About those batteries?
The old boat had a couple of 4D's at 220 Amp each. The new boat is
currently using fairly standard 12 volt RV size batteries at 110 ratings each. I'm thinking of going to the 6 volt variety as I have to go back up to or near 400 Amp hours of storage. Which size, which voltage, and why? If six volt are the fairly inexpensive one's from Costco (golf cart batteries)useful or should I just spend the money at West Marine? Tanks Michael |

Trojan battery has the following deep cycle batteries suitable for house
batteries The J250G (220 Ahr @ 20 hr rate) $100.95 ea. plus any taxes The J305G (285 Ahr @ 20 hr rate) $130.95 ea. plus any taxes The J305HC (335 Ahr @ 20 hr rate) $169.95 ea. plus any taxes http://www.trojanbattery.com/productspecsguide.pdf The West Marine 6V battery is a Trojan T-105 (225 Ahr @ 20 hr rate). Catalog price is 109.99 plus tax. West Marine catalog conservatively rates battery @ 215 Ahrs Kelton s/v Isle Escape Schoonertrash wrote: The old boat had a couple of 4D's at 220 Amp each.

I bought 6 new real Trojan 6 V T-105's a year ago for $65 ea from a
Trojan dealer. They replaced 2 8D's in exactly the same footprint. they're a bit higher but same footpring and got 50% more AH than the 2 8D's - better yet I can lift them without a problem. They have threaded stud terminals which I like a lot better than the clamp terminals. Stay away from West Marine and get the real Trojans from a good dealer, not Costco, Sams etc. Real Trojans are date stamped on the battery terminals with a 2 character date code month letter, year number so you can see you're getting fresh batteries. One other point - I really like the T-105 caps - much better than any other I've used.

Hello:
I just replaced my 400 ah house bank. DO NOT go to West Marine. Look first to stores that supply other items to a specific "industry" or field. For example, In the NW there is a chain farm/ranch supply store namend D&B Supply. They sell 6v Trojan T-105 (225 Ahr @ 20 hr rate)for $59.00 each I guess they figure the poor ranchers can't afford to shop at West Marine. I also get antibotics by the pint for about $14.00 and the feed store. If you don't mind giving your pet a shot you can save $100s on vet bills. Same idea. Do not get stuck with the idea that something for a boat must be "marine." Chris Freya 39 "Schoonertrash" wrote in message ... The old boat had a couple of 4D's at 220 Amp each.

Those cheap golf cart batteries are a great buy. They work fine.....
Of course, I'm not a MARINE dealer....(c; Everybody knows you need $469 GSM "boat" batteries in red, orange or yellow cases. Black clashes with the white fiberglass...... We installed two banks of 350AH golf cart batteries on Lionheart. They are twice as high as the bargains at Costco (hardly a wholesale anything outlet like Sam's). We needed 700AH to run the hydraulic B&G autopilot pump on Network Pilot.....They work great and have the same footprint as the shorter ones.

I orig. had the 2 8d's in parallel as one bank and another starting
battery - so the 6 x 6v were wired in series parallel as one bank. On Sat, 01 Nov 2003 21:34:34 GMT, "Fred Miller" wrote: Olly wrote in message ...

Here's the reference you want in the Pacific NW. 6-volt batteries which you
mount in series - two for 12V with great amp-hours. Use two banks with a switch. For us, it replaces a generator at a quiet anchorage using an inverter. Once we get underway we recharge with a cruise generator. And I use a CPAP machine all night. Plenty of power. And all the guys at this place have been to the Trojan factory to learn batteries from the box up. Schoonertrash wrote: The old boat had a couple of 4D's at 220 Amp each.

I'm not saying *don't* spend the money at West Marine, although I personally would not. At WM you do get a better guarantee than you're likely to get at any local battery discounter. But before you go seriously shopping for new batteries, check into more info. Here are some links i found helpful when pondering the same question earlier this year http://bart.ccis.com/home/mnemeth/12volt/12volt.htm http://www.marine-electronics.net/te..._faq/b_faq.htm And in the end, since we already had the wiring & the cases for two Grp 31 batteries, I bought two Excide Grp 31 dual purpose (700 CCA and 115 AH each) at Agri-Supply http://www.agri-supply.com/ They have a big outlet which is not too far off our track from home down to the boat. Unfortunately, the particular batteries I bought were at the end of their shelf life and have not proved very satisfactory. Furthermore, they are at or below the minimum bank we need for life a-cruising with our electrically profligate lifestyle. My plan is to get two new Grp 31s for starting and short term house loads, supplemented with a big bank of 6V golf cart type batteries when I can get around to building in a case for them. Another issue we pondered... the battery charger is a KEY part of the system. You need to match your amp hours to your charging capacity. Another key point is that a modern hi-tech 3 stage "smart" charger will be a zillion percent more effective, and will dramatically increase the life of whatever batteries you choose, than anything cheaper or older. We replaced a quite impressive looking ferrous core charger than had been boiling away batteries at the rate of one per year for the former owners. Plus it did not have an equalizing function.
