Any suggestions for purchasing an on board battery charger to be used on a new Montauk. Interest in something small in size that i could leave in the console and plug in when im not using the boat. Please let me know if anyone has done this .......your experience .......and input.....brand to buy ......and cost.

tabasco with the older O/B and there low charging system there was a need to charge the batt. the newer engions they haveing a larger charging system I don't see the need to charge the batt. (if you use the boat) my two cents

It depends how long the boat sits between uses.
I didn't think chargers were necessary until the
boat sat for five weeks, then wouldn't start at
the ramp. I carry jumper cables so it was no
big deal, but I got a smart trickle charger.
I rewired the cigarette ligher so it was on the
battery side of the Accessory switch (that is,
always hot), put a cigarette lighter plug on
the charger, and just set the charger on the
console (the boat is garaged).

There's basically one maker of smart chargers
that turn up under a bunch of brand names.
They are about an inch thick, black, with
six sides. Be sure to get one with a second
LED that tells you when it's done. West
Marine has them, Sears has them. About $30.

If your boat is stored outside, there are
power plugs you can mount in the side of the
console so you can keep it locked up.

My Corvette, which is driven only a few times
a year, has been on one of these for 10 years
with the same battery.

Do these charges automatically shut off when fully charged?

Tabasco - I wouldn't worry about it. The secret is a good quality, fully charged battery. During our winter when I have the boat under the 'winter' tarp for perhaps 6 months, sometimes I will leave the battery in the boat - and in the spring (around 4/1) the battery is basically still fully charged. As someone mentioned, jumper cables is a good idea - and in my boat you will find a good, heavy duty pair - just cheap insurance. ---- Jerry/Idaho

I put a Dual Pro charger on my Montauk early last year and just used it for the first time this month. I mounted it up high in the console on the fwd side. I have two AGM batteries in the console as well but I found that I actually didn't need an onboard charger as much as I thought I would.

This charger is "smart" and will not overcharge the batteries. Guest is another good brand to consider for a small onboard charger.

I use the same 1 1/2 amp trickle charger that Chuck uses. Got mine at Walmart for $19.

Since I have two batteries in the boat, I put a permanent set of 16 gauge leads into each battery, so I can switch back and forth, terminating with one of those little flat plastic 2 prong connectors (like a trailer connector) under the gunwales. Put same on the charger leads. Then I just plug the charger leads to these battery leads, and plug in the charger. A red light tells you when it's fully charged.

The charger does not have to be mounted onboard, nor does the battery box have to be accessed once the pigtail is installed in the boat. Charger stays in the garage when the boat goes out.

During the winter, when the batteries are out of the boat, I use this charger in the house, about once a month. Highly recommended, best $19 I ever spent.

The smart chargers switch to a real slow
trickle (really doesn't matter which) when
the battery is charged. That's what makes
them smart.

The maker I mentioned is Schmacher (sp?).

Mmmm, I don't find them in the latest West

I have mounted the guest onboard charger
on two diffrent whalers. Both in the console.

I am going to mount one on my Outrage when
I get a chance.I am concerned with wash down pump,baitwell pump,fishbox pumpout,fresh
water pump,macerator pump,lights,radios,and electronics my chances are better if I,m
sure I leave the dock with fully charged

I seen a battery charger at the boat show
charging while fully submerged in water.
Now thats a waterproof battery charger.

I installed a Guest dual bank on-board charger on my boat. Connected the cables to the batteries, plugged in the AC and that's it.

The peace of mind that when I get ready to go fishing, my batteries are fully charged is worth the cost. No hassle, no jumpers, just go....

The batteries are charged the correct way, topped off, no worry about "frying" them. Great investment.

I also installed a GUEST dual-bank on board charger. It connects using the (30 AMP?) shorepower outlet on the console and its been great.

I agree that in the normal course of events you should not need an onboard charger, but if you do decide to get one I would also vote for the Guest chargers, models 2607, 2608, or 2613. Among other things, they are waterproof (or at least so claims Guest). You can see them at
