I will be changing the positive load cable to the opposite end of the bank that the neg is connected to.
That's what i said back in #52.

...and many of us had 2-3 12V 8D battery boxes on our boats. The footprint of 3 GCs matches that of a single 8D. Addi 6 GCs in place of 2 8Ds and you have a 50% increase in AH capacity at little if any cost increase.

fryedaze, will you post a photo of the correct way when you get it done? This has been very helpful to me as I am about to do the same thing in our boat.

Thanks Dave. Now it makes sense with what you said and the photo.

I have had very good luck with trojan T125 batteries. I chose them over the T105 and cost is minimal more. I have six of them as house batteries. My problem is charging them on anchor. I only have a 40 Amp charger.

I just swapped out four T105s for 8 Crown CR235. The new bank is 940 amp-hrs and I have the same issue with charging at anchor. My charger is also 40 amps. The 80 and 100 amp chrgers are pretty pricey.

I just took a chance this weekend on some 6 volt golf carts for my house bank. I bought them at advance auto parts. They had been on the shelf for 11 months. They dropped the price to $50.00 each .I think retail price was around $ 115.00 .I guess time will tell . I only needed 4 they had 6.They would only give me 90 day warranty.

You can't go wrong with that deal. You probably know, charge them well before using them. I don't think you'll have a problem with them as long as the acid is above the plates.

Here is specs on them. I also heard Crown is better now. I'll look at them before I buy. My real problem is a large charger and it looks like the combo inverter/chargers is the best value.

Notice that "East Penn" (EP) battery manufacturer is listed six times. As I understand it, via our local Batteries Plus (BP) franchise owner... EP manufactures the majority of starter and deep cell batteries for BP Company (currently 570 outlets). When I heard this about BP marine batteries (some years ago), via research on the net I read that EP was about the largest, oldest, and most trusted battery manufacturer in the U.S. XTREME is the moniker/brand-name that BP places on their wet cell (deep cycle and starter) marine batteries... the type I use!

Any hooooo... Since BP opened in our area I and my extended family have been purchasing all our battery needs there. Battery power and use-longevity (of all type batteries) have for years now provided us remarkably positive results. BP battery costs are about the lowest on the market. Consistent first name personal service we get at BP is another factor we greatly appreciate.

Interesting post, John & Art....

When I was installing my SOC monitor, I tried to get the Peukert Exponent from Power Stride. They referred me to East Penn as that is where they get their 8D AGMs from. I'd never heard of East Penn until now. Apparently they "private label" all their batteries as I've never seen or heard of an East Penn line.

I purchased my AGM 4D batteries from a marina that bought them from Batteries Plus, and they are manufactured by East Penn as well. BP's price to the marina was very reasonable and I benefitted from that.

Last I heard...West marine brand was East Penn also...they did extensive testing and agreed for the buck they were worth putting their name on.

It looks like I am going with the Platinum Die Hard. Certainly not the cheapest at about $240 per but not the most expensive either. And Built by Odyssey which is one of the best batteries out there. They have received rave reviews across cyberspace and a 3 year full replacement warranty. A big factor in this decision is being able to drive 5 miles down the street for face to face warranty service should any issues rear their ugly heads.

I called Batteries Plus in my area and their Group 31 marine AGM was $360!!!....manufactured by X2...allegedly a spin off of Odyssey according to the guy on the phone.

>My real problem is a large charger and it looks like the combo inverter/chargers is the best value.<

The new ones are very smart and the units that pass thru an adjustable amount of amps , then add to the line power automatically are probably the best to live with.

These can boost a small noisemaker that is properly working very hard to start an additional Air Cond , or give a good lifestyle on a cruddy power hose.

When the smart inverter dies , you loose the batt charger too.

Not for the cruising belt and suspenders folks .

Baker, if you can find a local marine supplier who does business with BP, you might try pricing through them. I got mine from a local marina for 1/3 less than West Marine wanted for the same East Penn battery. I believe they added 10% to wholesale to handle the transaction. It is worth asking.

I have nothing for or against either company - just relating my experience.

I get East Penn Deka batteries from a local NON-marine battery supplier, out in the industrial park area. Quite a bit less expensive than West Marine - most recently $197 for g31 Deka AGM's.
