Battery

[sailnoproblem]

I just finished rebuilding my Atomic 4 on a Tartan 34C (1970) Hull#68. The boat was purchased about a year ago and have been working on it ever since.
Other then a minimal amout of electronics, spreader and running lights. I don't have much of a draw.
Can someone recomend the battery (2) I would need?
Regards

Derpends a lot on how ya gonna use the boat and where it is kept.. If you are planning on day sailing and weekending, a couple of 100+ ampere hour wet cells will be fine. especially if kept on a good charger with a float that turns the charger off when the batts are full.. A couple of these are fine: http://www.walmart.com/ip/EverStart-Maxx-Group-Size-29-Marine-Battery/20531539#Specifications
Made by Johnson Controls and 114 amp hour rating.
If she stays on a mooring, you should have some other charging arrangement, like solar or wind to keep the batts topped off. These are fine for cranking the engine as well as house duty.

Thanks for the info. She'll be kept at a dock which will make it easy to keep the batts charged. I wasn't sure of the amp house, thanks also for that info..
Best regards,

It depends a little on how much room you have available for your batteries. We can assume you're not interested in making any major changes to whatever battery box(es) you have now?

My first choice for a battery would be two 6v golf cart batteries wired in series for 12v. Get 'em at Sam's Club for about 72 bucks each. Don't get gels or AGMs...just regular ol' flooded lead acid batteries. Sam's batteries are Duracells by Eastern Penn and are good quality. Golf cart batteries are of course, deep cycle batteries.

If your needs are as light as you say, you could use the cart batts for both starting and for the "house".

My setup is the 6v cart batteries for starting and house, with a Sam's Club group 24 starting battery (NOT deep cycle) for emergency starting. This battery will only get used if I happen to run the house batteries down to the point where they can't start the engine.

If you're wondering about the golf cart batts, I suggest you do a search on this site and you'll quickly find the reasoning behind them.
