Running the motor
Running the motor should be more than enough only time I give mine a top up is when it has been sitting around for a couple of months

when your engine is running,
when your engine is running, its charging the battery, so technically you are always charging it :-) But yes, better to keep it charged then letting it go flat, that will cause it to die prematurley.
Best bet is to get a decent multi-stage charger to keep the battery in tip top state.

I always top mine up with my ctek. Will increase your battery life! But technically after a good run it should be fully charged.

Best to buy a automatic chargers like a cteck or similar so the battery is always charged.

If you have a cheap single
If you have a cheap single stage charger..... toss it in the bin. As others have said, get a decent Cteck or projecta multi stage charger.
If you spent a long time running on battery and you run back to the ramp is short you may want to top the battery up after the days outing. With a good charger this will do no harm and extend your battery life. Also is you are not using your boat for any extended time it would pay to put on charge for a couple of days every month.
A well charged battery is a happy battery!

I have a Cteck constantly
I have a Cteck constantly connected when engines not running to my batts and im going 3 yrs on the same set of batteries now. Will probably change over one bank in the next 6 months for new one set just to be sure.

If your batteries are
If your batteries are connected in banks change them all at the same time (sounds like thats what you have in mind) otherwise the old battery will run the new one down and it won't last.

you can get a Ctek 5 amp off
you can get a Ctek 5 amp off Ebay for $80 from Autoelecau
One point though-if you guys ALWAYS leave your batteries on trickle charge when not in use-how will you know that it will no longer hold a charge except when you stop at sea for a few hours and it lets you down?

Thats easy, when i jump in
Thats easy, when i jump in the boat a week later and see i forgot to unplug the engel and i can still start the motor i know its all good haha
But yeh that is a very good point. I dont leave mine on trickle i just top it up after a run when im not going to use it for a while. Especially if say i am chasing pinkies with a 5 minute run back to the ramp, with the lights, radios, fridge, live bait tank and stereo on !!

i'm with Rob on this one, you
i'm with Rob on this one, you don't trickle charge your car now do you. Just make it habit to change your battery/ies every 2 years and have a charger on hand in case it hasn't been used for a couple of months

only difference is that the
only difference is that the car gets run on a regular basis (and get the top up charge everyday or so) where as some boats can be months between outings. Proper marine batteries are a must (don't just chuck a car battery in the boat) they are built differently - car battery is mainly built to supply cranking amps whereas proper marine battery will give cranking amps to start the motor and will be able to run electrics, lights etc with the motor off (not being charged) Marine batteries will handle being run down to around 50% flat without it stuufing the battery as long as its charged back up soon after. Discharge an auto battery more than 20% and beyond that its going to suffer and have a short life.

Bottom line Poser, for my
Bottom line Poser, for my money-give it a charge when you get home if you haven't run it much in the water.
Leave it for a month and try starting it. If it struggles you have a problem, whether parasitic drain or a battery failing.
Depending on the type it should only lose a few % tops in that period.

For the record rob I'm with
For the record rob I'm with you, I don't leave may batt on charge at all. After pushing the boat in the shed I'll chuck the charger (old type) on for an hour or so until I see the amps drop and then I know its pretty charged. Often gets left for long periods and I don't have any problem. As you say in April pulled it out of the shed and went to raise the motor - would hardly raise it so got a new batt. (that battery was 4 years old so seem to get plenty of life out of them without having trickle feed).. I only have one batt but carry a jumper pack just in case - ahven't had to use it yet..

batteries
can anybody honestly tell me the differences between an auto and a marine battery i dont think theres much diffference? was always asked what sticker we wanted to put on the battery thats all ;)
poser there is nothing wrong with charging a battery fairly often during its life just do not let it boil while doing so, buy a multimeter and just keep it above 13.8v and you will never have any dramas

There is a massive difference. Theres a heap of threads on this already. Thicker plates, more like a dual purpose battery.Can be discharged more. A automotive battery will not last

i know i will get shouted down but
back in the day up north we used lead acid battery's to power the coms systems that were charged constantly by a battery charger (because there weren't any decent dc power supply's in those days) the problem was we were regularly changing the battery's out , the reason ? because lead acid battery's like to be charged and discharged so if they are constantly charged and not discharged they have a shorter life span , when I moved over to the marine dept at rio one of my jobs was to maintain the nav aids which were power by a lead acid battery which were charged from a solar panel but there was no regulation of the charge from the solar panel ( even though the supplier said they were self regulating) we ended up fitting regulators and quadrupled the battery life on the nav aid battery's , in the end we went for gel filed oddesy batteries which in my opinion are fantastic battery's they will even work up side down and hold there charge for months and have a ccr capacity of batteries twice there size but that's just my opinion, the worst thing you can ever do to a lead acid battery is sit it on a cold concrete floor for some reason it just kills them

There is so much info on the net about this subject, if you are really wanting to know, just Google it and read. Batteries and charging have progressed in design and method so much as compared with 10 years ago. Like I said the info is there, big articles, drawings and pictures explaining it all.

charging batteries
Go to your local camping shop and get 2 small solar pannels connect 1 to each battery there about $20 each thay keep the acid turning over which stops the plates from breaking down and keeps the batteries charged.My boat sits outside so i leave the panels on the dash. Batteries are 5years old now still like new

There are a lot of myths that are spread about battery charging and storage. Some have an element of truth though that element may be based on battery construction of the early part of last century.

Especially the storage and charging section
Keep your connections tight and maintain your battery with a good quality regulated charger.
