Hey everybody. I've got a '91 Hunter 27 sailboat that wasn't used much last summer, not at all this past winter, and only twice this summer. Went down there last week to do some maintenance and the battery switch and meter reads no current at all on one of the two batteries. I guess this means the battery is a gonner.

What could this possibly be besides the battery and how could I check it?

Also, I'd like to have the replacement battery with me the next time I go down, but I have no idea what kind of battery to look for other than a marine battery. I know the size and the dang weight of the ones in the now but other than that I know nothing about them.

What kind / amp / voltage? battery should I look for to replace it?

Thanks

Need more info. You mention you have more then one battery. One is likely a house battery to run your electronics, lights, etc... and the other is likely a starting battery for the motor. All you really need to know is its purpose on the vessel and what group size it is for replacement. Reading that the boat is rarely ever used do you have some kind of charger \ battery tender on board to keep the battery charged? Are the batteries stored in the boat and connected during the winter storage? Age / Cold / and non use and servicing can kill a battery. You can always pull the bad unit and take it to any big name auto parts store and they can load test it for you to see its health but the battery should be in a charged state before the testing. As far as on board testing you can take a multi meter to the terminals and should see between 13.7 and 14.3 volts on a charged unit.
