Battery - Maxum Boat Owners Club

Just bought a new 1800MX as a first time boater and the battery is completley dead after a few weeks without using it. This with the main breaker disconnected. My dealer indicates it is the alarm draining the battery within a short while and wants to install a permanent battery charger, which does not feel right. Has anybody experiience / knowledge if the suggested solution is correct or is it just an easy way out overcoming the problem but not really fixing it
Thanks very much for any feedback,

well first off..welcome to the zoo....secondly..I don't know what all eqpt you have on your boat....something may need to keep pwr going to it to maintain memory or maybe a bilge pump goes off from time to time...I just can't answer it..however...if a small charge is rqd..then a batt. charger will keep them topped off....so..yeah..that could be a permenant solution....

Thanks for the response, the boat is on a trailer and the main braker is dsconnected, according to the dealer only the alarm system can use some power. The rest is disconnected all the time via the main breaker.
So, no additional equipment which can drain the battery. Hope this helps to guide me a bit more,

swede....then yeah..in a couple of weeks...the batts would be drained....personally ..I'd have it on a trickle charger if it's stored at home all the time...you can leave it in the cockpit and take it out when you go out..the engine will keep the batt's charged while underway...the other thing is I'd have 2 batt's on it if you only have one....2 is always better than one......

On the topic of charging, is it ok to leave the battery charger on my 2001 2500scr on all the time while on shore power?

would recomend you check your fluid levels regularly if you leave on permanent charge dont want to cook the batteries as i found out to my cost.

What sort of alarm do you have on there? Assuming you only have the one battery on board it would have to be a pretty large battery in order to start the engine and thus probably shouldnt be completely drained in only a few weeks. I would check the fluid levels in your battery, or put a multimeter across it to make sure it's holding it's charge (could just be a poorly battery, it happens) but also check the connections on your alarm for anything that may be draining the battery i.e. bridged earth connections, 'fuzzy'/corroded connectors or anything else that would drive the current up and thus discharge the battery quicker. By all means stick a battery charger on there too but it also might be a wise idea to check the above mentioned points aswell.

Only just realised how old this post is, should probably read the info more before I go ahead and chime in with my 2p worth. :-)
