looking for a batterie for my dinghie to power nav lights, sonar/gps, radio & bilge just wondering a few things.

go the biggest you can fit
go the biggest you can fit in .. 660cca or better is always nice .. usually they are better down the back opposite the fuel tank in a tinnie .. there are brackets avaliable for them or the black battery covers . no need to be marine grade ... im running 2 ac delco's atm. just as long as they have platelok tech they are fine

Actually they are supposed
Actually they are supposed to be marine batteries fitted to boats. They are specially made to suit the pounding that boats give them. Otherwise the plates "can" come loose and do damage.

you dont need a big batt
i use a 20 amp hour batt (out of my kids quad bike)in my tinny for electric fuel pump bilge and sounder and have never runn it flat and if you keep it near the back of the tinny the pounding dosnt affect it . i have used n70 in the past but they are to heavy and leave big dents in the bottom off the boat

Hi. I have two Supercharge
Hi.
I have two Supercharge 85a in Stacer. 90 Opti.
One for starter only. T'other for electronics.
Couple them both when using bilge pump.
On 3.75 Tinnie. 15hp Yammie.
I have a 25a Gel battery. Little square one.
Fits nicely into a small drink Esky.
with some Styrene sheet packing.
It runs everything in boat for several days.Sounder
GPS. Radio. Lights. Not a problem.
Have bucket for bailing. Better than any pump.
Can't leak, Can use on it's side or even Upside down.
Dead safe.
This one near 4 yrs now. Still going strong.
Just take one from other boat when taking electric motor along.

i have 2 power crank deep
i have 2 power crank deep cycle marine batts cost $190 each
whatever you get just make sure its a deep cylce
because once you let it go flat you can charge it
on a conventionl type batt every time you let it go flat the chances of recharge dissapear
im not sure why but mabe kempy the auto spark can shed some light on this?
getting the bottom line final answer from a bunch of blokes that use false names and put smiley faces at the end of paragraphs is not the best place in the world to get the information you seek.

a deep cycle battery would
a deep cycle battery would be better the only problem is the are much heavier, half the warranty and cost much more then a standard one. the question really is why are you running it dead flat and they do recharge but it doesnt do them much good but if they are run flat they should be recharged as soon as

battery
I used a small dry cell battery in the hornet for the same functions,i had it permanantly connected to a small solar charger and it was fine,
i assume you dont have a charging circuit on the outboard
