How come the manual for my Honda 15HP O/B clearly states that the alternator is not designed to charge a "deep-cycle" battery? I know what a deep cycle battery is. What's the difference between charging one of those, or another type of battery?
Some outboards have a separate lighting or charging coil alongside the primary ignition coils inside the flywheel ,
To charge a battery you need Dc current , the coil produces Ac ok for lights so you need a Rectifier to change it to Dc if ones not fitted ( most motorcycle ones will fit )
The 2 wires that you may have coming out on your engine will run Nav lights But the faster you go the more electric the engine makes and without some sort of voltage regulater the bulbs will get brighter until they blow or if it's a battery it will over charge .
Old post but someone might need the correct answer.
Your charge controller is not buildt to load a flat battery.
The controller might overheat and burn up if connected to a totally drained battery.
In other words it's intended for like a MC- battery, not a car battery and definitly not a large deep-cycle marine battery that you drain much between charges
Heh, wasn't really expecting you to be waching this still.
Anyway I should perhaps explain it a bit further.
A flat start battery dont draw much current initially when you start to charge it.
A flat deep cycle battery sucks up Amps like mad when you start to charge it.
So actually a car battery might work fine.
If concerned run the motor in 5 minute intervals and let it cool down between.
Or better yet install an Amp-meter and keep the charge below your engines maximum rating. This could probably be done by keepeing the rev's down.
At idle there should probably be no risk of damaging the regulator or coils no matter what battery you use.
Some regulators may not charge at all at idle though.

deep-cycle" battery ( how many amp Hour)
I have used a leisure and car battery over the last 6 years (if I remember correctly about 85amp) Changing after 2 years
I run chart plotter,garmin 550 plus several instrument gauges also have VHF Radio wired in
One battery (prob only room for one)
always take one those car starter kits

Not had any reel problems am I pushing it
like to keep it to one battery
Going to buy new which one

I was thinking some thing like this
What do you think
Suitable for
Caravans, Boats, RV, Leisure use and more.
This is a Heavy Duty Domestic battery and it's purpose is to run applications with it's deep cycling capabilities
Warranty
4 YEARS
Description
This range of Leisure / Marine batteries are of a lead calcium construction which means the plates have been hardened, therefore giving the battery a longer life and better starting capabilities than your conventional leisure batteries. These batteries come with a 4 Year Warranty and are perfect for domestic use.
This battery comes fully charged and ready for use
It is a DEEP CYCLE battery, which means unlike a car battery, they can handle being discharged to a higher capacity and recharged again without affecting the future performance of the battery. Another thing to note about these batteries which is vital is that when charging and discharging they have 250 life cycles.
I'd get a gel cell if possible and you can find one big enough. AGM as an alternative. They don't have unsupported plates or liquid electrolyte that are more shock sensitive and may release gas when charging (though the one you have found looks to be a sealed unit so this may not be a problem)
