I will soon be replacing the two batteries in my Oday 28 and need some advice. My boat is docked in E. Tennessee, stays hooked up to shore power and is equipped with a battery charger to keep them topped off. I was thinking of a couple of deep cycle batteries from Sam's club to keep cost down. We occasionally anchor out but I have installed AA powered LED lights for the interior and a solar powered anchor light. That leaves only 2 interior lights and the cd player to run off the ship batteries. Any thoughts?? As always, I greatly appreciate everyones help. max :confused:

If you have 2 deep cycle batteries you should be more then fine. We anchor out most outtings on our Chrysler C-26 and with our solar panel and never had to charge the batteries off shore power. I believe we use more power then you.

For overnight and weekend stuff... I think the 60 dollar batteries are fine.. I replaced my gel batteries with Costco group 27's, wet cell... I have a smart charger. The are 1/4 the price of new gel or agm units. I got 42 months off the first set (36 mo) .. but when the go.. they go.. Replace them in 2007 so it's time to start checking them a bit more often... but.. the math is right. 7 years for $120 per bank.

For longer range cruising and harder use.. I'd splurge and go with the high end agms.

My 2 cheapie Group 24 wet cell batteries are now coming to the end of their lives -- after almost 8 years in service. I will replace them with the same cheap Group 24s, probably from Sears for about $60 each. But then my batteries have a pretty easy life: just start the Yanmar 2GM20F, run my depth and knotmeter, power the VHF, and GPS. I hardly ever use them for house power, preferring candles, oil lamps, and electrical devices like CD players that have their own batteries. I only connect the batteries up to a shore powered charger a few times a season and then only for an hour at a time. In the interim, I leave a 5-watt solar maintainer panel connected to one or the other battery and alternate it after each sail. This system has worked nicely for me....

I have 2 Group 27 batteries in my Crown 28, and they run the fridge, the stereo, the cabin lights and the anchor light, etc. One thing I've noticed is while sailing, the Garmin 420S takes a LOT of power! But I have an 80W solar panel to keep it topped up.

I'd say a deep cycle Group 27 house battery and a starting/deepcycle battery for starting would be fine. I got a nice 95 A-H battery from Costco which would be great for a house battery. If you have a GOOD smart charger, the battery should last 5 years or more.
