I leave this charger on my boat batteries whenever the boat is parked. I have one glass mat battery (Optima red top) and one deep cycle battery. Overall, this product works really well, especially if you have an over-night period when you can charge batteries.
I love the ability to charge 4 batteries at once, it's not a super fast charger but will do the job on almost any battery voltage and type which is a definite plus.
I put the particular battery charger through its paces and it simply blew me away with its ability to charge 4 large 12v military batteries that completed a 24v 4 bank system that was almost completely dead. I was looking at a $1100 battery replacement cost if this unit didn't preform.
The charger only comes with 2 battery clips and 2 battery eyelet connectors. I was unable to use the eyelet connectors, so I could only charge 2 batteries at the same time. I contacted customer service to see if they would exchange the eyelet connectors for clips, and they responded that they do not make exchanges. They said I needed to purchase 2 clips in order to charge 4 batteries.
Boy am i glad i have this charger keeping my batteries at optimal charge. It will even fix and maintain batteries that are slightly sulphided. These also hardly use any electric at all.It came with 2 clip on ,2 lugged ends(for permanent attachment ,for plug and play )4 - 10 ft extensions.I think i will buy 2 more lugged end attachments .This way all my vehicles will have plug and unplug capabilities.
Wish I had known about these sooner. Once friend or family sees the charger in action, it is put on their wish list. We have this charger installed in our barn attached to three JD tractors and a JD lawn mower. The charger is a battery saver and saves us from having to make trips to the barn and allow running times to charge batteries during the winter. Because of infrequent use, the life of the tractor batteries were short requiring frequent removal and costly replacement and disposal.
This the most awesome charger ever.I have 3 hooked up keeping those batteries at optimal charged state.So when spring comes my mower and motorcycle will fire right up.I hooked them up with the plug in cords .So all i have to do is unplug,start and go.When I'm done just plug back in.I leave them on full time.
Great unit, will buy another one next year. Hooked it up to 4 batteries and took a few days to great them all to full charge, but now they will be good all winter
I mounted this product on the post of a shelf that holds spare batteries. Over time our spares would discharge. Keeping them on a charger was a total mess with wires in a rat's nest. Now we can just walk by and see that the lights are all the way to green. Even new batteries take an initial charge, which is to be expected since there is no telling when they were actually filled with acid. Another incredible use is keeping 12 volt gel cells charged.
The only downside to this model is the limited current capability. If you have a battery that&#8217;s been run completely or almost dead, and you&#8217;re trying to revive it, you&#8217;ll need to hook it up to a traditional high-current fast charger for an hour or so to build a little charge. Then you can put it on the NOCO and leave it for as long as you like.
