Look at your local Sam's Club. Group 27's are ~ 50.00 here. 24s should be a bit cheaper.

Yep, Sam's Club or Wal-Mart. Remember to take your old ones to trade in.

Alan... I just replaced my "house" batteries with 2- 6 volt deep cycle golf cart batteries (wired in series). I understand alot of cruisers do this. I'm using a small 12 volt for engine start mounted back in the port lazarette.

Thanks for your replies, I am going to compare warranty and cycles etc. Auto zone has a deep cycle battery for 49.88 but it only has a 30 day replacement warranty and24 month pro rated after that. I am going to check at Sams/Walmart if those are good quality batteries Thanks again. I will let you know what I find out.

are we talking about Wal-Mart's deep cycle trolling batteries?
I have two of these one 105 AH and another 115 AH they work great.
I know that automotive batteries usually are no good in a long discharge mode on a sailboat, since auto batteries are designed for quick bursts needed for starting a motor.

just wondered, though we have discussed many things here I don't remember any threads on juice boxes. (not the ones in your kids lunch box)

I picked up a couple marine deep cycle batteries at Costco a year ago and they're holding up just fine. I think I paid around $27 a piece for them.

For my house bank, I use a pair of the same Sam's/Wal-Mart 105 AH group-27 flooded cell trolling motor or maybe dual purpose (crank/deep cycle) batteries I think John V. is talking about. For my cranking battery, I have a flooded cell dual purpose group-24.

And yes, deep cycling an automotive battery will shorten its life drastically!

Andy, the two 6-volt deep cycle golf cart battery house bank is a good idea too. Do you know what size their case is? Do the fit in a group-24 or group-27 box? Or are they taller?

Here is a link to specs on the Trojan t105 6v deep cycle. This battery was one of the highest rated batteries by Practical Sailor a couple of years ago. That was in terms of cost per amp hr capacity.

I'm admitting my ignorance about batteries here, but for starting my 10hp diesel inboard, do I want to use a deep cycle marine battery? What type is recommended for the second which can be switched to for extended use of stereo, lights, tillerpilot, etc?

Deep cycle and starting batteries are vastly different.

Here's a link to a good reference: http://www.uuhome.de/william.darden/carfaq.htm

Also West Marine Advisors: http://www.westmarine.com/webapp/wcs/stores/servlet/WestAdvisorListView?storeId=10001&langId=-1&catalogId=10001

Any Google search on batteries will give you more than you'd ever want to learn. The Trojan site is also very good.

Happy reading,

Stu

Well, I have taken your advice and gone to Wal-mart and looked at the group 24 deep cycle batteries for $59.86 Each, I also checked consumer reports for car batteries and they talked good about diehard @ Sears $66.00 + each. The Walmart batteries have a little more reserve capacity and more CCA -not that I need them- than the diehard. Warranty for the diehard is prorated 6 months longer. I like the deep cycle batteries and like Leon said you dont want to deep cycle it dead too often otherwise it wont come back. I would designate one battery for house and one for starting my 9.9 hp outboard. It looks like now that walmart is going to get my money AND OLD Batteries. Sorry there is NO Costco around here. I will keep you informed Alan '87 Catalina 25 TR/SK #5612 "Leprechaun"

I am using absorbed glass mat batteries, one group 27, and one group 24. They were very expensive. I bought them so as not to get hydrogen, or chlorine outgassing, plus they work underwater. I'm not really impressed with them. I'm using a statpower charger for 110 charging, and a charge controller for my solar, and nothing on the Honda alternator. They just don't seem to hold onto many amps, and I even replaced a lot of my lights with LED's.
When I need replacements I'm going back to the lead acid batteries.

Alan,

Andy is right on about using a small 12 volt battery in the port locker for outboard engine starting. I picked up a lawn tractor battery at Fleet Farm for a little under $12 and it works great. No messing with wiring and switches, just run the wires from the outboard to the locker. Keep it simple.

For outboard eqipped boats I would recommend using two identical deep discharge batteries for flexibility, but for your diesel which draws much more current on starting, you'd be better off with a designated starting battery and a deep discharge battery for house use.

Mark, I think thats the way to go, I will take one battery and desinate it as a starting battery-I have a battery switch-than use the other as a house battery. I looked at AGM batteries and I cant justify the cost difference in my mind. I spoke with my outboard motor repair guys and they advise that the motor has a charger on it and will recharge the battery -starting- in about 20 minutes of use,not that it will happen but it is intersting to note. Thanks for all your Input.

My Sam's Club Stowaway 105Ah 180 minute reserve capacity group 27 battery was manufactured by Exide.
